Cooling device used for motor and motor controller

Abstract

The invention embodiment discloses a cooling device used for a motor and a motor controller. The cooling device comprises a heat abstractor, a coolant pump, a motor controller control module and a data collection unit, wherein the data collection unit comprises a pressure sensor arranged at the water outlet of the coolant pump; the motor controller control module receives the collection data of the data collection unit, and the motor controller control module generates a corresponding motor control command through a preset control policy assembly according to the collection data; and the motor controller controls the opening and stopping of a motor according to the motor control command. In the embodiment, the motor controller control module can generate the corresponding motor control command when the coolant pump is in fault so as to control the opening and stopping of the motor, so as to avoid the problem that when the coolant pump is in fault, the motor continuously works under the condition that the coolant pump can not effectively cool the motor so that the temperatures of the motor and the motor controller are over high.

Description

technical field [0001] The invention relates to the field of automobile manufacturing, in particular to a cooling device for a motor and a motor controller. Background technique [0002] In various vehicles powered by new energy sources, the motor is used as a driving device to provide power. In order to solve the overheating problem of the motor and the motor controller during the working process, it is necessary to cool down the motor and the motor controller through a cooling device and an electric water pump. [0003] Such as figure 1 As shown, in the prior art, the cooling device of the motor and the motor controller includes an electric water pump 11 and a cooling device 12; After 13 is turned on, the electric water pump 11 and the cooling device 12 start to work; specifically, the electric water pump 11 pumps cooling water into the cooling pipeline 14, and the cooling water enters the cooling device 12 after absorbing the heat of the motor 15 and the motor controlle...

AI Technical Summary

Problems solved by technology

[0004] In practical applications, the electric water pump 11 may break down, which will cause the cooling device to fail. Since the motor 15 will continue to work at this time, the temperature of the motor 15 will continue to rise; The temperature of 15 and motor controller 16 is too high, and therefore burns out motor 15 or motor controller 16
