Heat Transfer Boxes & Systems: A Breeze with the AC Tech MCH Series

/1 Comment/in /by

Epsilon Industries is a supplier of integrated air and fluid side-heat transfer systems including factory built penthouses with mechanical/electrical systems; complete heat transfer packages and refrigeration systems. “One reason for the success of the ‘packaged’ mechanical systems concept,” says Epsilon Sales & Marketing VP, Brad Hughes, “is customers realize they can decrease the total cost and meet their deadlines by utilizing our specialized, highly trained technical staff.” To regulate pumps, chillers and air handlers, Epsilon uses MCH Series drives from Lenze – AC Tech.

What led Hughes to choose the MCH Series? “Our choice of variable frequency drives is a good example of how closely we look at anything that can be done better.” As he explains, “These Lenze – AC Tech drives offer a couple of advantages that make a lot of sense to us, one is the automatic transfer to bypass; the others are the disconnect option, and the on-site warranty.” The automatic-transfer-to-bypass option allows the motor to transfer from drive operation, and continue across the line in bypass mode.

Say there’s an external condition that creates a problem with variable frequency drive operation; like transient voltage harmonics from the utility causing the drive to trip off on a fault. The MCH drive can be configured to attempt several restarts, but if the condition will not clear, the automatic-transfer to-bypass function will transfer from drive operation to line power, without any human intervention. If the drive did not have this capability, an experienced, trained operator would have to be on hand to ascertain there was a problem, and then he would have to manually put the drive into bypass mode.

“Utilizing the MCH drive is a way for us to make sure we maintain uninterrupted service, no ifs or buts,” summarizes Hughes. Once again, dependability under demanding circumstances and assuring their customers that the systems are going to offer top performance is a crucial aspect of Epsilon’s market success. Epsilon has found a niche and is taking full advantage of it. Hughes counts on Lenze – AC Tech relating “Demystifying drives is the first step towards making them an integral part of our clients’ design. When we don’t need an expert to understand them, we can really count on them, and move on.”

MCH Series Benefits:

• Automatic Transfer to Bypass Option

• Automatic Disconnect Option

• Keypad Select for HOA (Hands Off/Auto)

• PID Setpoint Control

• Variable Torque Drive

• NEMA 12 Enclosure Available

• RS-485 MODBUS Communication

• Proven Performance & Reliability

Permanent Magnet Servo Motors

Permanent Magnet Servo Motors

/in , /by

Permanent magnet servo motors are also known as brushless servo motors and/or PM (permanent magnet) servo motors. Permanent magnet servo motors are used when an industrial application requires high performance and precise speed regulation. Permanent magnet servo motors are manufactured with a designated controller known as a servo drive or servo driver. Permanent magnet servo motors use position feedback to precisely regulate motor control by being paired with an encoder. Encoders measure a brushless servo motor’s output shaft position which is compared to the command position. When the servo motor output shaft doesn’t match the demand signal, an error signal is sent to the servo motor controller; the controller adjusts accordingly and sends a signal back to the servo motor until the demand position is met. PM servo controllers (servo drive, driver, etc.) are never included in the base price of the servo motor. Servo motor systems can be expensive but the cost is justified with optimal manufacturing processes via precise speed regulation.

Servo motors output more torque than brushed direct current motors. Brushless servo motors aren’t as loud during operation than brushed direct current servo motors. The lifespan of brushless servo motors exceeds than that of a brushed direct current motor because there aren’t brushes or a commutator to maintain. The idea behind brushless servo motors was to be able to integrate control function of the servo motor with industrial electronic components and personal computers; and to precisely position machines in manufacturing processes. Some manufacturers use brushless servo motors in explosive and dirty environments because brushless servo motors are entirely closed and sealed to prevent dust or sparks to reach the servo motor parts.

Permanent Magnet Servo Motor Design Process

Permanent Magnet Servo MotorsThis process comprises three main steps: Electromagnetic, structural and thermal designs. Electromagnetic design starts with magnetic circuit modeling and parameter optimization with a given set of design specifications. A series of optimizations such as pole number, loading, current density, dimensional limits etc. have to be performed to find the optimum parameters of the motor before proceeding further. When a design is obtained that meets the technical spec, a quick motor simulation and the influence of parameter variation must be carried out using simulation software such as SPEED (PC-BDC Manual, 2002). A detailed electromagnetic finite element analysis (FEA) either in 2D or 3D is the next step to verify that the design meets the specified torque-speed characteristics and performance. After an electromagnetic design is finalized, structural and thermal analyses (MotorCAD Manual 2004) have to be completed. Structural analysis is not a necessity for design on low speed permanent magnet servo motors. If  motor does not meet the structural or thermal tests, then the electromagnetic design study should be repeated for a better design.

Permanent magnet servo motors are widely used in many industrial applications for their small size, higher efficiency, noise-free operation, high speed range and better control. This makes quality of their torque an important issue in wide range of applications including servo applications. For example, permanent magnet servo motors used in defense applications, robotics, servo systems, electric vehicles all require smooth torque operation. One of the most important issues in PM servo motors is the pulsating torque component which is inherent in motor design. If a quality work is not completed during the design stage, this component can lead to mechanical vibrations, acoustic noise, shorter life and drive system problems. In addition, if precautions are not taken, it can lead to serious control issues especially at low speeds. Minimization of the pulsating torque components is of great importance in the design of permanent magnet servo motors. In general, calculation of torque quality is a demanding task since the torque quality calculation does not only consider the torque density of the motor but also consider the pulsating torque component. Therefore, a mathematical approach about torque quality should include harmonic analysis of electric drive system rather than a simple sizing of the motor.

ABB Energy Management Systems

/in , /by

Today industry and commerce are facing an energy challenge. Pressures to reduce energy consumption, lower carbon dioxide emissions and provide secure power supplies are coming from governments, consumers, legislators and shareholders alike. All of these pressures are against a background of ever-rising energy prices and the dramatic effects climate change is having on the environment. As a result, industry and their consumers are demanding ever more energy-efficient products.

The world’s demand for energy is rising steadily. Under current policies, energy demand is set to rise 47 percent between 2008 and 2035, according to the International Energy Agency (IEA), reflecting global economic growth and rising living standards. Electricity demand is expected to grow almost twice as fast, with most of the increase occurring in emerging markets. Helping industries and utilities improve energy efficiency Industry consumes about 42 percent of all electricity generated, according to the IEA. The most energy-intensive industries are cement, chemical, iron and steel.

The energy saving potential in industries and utilities is enormous just in electric motor-driven applications alone: hundreds of millions of electric motors driving machines, compressors, fans, pumps or conveyors in virtually every sector account for about 70 percent of all the electricity that industry uses. More than 90 percent of industrial motors either cannot adjust their power consumption or use very crude methods to do so. Many of these electric motors always run at full speed, regardless of the actual output needed. In many applications, energy use can be cut to one- eighth just by reducing the motor speed by half.

ABB Energy Management Systems Solutions

The most immediate, cost-effective and practical way to address the energy challenge is to grasp the opportunities for energy reduction that come from using energy more efficiently with available and proven technology. ABB energy management systems include variable frequency drives, motors and other technologies to help lower energy use, either by reducing power consumption and losses, improving productivity or through better management of equipment.

With ABB energy management systems there is great potential to save energy and costs in industry. Nearly 70 percent of all electrical energy consumed by industry is used by the millions of electrical motors installed worldwide. Every year, several more million motors are added. These motors are the workhorses of industry, driving machines, compressors, fans, pumps and conveyors in virtually all industrial sectors. Not only are pumps and fans numerous, they also have the greatest energy saving potential. Therefore, targeting pump and fan applications is a great way to begin with ABB energy management systems.

ABB supplies virtually every industry with a broad range of electric motors and variable frequency drives to reduce energy consumption, increase productivity and safeguard quality. Among the industries served are cement, minerals, metals, oil and gas, chemicals, pharmaceuticals, pulp and paper, water, and marine.

During the 40 years since the first variable frequency drives appeared, ABB has delivered millions of units across the globe to every type of application in all industries. During this time, vast experience has been gained of how industry can save energy in the most effective ways. The installed base of ABB drives saved 310 million megawatt-hours (MWh) in 2011, equivalent to the yearly consumption of about 75 million EU households. In terms of CO2 reduction, these savings equate to 260 million tons, more than the yearly emissions of over 65 million cars.

ABB energy management systems use variable frequency drives to reduce the output of an application, such as a pump or a fan, by controlling the speed of the motor, ensuring it runs no faster than it needs. Many motors are oversized to cope with a maximum demand that rarely or never occurs. The drive brings the motor speed down to match the actual demand needed by the application. This often cuts energy consumption by 50 percent and in extreme cases by as much as 90 percent.

When other control methods are used, such as dampers, vanes or valves, the motor runs at full speed and the flow of the output is mechanically restricted. For instance, the flow through a pipeline may be reduced by a valve. This is wasteful, because the motor keeps running at its nominal speed regardless of the demand. The pump delivers maximum output and the excess is reduced at the valve, where the surplus energy is wasted through friction. The relationship between a pump or fan’s speed and its energy need is known as the cube law, because the demand for power increases with the cube of the speed. This means that a small increase in speed requires a lot more power, but also that a modest speed reduction can give significant energy savings. A pump or a fan running at half speed consumes only one-eighth of the power compared to one running at full speed.

In addition to the energy savings, the variable frequency drive delivers accurate control and less mechanical wear, reducing maintenance and extending the life expectancy of the system. ABB energy management systems products range from 0.18 kW to 72 MW, is the widest available from any manufacturer, offering drives for every need. Many of ABB’s drives have built-in energy calculators to monitor energy consumption and savings in kilowatt hours, local currencies and carbon dioxide reductions. The drive’s built-in energy calculators show actual results that can be used as a basis for future energy saving projects.

Variable Frequency Drive Repair

/in , /by

Variable frequency drive repair is an asset to industrial manufacturing because drive replacement is expensive and prolonged lead times for OEM drive repair is a common problem.

Technology has evolved variable frequency drive manufacturers to consistently release new and better drive products for industrial manufacturing. This constant new technology puts the drive manufacturer at an advantage, and the variable frequency drive user at the mercy of purchasing new equipment in place of obsolete and discontinued drive products. Variable frequency drive repair service centers are the backbone of minimizing downtime while maximizing productivity for manufacturers.

Variable frequency drive repair service centers are often the quickest and least expensive means of getting a manufacturer back into production due to variable frequency drive failure. Since minimal downtime is critical for manufacturers, variable frequency drive repair centers offer expedited variable frequency drive repair solutions. Drive repair service centers can often repair failed equipment and get the repaired drive equipment installed and back into production in less time than the drive manufacturer will offer a replacement or repair quote.

Manufacturers should keep spare variable frequency drives for production lines that must continuously operate to meet customer demands. When crucial equipment fails, manufacturers emphasize the importance of installing spare equipment to get production back up; which is then followed by promptly sending out the failed drive for repair. This process will ensure that whenever a piece of equipment fails during production, there is always a rebuilt spare piece of equipment that can be quickly installed to replace failed equipment, to meet production demands.

The objective of Precision Electric variable frequency drive repair is to provide manufacturing facilities with prompt repair services so that manufacturers can meet their customer’s demands. Precision Electric variable frequency drive repair consists of removing all variable frequency drive parts, cleaning parts and all other components, replacement of damaged components, final testing of all electrical components, assembly, final test of drive with electric motor, and safely package and ship drive back to the customer. All variable frequency drive repair work is performed in house by Precision Electric and comes with a 12 month in service warranty.

The ABB ACS550 Series drive finds it’s place as a mid-level applications drive. Typically it is used for open loop applications rather than closed loop. There is an optional encoder card though for users who find themselves in need of a closed loop setup of their motor and drive.

As with the majority of variable frequency drives out there, such as the SMVector, the ACS550 also comes with three operating modes. These operating modes include standard V / Hz control, variable torque control and open loop vector control.  An integrated line filter (or EMC filter) comes standard on any model in an R2 frame or smaller. All boards are coated for harsh environments and each ACS550 includes a swinging choke for superior harmonic reduction.

If you find yourself wanting to know more information on the ACS550 drive simply swing by any ACS550 product page to learn more, you can also grab the manuals while you’re there to get an idea of how to setup your drive. One of the unique features of all ABB drives is the macro system for setting up applications, such as pumps or fans. Each drive comes with preset macros that make the configuration and startup the drive simple.

One confusing aspect of ABB drives is that they tend to come in two separate ratings. There is a “standard rating” and a “heavy duty rating” – heavy duty ratings are typically reserved for applications that are variable torque and may endure extreme loads for up to 10 minutes. To be exact, the ACS550 heavy duty ratings allow for 150% short term overload ratings from 1 to 10 minutes. Since we aren’t always able to know the application our customers are implementing these drives into all ratings at our site are specified at heavy duty.

The ACS800 variable frequency drive is a newer product for those looking for a possible replacement or upgrade of their ACS550 drive. The ACS800 is defined by us as an applications drive. This drive has just about every feature a modern variable frequency drive can have. This includes the integration of a full range of applications and extensive quantity of accessories to make it compatible with almost any industrial system. For the longest time the ACS800 has been ABBs go to drive.
