The invention relates to an electromagnetic load separation type axial field permanent magnet motor, comprising two armature stators, a middle permanent magnet stator and two rotors, two armature stators, a permanent magnet stator and two rotors according to the first The order of the armature stator, the first rotor, the permanent magnet stator, the second rotor, and the second armature stator are arranged coaxially along the axial direction, the first armature stator and the second armature stator are exactly the same, the first rotor and the second The two rotors are identical, and the armature stators include armature stator cores and armature windings. The permanent magnet stators include permanent magnet stator cores, high coercivity permanent magnets and permanent magnet stator brackets made of non-magnetic materials. The rotors each include a rotor core and a rotor bracket made of non-magnetic material. The electromagnetic load separation type axial field permanent magnet motor solves the problems of the existing stator permanent magnet type axial field permanent magnet motor with narrow stator tooth width and relatively thin iron core yoke, improves the output capacity of the motor, and reduces the power consumption of the motor. vibration and noise.
Description
technical field [0001] The invention relates to an electromagnetic load separated axial magnetic field permanent magnet motor, which belongs to the field of axial magnetic field permanent magnet motors. Background technique [0002] Stator permanent magnet axial field permanent magnet motors such as flux switching axial field permanent magnet motors, flux reverse axial field permanent magnet motors, and double salient axial field permanent magnet motors have been deeply studied since their inception. Its strong fault tolerance, wide speed regulation, high reliability and other advantages prove that it has a wide application prospect. Stator permanent magnet axial field permanent magnet motor adopts double salient core structure and fractional slot concentrated short-distance winding. The time and space harmonic distribution of air gap radial electromagnetic force wave is the same as that of traditional induction motor and rotor permanent magnet Motors etc. are different. I...
