The pump rotor magnet is the part of the pump used to generate a magnetic field. During the operation of the pump, it works with the stator magnet to achieve the flow of water through the magnetic field generated by the current.
Pump rotor magnet is usually composed of a plurality of magnets, these magnets are usually made of ferrite or NdFeb and other magnetic materials, usually known as magnet ring rotor, when the current through the stator magnet, the pump rotor magnet will also be driven, thus creating a rotating magnetic field. This rotating magnetic field pushes the water forward and causes the pump to work. In this process, the magnet ring rotates at a certain speed, but also performs vibration and friction effects.

In order to ensure the performance and life of the rotor magnet, it needs to undergo certain surface treatment and magnetic field optimization. Common treatment methods include coating anticorrosive layer and adjusting the direction of magnetization. At the same time, ndFeb magnetic material also has high thermal stability and magnetization, can withstand high working temperature and magnetic field strength, so as to ensure the performance of the pump.
In general, pump rotor magnet is a very key component in the pump, its performance and stability are directly related to the running efficiency and service life of the pump.
