Embodiment 1
[0047] The printed asynchronous motor is composed of rotor core b1, rotor printed board b3, air gap c, stator printed board d, stator core e, bearing f, stator insulating paper g, rotor insulating paper b2, along the two shaft gears The rotating shaft a is sequentially composed of rotor core b1-rotor insulating paper b2-multi-layer rotor printed board b3-rotor b-air gap c-multi-layer stator printed board d-stator-stator insulating paper g-stator core e - The arrangement of the bearings f.
[0048] The multi-layer stator printed board d is fixed on the stator core e through the installation and positioning holes, and multiple radial conductors are evenly distributed on each layer of the printed board, and a via hole is set at both ends of each radial conductor, and all layers are the same The positional radial conductors are connected in parallel with copper pillars using via holes, and the three-phase windings share the parallel radial part. The number of layers of the stator...
