Abstract

The invention relates to the field of motors, and provides a motor temperature protection device, a motor, an electric vehicle and a control method. The temperature sensor of the motor temperature protection device detects the temperature of the motor in real time and transmits the detected temperature signal to the control circuit for comparison. The prompting signal causes the prompting device to perform a prompting action to prompt the user of the current running state of the motor. When the user receives the prompt action, he can take relevant safety measures such as slowing down, driving the electric motorcycle or electric bicycle aside, so as to avoid damage to the motor and safety accidents. Therefore, the motor temperature protection device and control method provided by the present invention can solve the problems in the prior art that the electric motors of electric motorcycles and electric bicycles run under the condition of excessive temperature, causing damage to the electric motors and potential safety hazards.

Description

technical field [0001] The invention relates to the field of motors, in particular to a motor temperature protection device, a motor, an electric vehicle and a control method. Background technique [0002] The electric motor is one of the three core components of the electric vehicle, and its basic performance is related to the overall performance of the electric vehicle. The use environment and operating state of the electric motor on the electric vehicle are complex and changeable. When the environment and operating state change, the temperature inside the electric motor will also change accordingly. At this stage, electric motorcycles and electric bicycles mostly use DC brushless permanent magnet motors. If the motors run for a long time in a state of high temperature, it is easy to cause demagnetization of the permanent magnets of the motors and damage to the winding insulation materials, which will lead to performance degradation or even failure of the motors. Affect t...
