Description
Technical field
This utility model belongs to reluctance motor technical field, more particularly to a kind of T-shaped 4/2 structure switch magnetic resistance motor.
Background technology
Nowadays, as high-speed electric expreess locomotive has the features such as size is little, and power density is big, high-speed electric expreess locomotive is more and more employed
In industry and domestic electrical equipment.Switched reluctance machines are a kind of double-salient-poles, and the motor of single excitation structure, simple structure hold
Wrong performance is good, can run in high temperature, under conditions of at a high speed.Under a specific speed, motor open shut-off frequency with
The number of poles of the number of phases and rotor of motor is directly proportional.The number of phases and rotor number of poles of motor is fewer, motor open shut-off frequency it is less,
Loss is less, so monophase machine and two-phase induction motor are widely used in High Speed System.
The switched reluctance machines of biphase 4/2 structure of tradition, its torque pulsation are big, and noise is big, and has " dead band " --- torque
It is zero region, causes which to be unable to self-starting.Therefore, in the design process of electric machine structure, how to reduce torque pulsation and disappear
Except the region that torque is zero so as to energy self-starting, become the larger obstacle of biphase switched reluctance machines design.
Utility model content
To solve the above problems, the utility model proposes a kind of T-shaped 4/2 structure switch magnetic resistance motor, its simple structure, set
Meter rationally, be easily installed and implement.
The technical scheme adopted by this utility model is：A kind of T-shaped 4/2 structure switch magnetic resistance motor, including rotor, rotor
Yoke and motor shaft, are characterized in that：Rotor is T-type structure, and rotor includes T-shaped rotor top and T-shaped rotor bottom, T-shaped turn
Sub- top is each attached on rotor yoke with T-shaped rotor bottom, and motor shaft is moved by rotor yoke rotor driven, T-shaped rotor bottom
Radian be T-shaped rotor top radian twice, T-type structure rotor bottom a length of T-shaped rotor top unshakable in one's determination is unshakable in one's determination long three points
Two.
Described T-shaped rotor top is isometric with rotor yoke.
Described T-shaped rotor bottom is located in the middle of rotor yoke.
Advantage of the present utility model and beneficial effect are：The motor is T-shaped 4/2 structure switch magnetic resistance motor, compared to biography
Unite 4/2 structural electromotor, the rotor core length of T-shaped rotor structure motor is inconsistent, makes motor inductances asymmetric, and air gap flux density is more
Uniformly, and its positive torque is interval is more than 90 °, zero torque zone is eliminated, is not had in " dead band ", motor energy self-starting.Identical
When input condition under, while the average output torque of model machine is improved, reduce torque pulsation and noise, improve efficiency, institute
Rotor core quality is less, and iron-core mass reduces 10%, improves the utilization rate of iron core.
