It is estimated that the average car has around 80 electric motors - many due to motorists’ insatiable demand for greater comfort and convenience. In a top-range Mercedes-Benz, for example, there are ...

An H-bridge (full-bridge) driver is quite popular in driving loads such as brushed DC motors and it is widely used in robotics and industry. The main advantages of using an H-bridge driver are high ...

[Frank Herrmann] had an interesting idea to turn a geared DC motor into a servo motor assembly, but with a stepper motor-like interface. By stacking some small PCBs behind the motor body, it was ...

With no need for compressed air, early electric actuators could operate with less sound and less maintenance than the predominant pneumatic actuator. Of course, the standard pneumatic option offered ...

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 ...

For motor applications, engineers have several options at their disposal. Typically, engineers can choose between direct-current (DC) or alternating-current (AC) motors. Machine Design has covered the ...

The wide range of electric motors can be a confusing topic even without considering intelligent motor control. This brief overview is for those who think motors are only divided into two categories: ...

Brushless-dc motors are taking center stage in medical-equipment design because they last twice as long a competing technologies. • Sensorless brushless-dc-drives have evolved to a point where they ...
