Description :

A motor drive controls the speed torque direction and resulting horsepower of a motor dc drives typically control a shunt wound dc motor which has separate armature and field circuits. Velmex vxm systems enable the step motor to operate more efficiently by utilizing pulse width modulation current control with an automatic motor power down for lower power consumption the systems microprocessor is in total control of the voltage level on each phase of the motor drive which eliminates the noise interference. This article presented an understanding of what dc motor controllers are and how they work for more information on related products consult our other guides or visit the thomas supplier discovery platform to locate potential sources of supply or view details on specific products. While representing from near zero to perhaps 2 of the pump population we now believe canned motor pumps cmps are probably applicable to 50 of the pumps at a typical refinery site there are of course restrictions ie thermal shock dry running slurries etc which in most cases can be handled by engineering controls. Motor controllers and drives are electrical or electronic devices that regulate motor speed torque and position outputsthe drive modifies the power input to the motor to achieve the desired output the controller circuits are commonly integrated with the drive circuits as one stand alone unit thus the terms motor drive and motor controller are frequently used interchangeably
