Description
Technical field
The utility model relates to motor fields, and in particular to a kind of low torque ripple synchronous magnetic resistance motor.
Background technique
Synchronous magnetic resistance motor is a kind of motor D axis different from Q axle inductance generation reluctance torque driving rotor to be utilized to drive
The motor of shaft rotation.Since it is simple with structure, handling ease, rotor surface is smooth, and loss is small, and fault-tolerant operation ability is strong
The features such as, therefore it is widely used in industrial drives field.For synchronous magnetic resistance motor, reluctance torque direct ratio and D axis and Q axis
Inductance difference.In order to increase synchronous reluctance motor torque output, it is necessary to expand the inductance difference of D axis Yu Q axis, improve electricity
The saliency of machine.Therefore it must slot on the rotor of motor.Due to the presence of fluting and saliency on rotor,
Keep the torque pulsation of synchronous magnetic resistance motor larger.And torque pulsation can cause the vibration and noise of motor, influence the performance of motor,
Therefore urgently to be resolved.
Summary of the invention
The utility model is directed to the deficiency of current synchronous magnetic resistance motor, and the utility model provides a kind of reduction synchronous reluctance
The motor of motor torque ripple.
In order to solve the above technical problems, a kind of low torque ripple synchronous magnetic resistance motor of the utility model, including stator and
Rotor, the stator include stator slot, and affiliated rotor includes rotor slot, it is characterised in that: circumferentially shape is uniform for the stator slot
Distribution, the quantity that every a pair of pole is equipped with stator slot is ns；
The end of the rotor slot is uniformly distributed along rotor edge, and the outer edge of the rotor is segmented by the rotor slot
Several segmentations A, the quantity of the segmentation A is nr；
The quantitative relation of the quantity of the stator slot and the segmentation A are as follows: ns=nr+ 4, and/or, ns=nr-4。
A kind of low torque ripple synchronous magnetic resistance motor of the utility model passes through the Coupling Design of stator and rotor, reduces same
The torque pulsation for walking reluctance motor, further decreases the noise and vibration of synchronous magnetic resistance motor.

Specific embodiment
Below by embodiment 1, and in conjunction with attached drawing, the utility model is described in further detail:
Embodiment 1
As shown in Figure 1, a kind of low torque ripple synchronous magnetic resistance motor of the utility model, the stator slot 6 in stator 5 is along circle
Week is uniformly distributed, and each pair of quantity for extremely descending stator slot 6 is parameter ns.Several rotor slots 2, rotor slot 2 have been distributed in rotor 1
End be uniformly distributed along rotor edge, and by the outer edge disjunction of rotor 1 at several segmentations, the quantity of segmentation is parameter
nr.This disjunction is virtual.When the quantity of each pair of quantity for extremely descending stator slot 6 and rotor segment 4 meets following formula relationship, at this time
The torque pulsation of motor is smaller.
ns=nr±4
As in Figure 2-4, in three rotor schemes, the slot number of stator 5 is 36, and each pair of quantity for extremely descending stator slot 6 is 18.
4 quantity of segmentation of rotor 1 shown in Fig. 2 is 14, and 4 quantity of segmentation of rotor 1 shown in Fig. 3 is 18, rotor 1 shown in Fig. 4
The quantity of segmentation 4 is 22.Corresponding torque pulsation result is as shown in Fig. 5,6,7 under their identical loads.In contrast, Fig. 2 and
The torque pulsation of torque pulsation ratio Fig. 3 scheme of the scheme of Fig. 4 is obviously small, and wherein the torque pulsation of the scheme of Fig. 4 is minimum.
The utility model passes through the Coupling Design of stator and rotor, reduces the torque pulsation of synchronous magnetic resistance motor, further
Reduce the noise and vibration of synchronous magnetic resistance motor.
Finally it should be noted that listed above is only specific embodiment of the utility model.Obviously, this is practical new
Type is not limited to above embodiments, can also there is many variations.Those skilled in the art can be from disclosed by the utility model
All deformations for directly exporting or associating in content, are considered as the protection scope of the utility model.
