IPM (Interior Permanent Magnet)

A type of motor that has a rotor embedded with permanent magnets is called the IPM (interior permanent magnet) type. Compared with the SPM (surface permanent magnet), this type of motor can reduce the risk of a magnet being peeled off by centrifugal force, and take advantage of reluctance torque. The IPM type allows various structures for embedding permanent magnets.
