Stepper Motor Controller

A stepper motoris a brush-less Direct Current electric motorthat divides a full rotation into a number of equal steps. The stepper motor’s position can then be commanded to move and hold at one of these steps without any feedback sensor via an open-loop stepper motor controller as long as the stepper motor is carefully sized to the application.

Stepper Motor System Overview

Motion Control, in electronic terms, means to accurately control the movement of an object based on either speed, distance, load, inertia or a combination of all these factors. There are numerous types of motion control systems, including; Stepper Motor, Stepper Motor Controller, Linear Step Motor, DC Brush, Brush-less, Servo, Brush-less Servo and more. This post will concentrate on Step Motor technology.In Theory, a Stepper motor is a marvel in simplicity. It has no brushes, or contacts. Basically a stepper motor is a synchronous motor with the magnetic field electronically switched to rotate the armature magnet around.A stepper Motor Controller System consists of three basic elements, often combined with some type of user interface (Host Computer, PLC or Dumb Terminal).

Stepper Motor ControllerA stepper motor controller is usually, but not exclusively, done in an open loop configuration. The rotor position of the stepper motor is assumed to follow a controlled rotating field. Because of this, precise positioning with stepper motor is simpler and less expensive than closed loop stepper motor controls.Modern stepper motor controllers drive the motor with much higher voltages than the motor nameplate rated voltage, and limit current through chopping. The usual setup is to have a positioning stepper motor controller, known as an indexer. The indexersends the step and direction pulses to a separate higher voltage drive circuit which is responsible for commutation and current limiting.

Direct Current brush motors rotate continuously when voltage is applied to their terminals. Stepper motors and stepper motor controllers, on the other hand, effectively have multiple “toothed” electromagnets arranged around a central gear-shaped piece of iron. The electromagnets are energized by an external control circuit, such as a stepper motor micro controller. To make the stepper motor shaft turn, one electromagnet is given power, which magnetically attracts the gear’s teeth. When the gear’s teeth are aligned to the first electromagnet, they are slightly offset from the next electromagnet. So when the next electromagnet is turned on and the first is turned off, the gear rotates slightly to align with the next one, and from there the process is repeated. Each of those rotations is called a “step”, with an integer number of steps making a full rotation. In that way, the motor can be turned by a precise angle.

AC Tech VFD customers engage in demanding applications and their expectations from their suppliers are unyielding.

VFD Motor Control Overview

A three phase asynchronous motor convertselectrical energy into mechanicalpower and can also function as a generatorat the same time. The rated speed ofthe motor is determined by the numberof pole pairs. 4-pole motors are the mostfrequently used type (1500 rpm at50 Hz), but 2 and 6-pole motors are alsosometimes encountered.A magnetizing current needs to startflowing when the motor is in the idlestate so that a magnetic field can begenerated. As soon as the motor goes on load,the motor speed drops in relation tothe no-load speed. An AC Tech VFD can be used to compensate for this phenomenon,which is termed slip, via itscontrol function, e.g. VFD vector control.If the rated speed is exceeded,operation can continue but will be subjectto reduced torque (field weakeningrange).The basic dimensions of the motor,such as the shaft diameter, flange diameterand foot height, are standardized.Various built-on accessories (e.g. brake,encoder, blower) can be used to adapt themotor to suit the relevant VFD task.

Industrial Inverters

Industrial InvertersIndustrial inverters are also known as variable speed drives, variable frequency drives, VFD’s, and adjustable speed drives. Industrial inverters are solid state motor control systems used mainly for industrial manufacturing. Variable speed drives are designed to control the speed of an electric motor. Variable speed drives can reduce energy costs up to 50% by speed reduction on applications where the full speed (RPM) of the electric motor is not required.

The energy saved on a utility bill from using an industrial inverter is often significant enough to pay for the inverter within a couple of months from installation date. Industrial inverters are commonly used on pump, fan, and air compressor applications, and are often put into production at manufacturing facilities to increase or decrease the start up time on alternating current (AC) electric motors.

Increasing and/or decreasing the start up time on an AC electric motor via an inverter can add years to the motor’s overall lifespan. Using an industrial inverter can also improve efficiency on production demands. Industrial inverters provide the ability to control the frequency of starting and stopping an AC electric motor.This motor control capability provides a means by which an AC electric motor is only operating when needed. AC electric motors have a longer lifespan if they are not continuously operating when they do not need to be.

Types of Industrial Inverters

The most common type of industrial inverter is known as a V/Hz (volts per hertz), and are applied to applications such as fans, pumps, air compressors, and other related applications wherehigh starting torque is not required; V/Hz industrial inverters are also used on applications where full torque is not required when operating an electric motor lower than the motor’s rated speed (RPM). V/Hz industrial inverters are the most inexpensive type of industrial inverters. When choosing an industrial inverter it is crucial to remember that V/Hz inverters DO NOT provide full motor torque at low motor RPM.

Industrial InvertersOpen-Loop vector inverters are also known as “sensorless vector” inverters. Open loop vector inverters adapted the name “sensorless vector” because they do not use an external encoder for speed feedback to the motor for precise speed regulation. Open loop vector inverters are used in applications where high starting torque and full torque at low motor speed (RPM) is required. Open-Loop vector inverters operating a motor at zero RPM should not be used on crane or hoist applications. Most open-loop vector industrial inverters are used on CNC machines, mixers, mills, lathes, and other applications where high starting torque or full torque at low RPM is needed.Open loop vector inverters are usually more expensive than a V/Hz industrial inverters.

Closed-Loop vector industrial inverters are used in applications where precise speed regulation (0.01%) is needed, or in applications where extensive programming is needed. Closed-Loop vector inverters use an encoder on the electric motor to provide constant shaft position which sends a signal to inverter’s microprocessor. The encoder feedback allows the drive microprocessor to constantly control torque no matter how many RPM the motor is operating at. Closed-Loop vector industrial inverters are used to provide the motor to operate at full torque even at zero RPM. Closed-Loop vector inverters are commonly used on hoist and crane applications because crane and hoist motors must produce full torque prior the motor’s brake being released, otherwise the load will drop and the electric motor will not be able to stop.
