Description
Technical field
The present invention relates to motor technology, and in particular to exports the coreless permanent magnet generator of square wave.
Background technology
Motor includes dc generator, alternating current generator, dc motor and ac motor, and they are all based on electromagnetism
The equipment that principle of induction mutually converts mechanical energy and electric energy, has coil windings, conventional electric generators stator coil winding has
When magnetic core, excitation or p-m rotor rotate, very big resistance is had between them, generating efficiency can be improved by reducing this resistance.
Utility model content
The purpose of this utility model is to cancel stator core, eliminates its resistance between excitation or p-m rotor and carry
High generation efficiency.
In order to solve the above problems, using following scheme：
The coreless permanent magnet generator of square wave is exported, it is N number of stator coil, N number of by rotating shaft, permanent magnet fixed disk, bearing
Stator coil frame, N are formed to permanent magnet, casing, cabinet cover, and stator coil is wound on bobbin, iron-core-free in bobbin, coil
Cross section size is identical with permanent magnet cross-sectional sizes, and bobbin is fixed in cabinet cover, the width of spacing and coil between coil
Spend it is identical, each pair permanent magnet to dress up for closed magnetic circuit structure be arranged on permanent magnet fixed disk on, N number of coil is in foregoing N
In the magnetic field of individual magnetic circuit, when the spindle is rotated, the rotation of closed magnetic circuit makes N number of coil cutting magnetic line and produces electric current.
Above-mentioned technical proposal is taken, is had the following effects that：
The utility model export square wave coreless permanent magnet generator, no stator core, eliminate stator coil winding with
Resistance between excitation or p-m rotor, improves generating efficiency.

Embodiment
As shown in Figures 1 to 5, at the middle part of a rotating shaft, a permanent magnet fixed disk is installed, in permanent magnet fixed disk
On, N is installed to permanent magnet to dressing up the structure for closed magnetic circuit, so forms a PM rotor, is wound with coil
Bobbin is arranged in the cabinet cover of both sides, and coil section is suitable with permanent magnetism body section, the width of spacing and coil between coil
It is identical, a cabinet cover, PM rotor, casing are sequentially fixed at another cabinet cover together with when, N number of coil is at
N on PM rotor is in the magnetic field of the structure magnetic circuit of closed magnetic circuit, when the spindle is rotated, the rotation of closed magnetic field makes N
Individual coil cutting magnetic line and produce electric current.
