Abstract
A brushless motor stator comprising a lamination body in which conductive layers and insulating layers are formed alternately. A plurality of sets of coils of wound conductive patterns are formed on each conductive layer and the coils of the conductive layers adjoined via the insulating layers are connected to each other via through holes formed on the insulating layers.
Claims4
A motor comprising:
- a motor stator including a lamination body in which conductive layers and insulating layers are laminated alternately, a plurality of sets of coils of wound conductive patterns being formed on each conductive layer, and said coils of conductive layers being connected to each other via through holes formed on said insulating layers;
- and
- a rotor comprising a permanent magnet;
- wherein said stator is made of an inner stator and an outer stator which are respectively formed in a ring shape, and a rotor formed in a ring shape is provided between said stators which rotates integrally with a rotatably supported axis.
