In this paper, a detailed analysis on torque ripples of brushless dc drives in both commutation and conduction region is given. A new control strategy for the elimination of torque ripples in BLDC ...

Brushless dc (BLDC) motors are widely used in industrial and home applications, such as in HVAC blowers, because of their efficiency and cost advantage. Furthermore, sensorless control of BLDC motors ...

Bipolar stepper motors are used in many applications, from driving paper through a printer to moving an XY stage in industrial equipment. Typically, the motors are driven and controlled by inexpensive ...

Pulse width modulation is a form of signal communication that transposes a signal from analog to digital form. Analog signals with changing amplitude and frequency pass through a comparator and are ...

Adjustable-frequency drives have been billed as an energy efficient way to drive three-phase ac induction motors. Nevertheless, designers should understand that motors fed by inverter power experience ...

Allegro® MicroSystems, Inc. has announced a new DMOS dual full-bridge PWM motor driver designed to control two DC motors at currents up to 2.4 A. Capable of drive voltages up to 36 V, the Allegro ...
