Abstract
The utility model provides a wrong utmost point permanent magnet rotor, its characterized in that includes that two sections centres are two sections rotor core sections that are used for the centre bore of cross -under axle, a plurality of permanent magnets of setting in every section rotor core section, are a plurality of permanent magnets according to N the S utmost point distributes alternately in the rotor core section, two sections rotor core section cross -sections are identical, be provided with the navigation key in the rotor core section centre bore, navigation key and the permanent magnet N utmost point or a S utmost point pole center skew angle A, when two sections rotor core section combinations, cross -section second section rotor core section along Z axle upset 180 degrees the same with first section rotor core section completely, put rotatory alignment navigation key along central point again, the rotor core that constitutes realizes the two rotor core section magnetic poles angle 2A that staggers. Compared with the prior art, the utility model, having and easily realizing the wrong utmost point of rotor, messenger manufacturing process is simple, and simple to operate is with low costs, is applicable to middle -size and small -size PMSM's advantage.
Description
This utility model is related to that the rotor core of rotor mistake pole, the technical field of category permagnetic synchronous motor can be realized.
Background technology
Present permagnetic synchronous motor, in order to reduce harmonic wave, reduce cogging torque, typically all using skewed stator slot or rotor
Wrong pole, for skewed stator slot after, rule can be caused difficult, and automatic coil inserting apparatus, low production efficiency can not be adopted.And for turn
Sub- mistake pole, current mode is：Axial rotor iron core is divided into into multistage, multiple location holes have been positioned apart from iron core, it is multiple
The center of circle of location hole is on same circumference, and the circumference is concentric with the rotor core；During assembling, adjacent rotor list
Unit is staggered setting by arranging multiple location holes on rotor core so that two adjacent rotor units are in the axial direction of p-m rotor
Stagger on direction, finally tightened together using bolt, adopt the structure wrong pole rotor core be generally used for it is large-scale forever
, pair with minitype permanent magnetism synchronous motor due to being fastened using bolt, there is bolt head and be difficult to keep away in magnetic-synchro motor because space limits
Empty problem, manufacturability is poor.
Utility model content
The technical problems to be solved in the utility model 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, low cost, it is adaptable to middle-size and small-size permagnetic synchronous motor.
This utility model purpose is realized in：It is the two-stage rotor for wearing the centre bore of spindle including two sections of centres
Core packet, some permanent magnets being arranged in every section of rotor core section, some permanent magnets are alternately distributed in rotor according to N-S poles
On core packet, two-stage rotor core packet section is identical, is provided with positioning key in rotor core section centre bore, positioning key with forever
Magnet N poles or S poles pole center offset an angle A, when two-stage rotor core packet is combined, section completely with first paragraph rotor ferrum
Core section identical second segment rotor core section overturns 180 degree along Z axis, then along center rotation into alignment positioning key, is constituted
Rotor 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, and only a section in two iron leg cores need to be carried out into upset achieves that wrong pole, production efficiency
It is high.

Specific embodiment
This utility model is further described with reference to the accompanying drawings and examples
As shown in Figure 1, 2, 3, this utility model purpose is realized in：Including two sections of centres for wearing spindle in
The two-stage rotor core packet 1a in heart hole 5, be arranged in every section of rotor core section 1a for wearing some permanent magnets for connecing permanent magnet 2
Groove 3, rotor core section 1a is formed by stacking by some punchings, and some permanent magnets 2 are alternately distributed in rotor core section according to N-S poles
On 1a, two-stage rotor core packet 1a sections are identical, positioning key 4 are provided with rotor core section 1a centre bore 5, such as Fig. 1 institutes
Show, N pole or S pole pole center skew one angle A of the positioning key 4 with permanent magnet 2, when two-stage rotor core packet 1a is combined, such as
Fig. 4, shown in 5, section completely with first paragraph rotor core section 1a identical second segment rotor core section 1a（As shown in Figure 5）Along Z
Axle overturns 180 degree, then along center rotation into alignment positioning key 4（As shown in Figure 1,3）, the rotor core 1 for being constituted realizes two
Rotor core section 1a magnetic pole offset angular 2A, positioning key 4 is inlayed into the keyway on axle and fixes two rotor core sections 1a.
