Embodiment
As shown in figs 1-9, described in the utility model without silicon steel sheet motor, comprise annular outer cover 1, with the stator 10, the rotor 12 that are located in this shell, with the pair of bearing 7 of rotating shaft 9 bearing fit of this rotor 12, each bearing pedestal 7 is fixed in described annular outer cover 1 by corresponding cover plate, and each coil layer on stator comprises 18,21,24 or 27 fan-shaped plan coils 15.
Permanent magnets 3 on rotor 12 is 2-20, symmetrical with circle center.
Described each coil layer adopts plastic hot to be pressed into one.
The outside of stator 10 is provided with magnetic conduction cover plate 2, and described magnetic conduction cover plate 2, stator 10, rotor 12 are located in non-magnetic annular outer cover 1.
The motor of the application is without the need to silicon steel sheet, and stator adopts lattice coil layer through plastics hot pressing ringwise, and thickness is generally and is less than 1cm.
Because stator in the motor of the application, rotor 12 are parallel adjacent and coaxially arrange, stator thickness is thin, therefore small volume, and the permanent magnets on the magnetic field that coil layer produces and rotor 12 forms closed magnetic path.
Due to the only just magnetic conduction when coil electricity, therefore magnetic leakage free and magnetic circuit impedance is little, permeability is high, so significantly can reduce coil turn, reduces the consumption of copper cash.
