摘要： The drive of the motor is stopped, the electromagnetic switch contacts are switched OFF, and thereafter the first and second contact points are closed to form a closed circuit of the smoothing capacitor, second contact point, first and second resistors, motor coil, ground 1, ground 2, first contact point, and smoothing capacitor. Charging voltage of the smoothing capacitor is applied to the closed circuit. If an insulation resistance of the motor deteriorates, a current flowing through the closed circuit is increased. The increase of the current is detected by means of the potential difference across the first resistor R1 in the closed circuit, to detect insulation resistance deterioration of the motor.

摘要： An insulation-resistance degradation detecting device capable of selecting one of a plurality of motors and detecting its insulation-resistance degradation. A power source unit is connected with a plurality of motor drive amplifiers which drive two motors, individually. The motor is selected by selecting means, and a contactor S1 or S2 is turned on. When a smoothing capacitor C of the power source unit reaches a predetermined voltage after an electromagnetic contactor is turned off, contactors SW1 and SW2 are turned on, whereupon one end of the smoothing capacitor C, contactor SW2, resistors R1 and R2, contactor S1 or S2, coil of the motor, insulation resistor Rx of the motor, grounds G2 and G1, contactor SW1, and the other end of the smoothing capacitor C form a closed circuit. The voltage of the smoothing capacitor C is applied to this closed circuit. A potential difference across the detection resistor R1 is obtained and compared with a reference voltage to detect insulation-resistance degradation. The single insulation-resistance degradation detecting device can detect insulation degradation of the plurality of motors, so that a space-saving configuration can be obtained at low cost.

摘要： While the motor drive amplifier is not operating, electromagnetic switch contacts are held closed for a predetermined period of time, three-phase power is rectified by a rectifier circuit and a smoothing capacitor is charged. Then, the smoothing capacitor is discharged through a discharging resistor and, when a predetermined voltage is reached, a contact is closed, with the result that a closed circuit is formed by the smoothing capacitor, a detection resistor, a motor coil, motor insulation resistance, and ground. A voltage generating across the detection resistor due to leakage current is detected and compared with a reference value. If the detected voltage exceeds the reference value, an insulation degradation signal is delivered.
