Stator mechanism for magnetic levitation motor, and stator coil

Abstract

A stator mechanism for a magnetic levitation motor and a stator coil. The stator mechanism includes a stator coil and a stator core. The stator core includes a stator yoke and at least one pair of stator teeth (). Each of the stator teeth () includes a vertical section () contacted with the stator yoke and a transverse section () at a predetermined angle with the vertical section (). The stator coil includes an insulating framework () and a coil (). The insulating framework () includes an insulating body () disposed on an outer surface of the vertical section (). The insulating body () has a first end and a second end opposite to each other in a first extending direction. The first end is provided with a first baffle (), and the second end is provided with a second baffle (). The insulating body () has a first main surface () and a second main surface () opposite to each other. The second main surface () is a cambered surface protruding outwards away from the first main surface (). The coil () is transversely wound on the first main surface () and the second main surface () and tightly attached thereto. When a cross-section of the wound coils is of specific shape, coils can be stacked to a maximum density in a limited space.
