External Rotor PMSM Drive Drum

95% Efficiency External Rotor PMSM Drive Drum

Permanent magnet pulley drive

unique external rotor permanent magnet technology, Jiaxuan permanent magnet direct drive roller shaft is fixed, which is equivalent to the stator part of the motor. The stator core is superimposed and fixed on the shaft by silicon steel sheets, where the stator winding is embedded. When the stator winding passes three-phase symmetry The alternating current can generate a rotating magnetic field; the surface of the drum barrel is equivalent to the rotor part of the motor. The rotor is superimposed and fixed on the inner surface of the barrel by silicon steel sheets. UH-grade NdFeB permanent magnets are embedded in it, which will generate a permanent static magnetic field. After symmetrical three-phase alternating current, the motor works, that is, the drum works.

The innovation points

1. Permanent magnet motor technology
