摘要:
A brushless motor stator comprising a lamination body in which conductive layers 1 B and insulating layers 1A are formed alternately. A plurality of sets of coils 12 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.
摘要:
A two-phase motor having first and second coil arrays and magnet arrays. In the magnet array, N pole and S pole are arranged alternately while facing the first and second coil arrays. The first and second coil arrays are located while being shifted from each other by odd multiples of Π/2 of electric angle. Each coil in the first and second coil arrays substantially has no core of a magnetic body, and the motor substantially has no yoke of a magnetic body for forming a magnetic circuit.
摘要:
A two-phase electric motor in accordance with the present invention comprises first and second coil groups and a magnet group. In the magnet group, N poles and S poles are disposed alternatively opposite the first and second coil groups. The first and second coil groups are disposed at positions that are out of phase with each other by an odd multiple of π/2 in electrical angles. The coils of the first and second coil groups have substantially no magnetic material cores, and the electric motor has substantially no magnetic material yoke for forming a magnetic circuit.
