Description
技术领域technical field

However, the motor will generate heat when it is continuously working. The inner cavity is sealed, which causes the internal gas to expand, the internal pressure rises and the body ruptures, and even under extreme conditions, the high temperature heat causes the motor to burn out. In order to avoid the above situation, it is necessary to design a ventilating structure for the motor, so as to adjust the pressure in its inner cavity, but it is necessary to ensure its waterproof and sealing performance.
现有技术中存在在电机上设置电控阀门的设计，通过配合传感器对温度、压力等参数进行监控，一旦检测值异常，即控制阀门开启，达到泄压的目的，当检测值正常时，再控制阀门复位关闭。此种结构系统较为复杂，对传感器灵敏性要求较高，故障率大，防浸水能力差，且对电机结构改造程度大，适配性不足。In the prior art, there is a design of setting an electronically controlled valve on the motor. By cooperating with sensors to monitor parameters such as temperature and pressure, once the detected value is abnormal, the valve is controlled to open to achieve the purpose of pressure relief. The control valve resets to close. This kind of structural system is relatively complex, requires high sensor sensitivity, high failure rate, poor anti-immersion ability, and the degree of structural modification of the motor is large, and the adaptability is insufficient.
