Description
Technical field
The utility model belongs to technical field of motors, is related to a kind of rotor, more particularly to a kind of Permanent Magnet and Electric of step skewed pole
Machine rotor.
Background technology
Permagnetic synchronous motor is the synchronous motor that synchronous rotary magnetic field is produced by permanent magnet excitation.In recent years, with electric power
Electronic technology, microelectric technique, the fast development of New-type electric machine control theory and rare earth permanent-magnetic material, permagnetic synchronous motor are able to
Rapid popularization and application.Compared with traditional excitation magnetic synchronization motor, permagnetic synchronous motor have loss less, efficiency high, economize on electricity effect
Fruit clear advantage.Permagnetic synchronous motor provides excitation with permanent magnet, makes electric machine structure relatively simple, reduces processing and assembles
Expense, and the collector ring and brush easily gone wrong is eliminated, improve the reliability of motor operation；Again because without excitation electricity
Stream, without excitation loss, improves the efficiency and power density of motor, thus it is to study more and in every field in recent years
A kind of more and more extensive motor of middle application.The today for being increasingly subject to pay attention in the saving energy and environmental protection, it is studied just
Seem very necessary.
Wherein the oblique pole of rotor segment is that one kind can effectively weaken slot ripples, improve motor cogging torque and torque arteries and veins in motor
Dynamic method.A kind of step skewed pole formula permanent-magnetic synchronous motor rotor that such as Application No. 201210148034.6 is announced, leads to
It is in iron to cross the 54th iron leg heart bolt hole center of circle and the line in the axis hole center of circle and the pole center line of permanent magnet in the patent specification
Heart screw angle, the screw angle unshakable in one's determination of each rotor unit is axially incremented by successively along rotating shaft, and can with reference to patent Fig. 7, Fig. 8
Know, because the screwhole position of each of which core part is different, it is therefore desirable to which opening up many secondary moulds could realize that production cost is higher.
It is general tiltedly extremely many using keyway positioning, Er Qiefen in the case where only opening a secondary mould in order to reduce production cost
Segment number is limited, and can only be divided to two sections.
The content of the invention
The purpose of this utility model can be effectively reduced there is provided one kind for the above-mentioned problems in the prior art
Production cost, and the more permanent magnet machine rotors of number of fragments.
The purpose of this utility model can be realized by following technical proposal：A kind of permanent magnet machine rotor of step skewed pole,
Stainless steel cover plate is provided with several iron cores including sequentially coaxially spread configuration, the both ends of the surface of the iron core, if described
Dry passes through tightening of rivet between iron core and two cover plates, it is characterised in that along the circumferential direction uniformly arranged on described iron core
Offer on some magnet steel grooves, described iron core and uniformly to offer some groups of positioning holes positioned at each magnet steel groove edge, it is described
Each iron core between by positioning hole successively rotational offset arrangement step skewed pole is formed by tightening of rivet again.
The technique effect of the permanent magnet machine rotor of this step skewed pole is：In order to reduce production cost, a secondary mould is only being opened
In the case of each rotor core structure all same, by uniformly opening up some groups of positioning holes, each iron core on iron core
Between make skewed-rotor by the way that positioning hole is staggered successively, wherein pore size can according to after iron core size and intensive analysis really
It is fixed.Such as every section angle [alpha] that staggers, is divided into n sections, opens 360/ [α * (n-1)] individual hole on suitable circumferential spread on iron core,
Number of rivets n1 as needed, is divided into n1 deciles by hole, and n adjacent holes are included per decile.
In a kind of permanent magnet machine rotor of above-mentioned step skewed pole, the slot number phase of the group number and magnet steel groove of the positioning hole
Together.
In a kind of permanent magnet machine rotor of above-mentioned step skewed pole, in every group of described positioning hole the number of positioning hole with
The segments of iron core is identical.
In a kind of permanent magnet machine rotor of above-mentioned step skewed pole, the slot number of the group number and magnet steel groove of the positioning hole is equal
For 8.
In a kind of permanent magnet machine rotor of above-mentioned step skewed pole, the number and iron of positioning hole in every group of positioning hole
The segments of core is 4.
Compared with prior art, the permanent magnet machine rotor of this step skewed pole has reduction production cost simple in construction and divided
The more oblique more preferable advantages of pole effect of hop count.
