Abstract
PURPOSE: To prevent a compact light-weight motor from overheating even if it is used under tough conditions.
CONSTITUTION: When the armature 3 of the DC motor for driving an elevator gondola stops, a current for compensating the weight difference between the gondola and a counterweight is supplied to the armature 3 to keep the starting torque raised. The outputs of voltage detectors 6a, 6b, which detect the voltages of the armature 3 and an auxiliary electrode 5, are entered into a temperature rise detection circuit 6. The circuit 6 compares the outputs of the voltage detectors with setpoints. When the output exceeds the setpoint, the circuit 6 generates an output signal. When the gondola is stopped and a running relay contact 7 is closed and the temperature rise detection circuit operates, a runnig control relay 8 is energized to keep the armature from operating.
