This is a very cool electronic project to control dc loads using a very cheap and reliable design. This video also explains ...

In the ac-induction motor-control system in Figure 1 , the servo loop is a PWM drive circuit. The circuit switches the MOSFETs, which in turn send current through the legs of the ac motor. A typical ...

This pwm motor controller is using the fact that the small dc motor has the revolution speed depending on the power supply voltage. In this circuit the discharge time can be adjusted between 0.2ms and ...

In order to drive the motor, the control electronics generate three low-frequency sinewaves, 120 degrees apart, which modulate the carrier pulses to each pair of switches.

It features adjustable maximum speed, minimum speed, current limit, I.R. compensation and acceleration, plus a quiet ...

Miniature drills are used in medical applications but they have very particular requirements. They must not produce carbon dust or electrical sparks. But more importantly they need to be controlled ...
