While current control and PWM switching play the most direct role in driving brushless DC motors, the motion profile and position-control loop are also essential.

Open-loop stepper motors have held a prominent position in automation applications over the years due to their simplicity, excellent positioning, and low cost. However, as manufacturers utilize faster ...

Direct drives place rigorous demands on position-signal quality. Optimum measuring signals increase the quality of the machined workpiece surface, reduce vibration in the machine frame, stop excessive ...

3-phase BLDC motors are widely used in modern electronic devices such as hard, floppy and CD-ROM drives as well as other consumer and industrial equipment. BLDC motors have a straight-line, ...

The first type of motor built is still in widespread use In the late 1800s, several inventors built the first working motors, which used direct current (DC) power. After the invention of the induction ...

One of the more critical decisions engineers can make when designing any type of motion control process is choosing the motor. Getting the right motor, both in terms of type and size, is imperative to ...
