10 - Electric Motors
... When power is applied, DC motors turn in one direction at a fixed speed. They are optimized to run at a fixed, usually high RPM. Torque is highest at the rated speed and lowest at low speeds. Speed can be varied if a (pulse width modulation) PWM controller is added. ...

... Have you find that electrical devices become warm after long run. If yes;do you know why the electrical devices become warm after long run? When a potential difference or Voltage is applied across the ends of a conductive metallic wire, the free electrons begin forced to move. When the electrons mov ...
