Title:
モータ駆動装置及び冷凍サイクル適用機器
Document Type and Number:
Japanese Patent JP7150137
Kind Code:
B2
Abstract:
This motor drive device is provided with: an inverter (4) connected to a first motor (41) and a second motor (42) which have a permanent magnet in a rotor and driving the first motor (41) and the second motor (42); and current detection units (5, 6) for detecting a first motor current that is the motor current flowing through the first motor (41) and a second motor current that is the motor current flowing through the second motor (42). The inverter (4) drives the first motor (41) and the second motor (42) so that the current value of the motor current flowing through a motor to be controlled becomes small, said motor to be controlled being a motor having a larger current value between the first motor (41) and the second motor (42).
