ABSTRACT:
A speed selection control is provided for a DC electric accessory motor having an armature winding and being mounted on a vehicle having a high reactance, multiphase alternator with a diode bridge rectifying output circuit, a battery connected across the output circuit and a voltage regulator controlling the voltage across the output circuit to a substantially constant voltage. One end of the motor armature winding is connected to the ungrounded end of the output circuit, and the other end of the motor armature winding is connected to the junctions of the diodes of each phase of the output circuit through a plurality of switched rectifiers, each having an anode connected to the other end of the motor armature winding and a cathode connected to the junction of the diodes of one phase of the output circuit. A switch control provides a continuous activation signal to selected numbers of the switched rectifiers, so that the motor armature receives electric power from the alternator in a substantially rectangular voltage wave with duty cycle determined by the number of switched rectifiers activated and thus the number of alternator phases used.
