Title:
MOTOR CONTROL DEVICE
Document Type and Number:
WIPO Patent Application WO/2013/077407
Kind Code:
A1
Abstract:
A temperature sensor (Sa) for detecting the temperature (Tc) of the motor coil of a motor (6) is disposed on said motor coil. Multiple threshold values are set with regard to the temperature (Tc) detected by means of the temperature sensor (Sa), current restriction conditions that are different from one another are set for each temperature region divided by means of each threshold value, and a motor current restriction means (95) restricts the current value of the motor (6) in accordance with the current restriction condition of the temperature region containing the detected temperature (Tc). As a consequence, the temperature of the motor is managed without preventing a vehicle from being driven.
