Permanent magnets and iron cores.
1. According to the patent search official website, the rotor of the in-wheel motor refers to the rotating part of the motor directly installed on the wheel. It is composed of permanent magnets and iron cores. Among them, the permanent magnets are made of high-performance permanent magnets. Made of magnetic materials, it has good magnetic properties and can generate a strong magnetic field to drive the motor to rotate. Therefore, the rotor of the wheel hub motor is made of permanent magnets and an iron core.
2. In-wheel motors are motors embedded in the wheel wheels. The stator is fixed on the tire and the rotor is fixed on the axle. When power is supplied, the stator and rotor move relative to each other.
