These are variable speed drive/controller systems and controllers. They vary the speed of a DC motor by adjusting the amount of power supplied to the motor. This can be done in a variety of ways, but the most common method is to use a phase-controlled rectifier bridge. The bridge will conduct current only when the power line voltage exceeds the voltage across the motor terminals. The power to the motor can therefore be controlled by varying the point at which the bridge starts to conduct, relative to the phase of the line voltage.
