Abstract

The invention discloses a new energy automobile driving motor, and effectively solves the problem that the motor cannot be effectively cooled by adopting an air cooling heat dissipation mode in the prior art, the new energy automobile driving motor comprises a temperature detection circuit, an automobile speed detection circuit and an output circuit, the temperature detection circuit detects a temperature signal of a motor through a temperature sensor U1, subtraction and comparison operation are conducted on the temperature signal, the vehicle speed detection circuit is started, and the vehicle speed detection circuit is used for detecting a vehicle speed signal of the new energy vehicle and conducting subtraction operation on the vehicle speed signal to obtain a comparison signal. The output circuit obtains a heat dissipation signal and an alarm signal by using the difference signal, and transmits the alarm signal to the ECU, thereby providing a better heat dissipation mode for the motor.

Description

technical field [0001] The invention relates to the field of new energy vehicle protection, in particular to a new energy vehicle drive motor. Background technique [0002] Studies have shown that the temperature of the motor affects the service life of the motor. The traditional method of detecting the temperature of the motor is to embed the temperature sensor inside the motor and obtain the temperature parameters through direct measurement. However, this method depends on the accuracy of the temperature sensor and the structure of the motor, and is limited by the number and installation position of the temperature sensor, so it cannot provide sufficient thermal protection for the motor. [0003] At present, most new energy vehicle motors use air cooling to dissipate heat through radiators (mostly cooling fans) or directly without radiators, that is, to dissipate heat through the air flow when the car is running. In the cooling mode, because the traditional motor temperat...
