Abstract
A staggered pole permanent magnet rotor is disclosed and is characterized by comprising two rotor iron core segments and a number of permanent magnets arranged on both the rotor iron core segments, wherein middle parts of the rotor iron core segments are central holes through which a shafts can run and be connected, the permanent magnets are distributed on the rotor iron core segments in such a way that N and S poles are alternately arranged, the two rotor iron core segments have the same cross section, positioning keys are arranged in the rotor iron core segments, and the positioning keys deviate from a center of an N or S pole of a permanent magnet by an angle A; when the two rotor iron core segments are combined, a second rotor iron core segment which has the same cross section as the first rotor iron core segment is turned 180 degrees along a shaft Z, then the second rotor iron core segment rotates along a central position till the positioning keys are aligned, and magnetic poles of the two second rotor iron core segments in a rotor iron core formed thereby are staggered at an angle of 2A. Compared with technologies of the prior art, the staggered pole permanent magnet rotor is advantaged by easy rotor pole staggering operation, simple manufacturing technologies, convenience of installation, low cost, and suitability for small and medium-sized permanent-magnet synchronous electric motors.
Description
The present invention relates to the rotor core of rotor mistake pole can be realized, belong to the technical field of permagnetic synchronous motor..
Background technology
Present permagnetic synchronous motor, in order to reduce harmonic wave, reduce cogging torque, typically all adopts skewed stator slot or rotor
Wrong pole, after skewed stator slot, can cause rule difficult, and can not adopt automatic coil inserting apparatus, low production efficiency.And for turn
Son mistake pole, current mode is: axial rotor iron core is divided into multistage, iron core has been positioned apart from multiple location holes, multiple
The center of circle of location hole is on same circumference, and described circumference is concentric with described rotor core；During assembling, adjacent rotor list
Unit by arrange on rotor core multiple location holes stagger setting so that adjacent two rotor units p-m rotor axial direction
Stagger on direction, finally tightened together using bolt, adopt the structure wrong pole rotor core be generally used for large-scale forever
Magnetic-synchro motor, is difficult to keep away because space restriction has bolt head due to fastening using bolt to minitype permanent magnetism synchronous motor
Empty problem, manufacturability is poor.
Content of the invention
The technical problem to be solved in the present invention is to provide a kind of new wrong pole p-m rotor, can easily realize rotor wrong
Pole, makes manufacturing process simple, easy for installation, and low cost is it is adaptable to middle-size and small-size permagnetic synchronous motor.
The object of the invention is realized in: two sections of centres of inclusion are the two-stage rotor iron cores of the centre bore for wearing spindle
Section, some permanent magnets being arranged in every section of rotor core section, some permanent magnets are alternately distributed in rotor core according to n-s pole
Duan Shang, two-stage rotor core packet section is identical, and rotor core section center in the hole is provided with positioning key, positioning key and permanent magnet
N pole or s pole pole center offset angle a, and when two-stage rotor core packet combine, section is complete and first paragraph rotor core section
Identical second segment rotor core section overturns 180 degree along z-axis, then along center rotation into alignment positioning key, the rotor being constituted
Iron core realizes two rotor core section magnetic pole offset angular 2a.
Beneficial effect
1. punching carries positioning key, easy to assembly, simple production process；
2. iron core adopts stagewise, only a section in two iron leg cores need to be carried out upset and achieve that wrong pole, production efficiency is high.

Specific embodiment
The invention will be further described with reference to the accompanying drawings and examples
As shown in Figure 1, 2, 3, the object of the invention is realized in: two sections of centres of inclusion are the centre bores 5 for wearing spindle
Two-stage rotor core packet 1a, be arranged in every section of rotor core section 1a for wearing some permanent magnet trough 3 connecing permanent magnet 2, turn
Sub- core packet 1a is formed by stacking by some punchings, and some permanent magnets 2 are alternately distributed in rotor core section 1a according to n-s pole,
Two-stage rotor core packet 1a section is identical, is provided with positioning key 4 in rotor core section 1a centre bore 5, as shown in figure 1, fixed
Position key 4 offsets angle a with the n pole of permanent magnet 2 or s pole pole center, when two-stage rotor core packet 1a combine, as Fig. 4,5
Shown, section is completely and first paragraph rotor core section 1a identical second segment rotor core section 1a(is as shown in Figure 5) along z-axis upset
180 degree, then along center rotation into alignment positioning key 4(as shown in Figure 1,3), the rotor core 1 being constituted realizes two rotor ferrum
Core section 1a magnetic pole offset angular 2a, positioning key 4 is inlayed and is fixed two rotor core sections 1a in the keyway on axle.
