Abstract:
A motor control device includes coil temperature detection means, cooling oil temperature detection means, and a control unit. The control unit implements a coil protection torque restriction and a cooling oil protection torque restriction. The control unit makes it easier for the coil protection torque restriction to be preferentially implemented in a low rotation operating region in which a motor operates at a low rotation speed equal to or lower than a predetermined value, and makes it easier for the cooling oil protection torque restriction to be preferentially implemented in a high rotation operating region in which the motor operates at a higher rotation speed than in the low rotation operating region.
