[0002] An interior permanent magnet synchronous motor (IPMS) is a device that uses electromagnetic principles to convert mechanical work. Its basic principle is to convert electrical energy into mechanical energy through the interaction between magnets and coils. In an IPMSM, the magnets are permanent magnets, while the coils are the windings on the motor's stator. IPMSMs offer high efficiency, high reliability, and a wide speed range, making them valuable in a variety of applications, including automotive, industrial, and renewable energy. With continuous technological advancement and innovation, IPMSMs will have even broader development prospects.
