Description
Technical field
The utility model relates to electric machine structure technical fields, more particularly, to a kind of motor rotor construction.
Background technique
Currently, being generally satisfactory with motor-driven new-energy automobile, motor is one of kernel component of vehicle,
The performance of motor decides the superiority and inferiority of vehicle.
Rotating electric machine is mainly that the power of the rotating excitation field of stator and rotor interaction generation is leaned on to do manual work.Common stator
Winding uses rectangular aperture slot frequently with form-wound coils, stator punching, and width of rebate is big, can generate stronger slot effect,
Biggish tooth-harmonic emf, cogging torque and torque ripple are accompanied by motor operation.In order to weaken slot effect, using turn
Sub tiltedly pole is optimal method.
Skewed-rotor is divided into two classes, and one kind is continuous oblique pole, another kind of, is step skewed pole.Most using continuous oblique pole effect
For ideal, but when built-in rotor is due to continuous oblique pole, permanent magnetism shape is special or embedded difficulty, and actual implementation is got up very tired
It is difficult.And step skewed pole is then more feasible, theoretically it is found that segments is more, the effect of oblique pole is better, divides however, increasing
Number of segment will necessarily increase the complexity of technique production, reduce the reliability of motor, more important is connect due to rotor segment
When it is rotary shifted be connected, there are problems that segmentation connection end axial direction leakage field, cause permanent magnet utilization rate poor, affect motor
Efficiency.
Utility model content
The purpose of this utility model is to provide a kind of motor rotor constructions, effectively improve the utilization rate of permanent magnet, reduce
Leakage field further increases the efficiency of motor.
In order to achieve the above object, the utility model uses following technical scheme：
A kind of motor rotor construction comprising rotor core, rotor core include at least two core packets, two neighboring iron
Non-magnetic plate is provided between core section, each core packet is formed by several rotor punching laminateds, opened up on each rotor punching
Have a magnet slot, the magnet slot of two neighboring core packet circumferentially overall offset set angle, non-magnetic plate and rotor punching it is outer
Shape size is identical, and the locking hole to walk for locking member is offered on non-magnetic plate, rotor punching, is also opened up on non-magnetic plate
There is air gap hole, the magnet slot of two neighboring core packet is connected to by air gap hole.
Wherein, set angle is less than 10 degree.
Wherein, non-magnetic plate is stainless steel plate.
Wherein, there are two locking hole is at least evenly distributed with.
Wherein, the number of air gap hole and magnet slot is correspondingly arranged.
To sum up, the beneficial effects of the utility model are, compared with prior art, the motor rotor construction is mainly to turning
Son uses step skewed pole structure, and non-magnetic plate is arranged between two neighboring core packet, so that effectively increasing permanent magnet
Utilization rate reduces leakage field, reduces winding loss, to improve the efficiency of motor, feasibility is high, and being suitble to gradually promote makes
With.
Detailed description of the invention
Fig. 1 is the structural schematic diagram of motor rotor construction provided by the embodiment of the utility model.
Specific embodiment
Further illustrate the technical solution of the utility model below with reference to the accompanying drawings and specific embodiments.
Refering to Figure 1, the present embodiment provides a kind of motor rotor constructions comprising rotor core, rotor core packet
At least two core packets are included, the present embodiment is illustrated with two adjacent core packets, the first core packet 1 and the second iron core
It is provided with non-magnetic plate 3 between section 2, non-magnetic plate 3 is set as stainless steel plate herein, is also possible to the materials such as resin.
Each core packet is formed by several 4 laminateds of rotor punching, offers magnet slot 5 on each rotor punching 4, and first
The circumferentially whole successively offset setting angle of magnet slot 5 of core packet 1, the second core packet 2, adjusts set angle as needed,
The angle that the magnet slot of the first core packet 1 is assumed in the present embodiment is 0 °, and the angle of the magnet slot of the second core packet 2 presses up time
Needle deviates 8 °, and 8 ° are successively deviated if there is also core packets such as third, the 4.
Particularly, it in order to guarantee that magnetism isolating effect and overall structure are beautiful, sets non-magnetic plate 3 to and rotor punching 4
Outer dimension is identical, is opened up on non-magnetic plate 3, rotor punching 4 there are two uniformly distributed locking hole 6, when installation, with locking member,
Such as rivet, screw, pin etc., each rotor punching 4 and non-magnetic plate 3 are passed through, realizes compacting-shaping and rotary stopper.It is illustrated as eight
The example of a magnet slot 5.
Be also provided with air gap hole 7 on non-magnetic plate 3, herein air gap hole 7 also be eight, air gap hole 7 by the first core packet 1,
The magnet slot 5 of second core packet 2 is connected to.It should be noted that the deviation angle due to two core packets herein is smaller, the two
There are overlapping regions on projecting to non-magnetic plate 3 for magnet slot 5, thus 7, air gap hole need open up as small ventilating holes.If going out
Existing non-overlapping region can then open up as strip-shaped hole, but hole shape all should not be too large, in order to avoid influence magnetism isolating effect.
To sum up, motor rotor construction provided in this embodiment mainly uses step skewed pole structure to rotor, and adjacent
Non-magnetic plate is set between two core packets, so that effectively increasing the utilization rate of permanent magnet, reduces leakage field, reduces winding
Loss, to improve the efficiency of motor, feasibility is high, is suitble to gradually promote the use of.
Above embodiments only elaborate the basic principles and features of the present invention, and the utility model is not by above-mentioned example
Limitation, on the premise of not departing from the spirit and scope of the utility model, the present invention has various changes and changes, these changes
Change and change is fallen within the scope of the claimed invention.The utility model requires protection scope is wanted by appended right
Ask book and its equivalent thereof.
