Servo Motor Repairs

Servo motor repairs are less expensive and quicker than servo motor replacements. Servo motor repairs should be taken with extreme caution and only be performed by technicians who have training and experience to work with electrical equipment. Most companies who offer servo motor repairs do not even perform the repair in their facility; instead, these companies outsource the repair to […]

Allen Bradley VFD Repair

Allen Bradley VFD repair is less expensive and quicker than Allen Bradley VFD replacement. The most economical way to get an Allen Bradley VFD repair is by going directly to an Allen Bradley VFD repair center such as Precision Electric, instead of using a local vendor who doesn’t even perform the VFD repair themselves. Precision Electric performs all Allen […]

Cutler Hammer VFD

Cutler Hammer VFD drives can reduce energy consumption from 10 to 50 percent by adjusting the speed of its corresponding electric motor to its needed output. Cutler Hammer VFD drives allows for steady speed error, fast torque rise time, high immunity to resonance vibrations and high starting torque and current. Cutler Hammer VFD drives can be customized […]

AC DC Industrial Electric Motors

AC DC industrial electric motors operate by applying alternating current (AC) or direct current (DC) power to its corresponding AC or DC motor. AC DC industrial electric motors are seen in manufacturing equipment and other industrial rotating machinery. The main parts of an AC electric motor are the stator and rotor. The AC electric motor stator consists […]

ABB Drive Repair

ABB drive repair is less expensive and has a quicker turnaround time than ABB drive replacement. ABB will sometimes recommend replacing failed drives instead of repairing them but ABB drive replacement is very expensive. Checking the motor and drive terminal connections is a step many people miss or do incorrectly during an ABB drive repair. […]

VFD Device

A VFD device is also known as Variable Frequency Drive, variable speed drive, adjustable speed drive, electronic motor controller, or an inverter. A VFD device is a solid state electric motor control system designed to control the speed of an electric motor. VFD devices operate as load controls within electric motor applications; and a VFD device can […]

How Do VFDs Work

How Do VFDs Work? A variable frequency drive is also known as a VFD, variable speed drive, adjustable speed drive, electronic motor controller, or an inverter.  How do VFDs work? Every VFD is unique with its own component characteristics so how each VFD works is dependent upon components within the VFD. Most VFDs integrate a solid […]

Magnetek VFD Repair

Most Magnetek VFD repair can be prevented with routine maintenance. Magnetek VFD repair costs and lead times can also be reduced with routine maintenance. Magnetek VFD repair can be expensive and also cost manufacturers production downtime while the Magnetek VFD repair is in process. Most manufacturers stock spare Magnetek VFD modules to prevent production downtime in the event of […]

Eaton Overcurrent Protection

Eaton overcurrent protection and  Eaton current control for the Eaton 9000X drive is based on motor current measurement in all three phases. In the Frame 9/ Chassis 61 Eaton drives, the current sensors are built into the IGBT SKIP modules, and the current signals are combined and fed into a 14-bit A/D converter on the lower […]

Eaton Low Voltage Drives

Eaton low voltage drives (also known as variable frequency drives) adjust an electric motor’s speed to closely match output requirements, resulting in a typical energy savings of 10 to 50 percent. Eaton’s SVX9000 adjustable frequency drive offers sensorless vector control technology coupled with an adaptive motor model and sophisticated ASIC circuit features. This technology allows […]

Lenze Frequency Inverter

Lenze frequency inverter drives are used in a wide variety of industries including materials handling, packaging, robotics and automotive. Lenze frequency inverter products are carefully coordinated and matched and can be combined as required to provide the right solution for most needs. Lenze frequency inverter drives combine reliability with quality to enable Lenze to help increase the productivity […]

What Is A VFD?

VFD is an abbreviation that stands for Variable Frequency Drive. VFD’s are also known as variable frequency drives, variable speed drives, adjustable speed drives, electronic motor controllers, or inverters. VFD’s are solid state motor control systems designed to control the speed of an AC (alternating current) electric motor. Variable frequency drives operate as load controls within AC electric […]
