For motors controlled by a variable frequency drive (VFD), the control method used in large part determines a motor’s efficiency and performance in an application.

Field oriented control (FOC) is a high-performance technique for motor control that is becoming increasingly attractive for all kinds of applications. It's worthwhile, therefore, for developers to ...

That’s basically everything except speed control of the motors. There are so many ways to control the speed of DC motors, but an easy way is to use pulse-width modulation. Here, applying a PWM signal ...

Rotational Speed When you write software to control a stepper motor, you must first know how many pulses the motor needs to turn a full rotation.

When Tesla first introduced the 3-phase alternating current (AC) induction motor in 1888, he knew that his invention was more efficient and reliable than Edison's direct current (DC) motor. However, ...

Ideally, a motor driver for a brushed dc motor should also include a current-limiting function and may need to support a high-speed drive.
