Description
technical field [0001] The invention relates to the technical field of electromagnetic drive, in particular to an electromagnetic motor. Background technique [0002] The rotor and stator in the existing switched reluctance motor are made of stacked silicon steel sheets; after the coil winding on the stator convex stage is energized, the rotor made of stacked silicon steel sheets is driven to rotate by using the electromagnetic mutual inductance to generate torque. The electromagnetic field generated after the stator convex coil winding is energized forms an electromagnetic eddy current in the silicon steel sheet of the stator and rotor, and the magnetic loss generates a large amount of heat, which causes the rotor to be deformed by heat and affects the dynamic accuracy, reliability and service life of the rotor during operation. Light weight, small moment of inertia, high strength, high rigidity, eddy current, small magnetic loss, and good thermal stability The motor rotor ...
