The salient pole of its normal stator and rotor is overrided to form by oOrdinary silicon steel sheet.Rotor is wound with collection both without winding or without permanent magnet in stator poles
Middle winding, two windings diametrically link up, and are referred to as " phase ", and switched reluctance machines can be designed to a variety of different phases
Table structure, and the number of poles of stator and rotor has a variety of different collocation, cash is widely used in electric car driving, universal industrial, family expenses
The every field such as electrical equipment and textile machine.
Switched reluctance machines have the systematic function of brilliance, but the centralized winding of switched reluctance machines has heating to concentrate, dissipate
The characteristics of heat is bad, this requires the winding of motor to be preferably provided with other medium auxiliary heat dissipation conditions, such as cross-ventilation etc..It is existing
It is slab construction to have switch reluctance machine rotor both ends end plate, does not promote the effect of air circulation, have impact on the entirety of motor
Heat dispersion.To ensure to radiate, existing technology generally increases special radiator fan, such as Chinese patent document at motor both ends
(application number 201610775346.8) provides a kind of pure electric ship Special switch magneto-resistance motor, including casing, shell, pile body
And charging pile, casing pass on left stator and are rotatablely connected with rotor, be connected above casing by terminal box with binding post, casing
Right side is connected by end cap with magnetic conductive disk, and fan is provided with the right side of magnetic conductive disk.This not only needs specially to buy a fan, increase
The cost of motor, it is also necessary to exclusively for fan design installing space, add the design cycle, the volume and length of motor also increase
Add.In addition, fan also requires on installation is fixed, also can band if improper use can cause the improper operating of motor
To vibrate and a series of problems, such as noise.
Utility model content
In view of the shortcomings of the prior art, the utility model provides a kind of switch reluctance machine rotor with fan leaf.
The technical solution of the utility model is as follows：
