Title:
MOTOR CONTROL DEVICE
Document Type and Number:
WIPO Patent Application WO/2012/042788
Kind Code:
A1
Abstract:
This motor control device has a dynamic brake function of absorbing the energy of a motor to apply a brake to the motor. The motor control device comprises: a dynamic brake resistor; a thermal switch which is arranged adjacent to the dynamic brake resistor; a thermal fuse which is arranged adjacent to the dynamic brake resistor and is connected to the dynamic brake resistor in series; and a disconnection detection circuit which detects the state of disconnection in the thermal switch. In the motor control device, the working temperature of the thermal switch is set at a temperature lower than the working temperature of the thermal fuse.
