The magnet and impeller of the brushless DC magnetic drive pump are injection molded to form the rotor of the motor. There is a shaft sleeve directly injection molded in the middle of the rotor, which is fixed in the shell through a high-performance ceramic shaft. The stator and circuit of the motor

The board part is potted with epoxy resin in the pump body, and there is a thin wall between the stator and the rotor, and there is no need to match the traditional mechanical shaft seal, so it is completely sealed. The torque of the motor is through the silicon steel sheet (stator)

After the coil is energized, a magnetic field is generated to drive the permanent magnet (rotor) to work. The magnet is magnetized in n (n is an even number) stage, so that the magnet parts form a complete coupling magnetic system. When the magnetic poles generated by the stator coil

The magnetic poles of the magnet are opposite to each other, that is, the displacement angle between the two magnetic poles Φ=0 , at this time the magnetic energy of the magnetic system is the lowest; when the magnetic poles rotate to the same pole, the displacement angle between the two magnetic poles Φ=2π/n , Now the magnetic system

The maximum magnetic energy. After removing the external force, since the magnetic poles of the magnetic system repel each other, the magnetic force will restore the magnet to the lowest magnetic energy state. Then the magnets move, driving the magnetic rotor to rotate.
