The magnetic pole length H of son 22 is longer than the folded thickness L of stator core 11；Wherein, the magnetic pole length H of the rotor 22 is rotor magnetizer
221 length.
Compared with prior art, the poly- magnetic-synchro motor of efficient ferrite provided by the invention, stator module include stator iron
Core and the embedding armature winding being around in stator core slot, rotor assembly use cutting orientation magnetizing structure, and rotor assembly includes main shaft, turns
Son, front apron and rear baffle, rotor include that rotor magnetizer, tangential magnetized ferrite magnet steel and attachment base, the magnetic pole of rotor are long
Degree is longer than the folded thickness of stator core, and the tangential magnetized ferrite magnet steel for being thus longer than stacked stator core thickness can be by being longer than stator

It is greater than 3.5mm in 4mm, the depth of rebate D of the dovetail groove of the attachment base 223, the attachment base 223 uses magnesium-aluminium alloy material
The intensity for ensuring that attachment base 223 is made, should also use up can by the thickness A of tangential magnetized ferrite magnet steel 222 and length B at this time
It can do bigger, since the attachment base 223 is made of non-magnet material magnesium alloy, and rotor magnetizer 221 uses steel plate
Punching press is formed by stacking, therefore the rotor magnetizer 221 being located in dovetail groove will not be to 223 leakage field of attachment base, thus this connection
The rotor structure leakage field that seat 223 and rotor magnetizer 221 are separately formed is minimum, and the magnetic pole length H and stator core of rotor
The ratio between folded thickness L be also it is lesser, it is the 1.7 of stacked stator core thickness that take H:L at this time, which be the magnetic pole length of the 1.7 i.e. described rotors,
Times, so that it may so that air gap flux density is greater than 1.0 teslas, meet the requirement of air gap flux density.
It as specific embodiment, please refers to shown in Fig. 5, the attachment base 223 and rotor magnetizer 221 use steel plate punched
It is integrally molded so as tinertoy punching 7, and overlapping is carried out to tinertoy punching 7 and riveting composition is carried out by the punching in tinertoy punching 7
Whole pole wheel structure, due to 221 one of the attachment base 223 and rotor magnetizer in this whole pole wheel structure
Molding, therefore structure is relatively easy, is easy to make；But due to the attachment base 223 and rotor magnetizer 221 be one at
Type, the rotor magnetizer 221 in dovetail groove are easy to 223 leakage field of attachment base, thus this whole pole wheel fabric drain
Magnetic is larger, to reach the air gap flux density requirement of 1.0 teslas, and the ratio between magnetic pole length H and the folded thickness L of stator core of rotor will add
Greatly, take at this time H:L be 2.0~2.5 i.e. described rotors magnetic pole length be stacked stator core thickness 2.0~2.5 times, so that it may reach
To the air gap flux density requirement of 1.0 teslas, but more rotor material is needed at this time.
Finally, it is stated that the above examples are only used to illustrate the technical scheme of the present invention and are not limiting, although referring to compared with
Good embodiment describes the invention in detail, those skilled in the art should understand that, it can be to skill of the invention
Art scheme is modified or replaced equivalently, and without departing from the objective and range of technical solution of the present invention, should all be covered at this
In the scope of the claims of invention.
