Abstract
The invention discloses a switch magnetic resistance motor rotor structure. Two sides of a rotor tooth are provided with axial direction through connection holes which are embedded with a connection conductor. Two ends of the connection conductor connect with copper rings at two ends of a motor. Through communication of the copper rings and copper bars, a damping winding is formed.

Description
Technical field
The present invention relates to technical field of motors, particularly a kind of switch reluctance machine rotor structure.
Background technology
Switched reluctance machines is a biconvex utmost point VR motor, and the salient pole of its stator and rotor is overrided to form after by common punching silicon-steel, and the stator and rotor number of poles is different, and the simple winding of concentrating is housed on the stator, and rotor only is made up of lamination, does not have winding and permanent magnet.Reluctance motor forms torque unlike the such magnetic field interaction that relies on the stator and rotor winding current to produce of conventional motors; But follow the magnetic resistance minimum principle; Be that magnetic flux is always closed along the minimum path of magnetic resistance, so magnetic field distortion and produce the tangential magnetic pull and form the electromagnetic torque of magnetic resistance character.
Because switched reluctance machines has simple in structure, advantages such as cost is low, efficient is high, good speed adjustment features and is widely used in electric motor car, household electrical appliance and elaborate servo system etc.; But also there are some shortcomings; Since its control mode and operation logic determined motor in operation and starting as if wanting to seek higher moment; Just must strengthen distance between tooth top and the tooth root as much as possible; Flux change is unexpected all the more like this, has caused the pulsation of motor rotating torque big, and the vibration of motor itself and electromagnetic noise are bigger than general motor.
Summary of the invention
The objective of the invention is provides a kind of technology comparatively simple in order to overcome the deficiency of prior art, can effectively reduce the switch reluctance machine rotor structure of torque pulsation and electromagnetic noise vibration.
The technical problem that the present invention solves takes following technical scheme to realize:
A kind of switch reluctance machine rotor structure; Comprise axle 1, rotor tooth portion 2, rotor yoke 3, screw hole 4; It is characterized in that: also comprise connecting hole 5, bonding conductor 6 and copper ring 7; Each rotor tooth portion 2 both sides have the connecting hole 5 of axial perforation, and bonding conductor 6 passes connecting hole 5, and the two ends of bonding conductor 6 link to each other with the copper ring 7 at rotor core two ends respectively.
Said bonding conductor 6 can be copper rod or enamelled wire.
The thickness of said copper ring 7 is preferably 2 times of bonding conductor 6 diameters.
Adopted the embedded bonding conductor of rotor tooth portion, through copper ring each bonding conductor has been communicated with the structure that constitutes damping winding again, guaranteed that the height of rotor tooth portion is constant, the starting torque of motor can not reduce like this.To the motor stator winding energising, produce magnetic field between stator poles, work as magnetic flux during rotor operation through between two teeth; Because changes of magnetic field bonding conductor two ends produce induced electromotive force, constitute loop near two bonding conductors of a side with copper ring in adjacent teeth portion, produces the magnetic field that an obstruction magnetic flux suddenlys change; So just make that the inductance intensity of variation weakens on the main flux; Torque fluctuation reduces, and has reduced harmonic loss, has reduced electromagnetic noise.
The present invention compared with prior art has significant advantage and beneficial effect, is embodied in the following aspects:
The switched reluctance machines of use rotor core structure of the present invention not only efficient is high, and in the very wide power and the range of speeds, can both keep high efficiency, and this is that other type drive system is unapproachable.This specific character is particularly suitable to the ruuning situation of electric motor car, helps improving the continual mileage of electric motor car, and greatly strengthens the comfort level of driving, and is highly suitable for the use of pure electric sedan.
Use rotor core switched reluctance machines of the present invention to be easy to through adopting suitable control strategy and system design to satisfy the requirement of electric motor car four quadrant running, and can also keep strong stopping power in the high-speed cruising zone.
Use rotor core of the present invention to adopt switched reluctance machines will bring many benefits as the main transmission of shuttleless loom in the textile industry; Reduce travelling gear, without belt and belt pulley; Without electromagnetic clutch and brake disc, need not seek the latitude motor, advantage such as energy-conservation 10%; Reduce the work mistake that brings owing to torque pulsation, and increase the service life.
