Description
Technical field
The utility model relates to a kind of switched reluctance machines.
Background technique
Switched reluctance machines speed-adjusting driving system collection motor technology, power electronic technique, microelectric technique and automatic control
Innovation achievement and one, control simple, high-efficient with its structure is easy, efficient stepless speed regulation, at low cost equal unique excellent
Point has become other strong competitors of type motor speed-adjusting driving system in industrial circle, has wide application
Prospect.It is widely used in fields such as household electrical appliance, auto industry, traction electric machines, obtains huge economic benefit；And by
Step is applied to the occasions such as wind-power electricity generation, aviation starting power generation.However, switched reluctance machines have compared with other types motor
Biggish noise and torque pulsation, stator, the double-salient-pole structure of rotor and switching magnetic-resistance form power supply, so that switch
Reluctance motor driving system become a multivariable be highly coupled, the serious system of non-thread sexual abnormality, torque pulsation is non-in operation
Chang Mingxian, and easily cause noise of motor, switched reluctance machines are affected in the application of the more demanding occasion of running quality.Both at home and abroad
Scholar mainly reduces the torque pulsation of switched reluctance machines in terms of motor body structure optimization and control strategy two.However,
The research of Most scholars concentrates on control field, control strategy that many scholars are distributed based on torque, variable-structure control strategy
And modern control theory, propose new control strategy, but these methods based on control field increase the complexity of controller
And cost.Therefore, inhibit the research of switched reluctance machines to obtain more and more scholars based on ontology to pay attention to.
The minishing method of existing torque pulsation is largely all based on Optimal Control Strategy progress, and which increase be
The complexity and cost of system.And reduced in switched reluctance machines torque pulsation method based on research body construction, multi-pass crosses increase
Stator and rotor number of poles and the number of phases reduce torque to reduce torque pulsation or increase permanent magnet in Stators for Switched Reluctance Motors
The method of pulsation, equally, both methods also both increase the complexity and cost of system.
Summary of the invention
To solve the larger technical problem of present switched reluctance machines torque pulsation, the utility model provides a kind of switch
Reluctance motor.
In order to solve the above-mentioned technical problem, the technical solution of the utility model is：
It is convex to be equipped with multiple first in stator for a kind of switched reluctance machines, including stator, rotor and three-phase concentratred winding
Pole is externally provided with multiple second salient poles in rotor, is respectively equipped with one section of arc protrusion in each second salient pole two sides.
Stator and rotor are formed by silicon steel sheet laminated.
Arc protrusion is stationarily connected to one of the second salient pole side and the oval-shaped iron core of rotor magnetic pole equal length.
The utility model has the beneficial effects that：Compared with prior art, the utility model passes through in rotor with salient pole two sides point
Not She You one section of arc protrusion, the parallel teeth of traditional rotor is changed to drum type tooth, passes through optimization arc and protrudes semi-minor axis
Distance changes the Distribution of Magnetic Field of motor, optimizes motor gas-gap flux density so that motor torque ripple is significantly decreased and reaches suppression
The purpose of torque pulsation processed, advantageously reduces motor cost.
Detailed description of the invention
Following further describes the present invention with reference to the drawings：
Fig. 1 is the utility model schematic view of the front view,
Fig. 2 is the partial enlargement structural representation of the utility model,
Fig. 3 is the transient torque comparison diagram of the utility model when in use.
Specific embodiment
As shown in Fig. 1 to 3, a kind of switched reluctance machines, including stator 1, rotor 2 and three-phase concentratred winding 3, in stator 1
12 the first salient poles 11 are inside equipped with, being externally provided with 8 length in rotor 2 is the second salient pole of 16.8mm 21, at 21 liang of each second salient pole
Side is respectively equipped with one section of arc protrusion 22, and the semi-minor axis d length of arc protrusion 22 is 3.5mm.Utility model passes through convex in rotor 2
Pole two sides are respectively equipped with one section of arc protrusion 22, and the parallel teeth of traditional rotor 2 is changed to drum type tooth, convex by optimization arc
The distance of 22 semi-minor axis changes the Distribution of Magnetic Field of motor out, optimizes motor gas-gap flux density, so that motor torque ripple is shown
It writes and reduces, achieve the purpose that torque pulsation inhibited, advantageously reduce motor cost.
Stator 1 and rotor 2 are formed by silicon steel sheet laminated.This structure makes electric machine structure very simple and robust
Arc protrusion 22 is stationarily connected to one of 21 side of the second salient pole and the ellipse of 2 magnetic pole equal length of rotor
Iron core.
As shown in figure 3, establishing model after motor optimizes by Maxwell 2D transient analysis module, external circuit, structure are connected
Complete Control System Imitation model is built, finite element analysis is carried out to the torque for starting to steady-state process of motor.Motor speed
1500r/min, taking an emulation cycle time is 10ms, and motor uses Angle-domain imaging mode, each phase winding conducting
15 °, obtain the utility model and traditional structure switched reluctance machines transient torque comparison diagram.It can be seen from the figure that this is practical
Novel torque pulsation is substantially reduced.It is by the ripple torque coefficient that simulation calculation obtains the parallel tooth model of conventional motors rotor 2
98.66%, average torque 78.08Nm, the utility model ripple torque coefficient are 69.79%, average torque 66.22Nm.
By calculated result it is found that compared with conventional motors model, new construction motor torque ripple coefficient decline 29.26%, but average output
Torque decreases, and can be compensated by high current.
