DC motor drives are the interface between a controller and a DC motor. Their job is to convert speed and direction input from the controller to currents and voltages compatible with the motor. There ...

DC Motors were king in industry up until the late 1980s; These motors were popular because they were able to run to a variable speed setpoint, and they could run at full torque from stall to base ...

The way we control the speed of fan motors or pump motors has tremendously changed in the past two decades with the introduction of variable-frequency drives (VFDs), aka variable-frequency controllers ...

Speed, torque, and horsepower are three inter-related parameters in motor control. The speed of a motor, measured in revolutions per minute (rpm), defines a motor's ability to spin at a rate per unit ...

The topic of motors and motor control techniques is wide and varied. Part one of this two-part article will cover the principles of alternating-current (AC) motor operation and control. Part two will ...

Special algorithms make ac induction motors respond like variable-speed dc motors for fast PID control. Synchronous dc motors often top the field in high-performance motor controls. This group of ...

BOHEMIA, N.Y., 4 Aug. 2014. Data Device Corp. (DDC) in Bohemia, N.Y., is introducing the PW-82560N0 speed and torque brushless DC electric motor controller for military applications such as gun ...
