Abstract
941,096. Control of D.C. motors. GENERAL MOTORS Ltd. Aug. 15, 1962 [Sept. 1, 1961], No. 31533/61. Drawings to Specification. Heading H2J. The bias on a transistor which is in circuit with a motor and a D.C. supply is adjustable by a variable resistance to change the motor armature voltage. The armature may be connected between a positive supply line and the transistor emitter, the resistance being connected to apply variable voltage to the base. A series motor has its field winding between the collector and the negative supply line, whilst, with a shunt motor, the collector is in parallel with the field winding. A compound motor has its series field winding between the collector and negative supply line or between the emitter and armature; the shunt field winding is between the positive supply line and collector or is connected directly between the supply lines. A resistance may be connected between the collector and negative supply line to protect the transistor from overload. A relay in series with the collector and series field winding short-circuits the emitter-collector circuit when the current reaches a predetermined value, to prevent overloading when the motor is stalled.
