For applications that require faster deceleration rates, or where motor speeds are exceeding the synchronous speed set by the output frequency of the drive (an overhauling load condition), a braking resistor is required. Braking resistors increase the braking

Potentiometer as a Rheostat | DC Circuits | Electronics ...

This simple method of motor speed control, however, is inefficient, as it results in substantial amounts of power being dissipated (wasted) by the rheostat. A much more efficient means of motor control relies on fast "pulsing" of power to the motor, using a high-speed switching device such as a transistor.
