Description

technical field [0001] The invention relates to a three-rotor motor in the technical field of motor equipment, in particular to a three-rotor motor with axial magnetic flux leakage prevention, and also to an assembly method of the three-rotor motor. Background technique [0002] The excitation winding on the rotor of the motor is equivalent to many independent electromagnets. The essence of the motor is to rotate the center after the interaction between the electromagnet and another electromagnet or permanent magnet. It is found through experiments that the magnetic energy of the electromagnet cannot be In the long-distance series connection in the iron core, the electromagnet and the permanent magnet not only have the centering property of the north and south poles, but also have the centering property of the side stage between the north and south poles. The two adjacent electromagnets on the stator of the motor cannot connect the magnetic energy in series when doing work. ...
