Title:
ELECTRIC DISC BRAKE DEVICE
Document Type and Number:
Japanese Patent JP3899489
Kind Code:
B2
Abstract:
PROBLEM TO BE SOLVED: To provide an electric disc brake device capable of preventing the deterioration of a motor coil and an insulating film by properly detecting the temperature of a motor.
SOLUTION: NTC thermistors 95U, 95V and 95W mounted on a U-phase coil 70U, a V-phase coil 70V and a W-phase coil 70W are connected in parallel, and temperature information of the NTC thermistors 95U, 95V, 95W of each phase are transmitted to a comparator 91 inside of a vehicle through a first outgoing line 89a and a second outgoing line 89b to prevent the overheating of the motor 12. As the prevention of overheat of the motor 12 is achieved by using only two outgoing lines (first outgoing line 89a and second outgoing line 89b) from a temperature sensor (NTC thermistor 95) with respect to a controller 62, the outgoing lines can be easily deflected, the generation of disconnection can be prevented, and further the outgoing lines can be easily led.
