Formula structure and have both radial, three kinds of hybrid combination of tangential feature.Internal permanent magnet synchronous motor rotor structure is not
It is same to generate Different Effects to the performance of motor.In radial structure, every pole magnetic flux is provided in series by two permanent magnets, radial
Formula rotor structure is relatively simple, and operational reliability is high, is widely used；In tangential structure, every pole magnetic flux is by adjacent two
Permanent magnet parallel connection provides, and can obtain bigger air gap flux density, the higher occasion for being suitble to certain specific flux densities to require；Hybrid knot
In the rotor of structure, by being provided in series after two permanent magnets parallel connections with another two permanent magnet, this structure turns every pole air-gap flux
Son number of pole-pairs compared with radial or tangential halves, and can obtain the air gap flux density higher than radial, but structure is complex
It is higher for the requirement on machining accuracy of groove profile and permanent magnet.In the prior art, according to the difference of application, people need to select
The internal permanent magnet synchronous motor different with design structure.When application or user's changes in demand, need again more
Magneto is changed or designed to meet the needs of different.It needs to need use to cut using the radial motor later period in certain early periods
Into the application of formula motor, then needs to design two sets of permanent magnet machine rotors, greatly causes design cost and the wasting of resources,
It is unfavorable for the versatility of motor.
Summary of the invention
The purpose of the present invention is to provide the rotors that a kind of one is mostly used permanent magnet synchronous motor, to realize by changing rotor
Middle permanent magnet arrangement changes rotor structure and motor number of pole-pairs, realizes that a kind of rotor forms a variety of motor forms.
The technical solution for realizing the aim of the invention is as follows:
A kind of multi-purpose permanent-magnetic synchronous motor rotor of one, the rotor includes rotor core, through iron core and along iron core week
To the multiple shafts being evenly arranged；In the permanent magnet insertion shaft；The shaft is axially parallel to iron core axial direction；The permanent magnetism
Body can be rotated along rotating shaft core.
Compared with prior art, the present invention its remarkable advantage:
(1) present invention changes permanent magnet cartridge insertion direction in rotor, in motor by the way that rotatable permanent magnet slot is arranged
In the case that rotor structure is constant, it may be implemented mutual between radial permanent magnet synchronous motor and tangential permanent magnetic synchronous motor
Conversion, improves the versatility of permanent magnet synchronous motor.
(2) present invention changes permanent magnet cartridge insertion direction in rotor, in motor by the way that rotatable permanent magnet slot is arranged
In the case that rotor structure is constant, halving and doubling for permanent magnet synchronous motor number of pole-pairs may be implemented, improve permanent magnet synchronous motor
Versatility.
(3) a kind of permanent-magnetic synchronous motor rotor structure may be implemented in the present invention, and collocation forms a variety of motor forms, meets more
Kind occasion demand, avoids the limitation that a permanent magnet machine rotor only adapts to a kind of workplace.
Present invention is further described in detail with reference to the accompanying drawing.
