Title:
MOTOR CONTROL DEVICE
Document Type and Number:
WIPO Patent Application WO/2018/142952
Kind Code:
A1
Abstract:
In order to appropriately restrict a current output from an inverter to a motor according to the state of a cooling mechanism that cools the motor or the inverter, this motor control unit 100 is provided with: a current command unit 150 which calculates current command values (Id*, Iq*) for determining a current output to a motor 310 on the basis of an input torque command; a motor lock determining unit 170 which determines whether the motor 310 is in a lock state on the basis of the motor rotation speed Nrpm indicating the rotation state of the motor 310; and a torque command restricting unit 160 which, when the motor 310 is determined to be in the lock state by the motor lock determining unit 170, restricts the current output to the motor 310 by restricting the torque command on the basis of a cooling water temperature Tc indicating the state of the cooling mechanism.
