Title:
モータ制御装置
Document Type and Number:
Japanese Patent JP6680648
Kind Code:
B2
Abstract:
A motor control apparatus includes: an insulation resistance value detector that detects insulation resistance values of a plurality of motors; and a plurality of power supplies that output DC voltages, the plurality of power supplies being disposed as corresponding to the respective plurality of motors. The insulation resistance value detector, when detecting an insulation resistance value of a specific motor among the plurality of motors, applies the output voltage of the power supply corresponding to the specific motor to an earth, and applies the output voltage of another power supply to the motor corresponding to the other power supply to detect the insulation resistance value of the specific motor.
