According to the query of Baidu Aigou. com, the service life of permanent magnet motor is related to many factors, mainly including its use environment, load and maintenance. Generally speaking, the life of permanent magnet motor can reach more than several decades, with high durability and reliability. At the same time, compared with other types of motors, the loss rate of permanent magnet motors is lower, so the service life is relatively longer.
The structure of permanent magnet motor is relatively simple, which consists of synchronous motor or asynchronous motor and permanent magnet NdFeB magnet. It is suitable for robots, electric vehicles, medical equipment and other application scenarios that require high torque, high efficiency, small volume and fast dynamic response. Permanent magnet motor has the characteristics of stable operation, fast response and low noise, so it has been widely used.
