ABSTRACT:
An armature mounted armature speed control system for a brushless repulsion motor of the type including a series of coil switches on the armature for shorting a succession of armature coils and detectors on the armature for operating each of the switches when the armature coil shorted by a switch is at a selected rotational position, the system comprising: a ring counter with sequentially energized output lines for receiving signals in sequence at a rate controlled by the reference frequency of count pules at the input of the counter, means for operating the switches in sequence by the counter created signals to control the speed of the armature at a set point and a selector switch shiftable upon receipt of a shift signal between a first condition with the signals from said counter operating the coil switches and a second condition with the detectors operating the coil switches.
