Embodiment
The present invention is further described below in conjunction with the accompanying drawings.As shown in Figure 1-2, a kind of integrated form permanent magnetism compound electric
Machine, including field frame assembly and rotor assembly.
Described field frame assembly includes stator core 1 and stator winding 2；The silicon that described stator core 1 is insulated by two sides
Steel disc is overrided to form, and shape identical composite slot is uniformly distributed circumferentially in stator core 1；Described composite slot is by one
" rectangular channel " and multiple " type grooves " is formed；Described rectangular channel one side communicates with multiple type grooves, another side and field frame assembly and turns
Air gap between sub- assembly communicates；The number of described rectangular channel is equal to the described number of pole-pairs of stator winding 2 and p-m rotor
Number of pole-pairs sum；Described stator winding 2 is wound in the type groove of stator core 1.
Described rotor assembly includes power output shaft 5, permanent magnet 4 and rotor core 3.
The silicon steel sheet or permeability magnetic material that described rotor core 3 is insulated by two sides are made；It is provided with the axle center of rotor core 3
Centre bore；The permanent magnet type groove being uniformly distributed circumferentially is provided with close to 3 cylindrical place of rotor core, for laying simultaneously fixed permanent magnet
4；The centre bore of rotor core 3 is sleeved on power output shaft 5 by key connecting or interference fit.
Further, described permanent magnet 4 is shoe or rectangle, at the permanent-magnet type slotted eye of rotor core 3.
Further, described power output shaft 5 passes through key connecting mode or interference fit connecting mode and rotor core 3
It is connected.
Further, described composite slot is made up of a rectangular channel and 3-9 " type groove ", the center line and stator of type groove
1 RADIAL unshakable in one's determination is conllinear.
The operation principle of the present invention is as follows：
The present invention, which becomes one concentric type permanent magnet gear and magneto, forms permanent magnetism compound machine, including stator is total
Into and rotor assembly, one layer of even air gap wherein between field frame assembly and rotor assembly be present.
The stator winding 2 of the present invention produces rotating excitation field when being passed through alternating current, and forms magnetic pole logarithm；Due to stator iron
The composite slot of the heart 1 is " rectangular channel+several type grooves ", and rectangular channel therein not magnetic conduction, it is act as every magnetic, and with rectangular channel phase
Adjacent is then the very big stator core 1 of magnetic conductivity, thus rectangular channel and adjacent stator core 1 serve to stator winding 2 and
Permanent magnet 4 carries out magnetic conduction or the effect of non-magnetic adjustable magnetic, and its effect is identical with the adjustable magnetic ring in existing concentric type permanent magnet gear,
Can by air-gap field caused by stator winding in the present invention 2 and rotor assembly as caused by permanent magnet 4 air-gap field phase
Mutually match and couple：Rotating excitation field i.e. caused by stator winding 2, the harmonic field formed after adjustable magnetic acts on can be total with rotor
The fundamental wave magnetic field formed into middle permanent magnet 4 matches, and forms certain gearratio.
The present invention have less magnetic pole logarithm for high speed rotor, conversely, being then low speed rotor；That is permanent magnetism in rotor assembly
If the magnetic pole logarithm that the magnetic pole logarithm that body 4 is formed is formed when being powered less than stator winding 2, described permanent magnetism compound machine is increasing
Speed motor；Conversely, it is then reducing motor.
The present invention is not limited to the present embodiment, any equivalent concepts in the technical scope of present disclosure or changes
