Motorcycle Magneto Stator Coil manufacturers tell you that if there is a generator, there is a motor, and if the motor has a rotor, there is a stator. Of course, there is a rotor permanent magnet synchronous motor and a stator permanent magnet synchronous motor.
The Motorcycle Magneto Stator Coil manufacturer tells you that to talk about the stator permanent magnet synchronous motor, you have to mention the rotor permanent magnet synchronous motor first. The main difference between the two structures is whether the permanent magnets are installed on the stator side of the rotor side.

The Motorcycle Magneto Stator Coil manufacturer tells you that we know that in the traditional rotor permanent magnet motor, the permanent magnet is located on the rotor side of the motor, and the motor industry can also divide it into 4 basic structures according to the position of the permanent magnet: 1) Surface mount; 2) Embedded; 3) Radial embedded; 4) Tangentially embedded. It is well known that rotor permanent magnet motors have higher power density and efficiency than traditional DC motors and asynchronous motors.
However, Motorcycle Magneto Stator Coil manufacturers tell you that rotor permanent magnet motors usually require special reinforcement measures to the rotor to overcome the centrifugal force at high speed, such as installing sleeves made of non-metal fiber materials or stainless steel, etc. The consequence is that it not only leads to a more complex structure and higher manufacturing cost but also increases the equivalent air gap and reduces the performance of the motor.
At the same time, the Motorcycle Magneto Stator Coil manufacturer tells you that the permanent magnets are placed on the rotor, which will make it difficult to dissipate heat, and the resulting temperature rise of the motor may cause irreversible demagnetization of the permanent magnets, limiting the output of the motor and reducing the power density of the motor, etc.
The above information is motorcycle Magneto Stator Coil Manufacturer's introduction and analysis of the difference between rotor permanent magnet, hope it helps you.
