Abstract
This invention relates to a post salient pole compound rotary structure of a salient pole rotor motor characterizing in utilizing several ring plates of non-magnetic conductive material in same outer diameter to plug in the core of the salient pole rotor lamination in gaps to show a post profile with a narrow cavity to be installed and fixed on a shaft with a clamp located by a location slot or a hole in the ring plate of the salient pole rotor core lamination and the non-magnetic conductive material. Advantage: the post salient pole compound rotor can reduce the wind resistance of the rotor and is good to heat radiation and vibration reduction.
Description
Technical field
What the present invention relates to is the column-projection-polar composite rotor structure of salient poles rotor motors, belongs to technical field of motors.
Background technology
The rotor of motors such as switched reluctance motor (being called for short the SR motor), doubly salient permanent magnet motor, inductor machine is solid salient pole lamination, no coil winding and permanent magnetic material, and it is simple in structure firm, has obtained using comparatively widely under many occasions.Many applications such as accurate manufacturing technology (as high speed grinding machine, high-speed milling machine), centrifugal pump, compressor, flywheel energy storage, medicine equipment, Aero-Space require more and more higher to the rotating speed of drive motors, its rotating speed reaches several ten thousand rpms, even hundreds of thousands rpm.The windage that the rotor of salient-pole structure brings when low cruise is generally little, but the windage loss that the field spider of this type of motor brings when high-speed cruising is very surprising, and how designing rotor structure is that the design of high speed salient poles rotor motors must consider a problem with the windage that reduces rotor.Up to now, reduce the windage of field spider, the employing of usual method be the profile of tooth of optimizing rotor, reduce the groove height, increase arc transition face etc., but under very high rotating speed, above method is limited to the windage that reduces rotor; The measure that also has be increase rotor De Cao ?or increase filler etc. in rotor, increase the complexity of motor rotor construction, the technological requirement to clamping is very high simultaneously, add Zhuan Cao ?or during filler rotor structure intensity often do not reach requirement, in case come off, the formation accident, fail safe is not high.
Summary of the invention
The objective of the invention is to propose a kind of column-projection-polar composite rotor structure, do not change stator structure, be intended to do not reducing field spider firm prerequisite simple in structure, windage when effectively reducing the salient poles rotor motors operation, the while also helps the heat radiation and the vibration damping of rotor.
Technical solution of the present invention: the structure of column-projection-polar composite rotor is that the non-magnet material round metal ring plate that some external diameters are identical is inserted in the rotor of salient pole silicon steel plate core by the interval.Whole rotor pack adopts a clamping, by location hole or shaft key groove one-time positioning the rotor silicon steel sheet is not misplaced, and utilizes the anchor clamps once mounting in rotating shaft, makes field spider be formed with the column-projection-polar composite structure of narrow cavity like this.
Advantage of the present invention: the column-projection-polar composite rotor, after the rotor rotation, also will form the revolution eddy current in the narrow cavity after the separation, flow velocity helps reducing windage far below septumless; Metal spacer also increases the area of dissipation of rotor, helps the heat radiation of rotor; Same nonmagnetic metal partition also will will help reducing motor gas-gap magnetic field higher harmonic components producing damping action to the magnetic field of the pulsating of motor, help restraining torque pulsation and vibration.The solution of the present invention does not reduce field spider firm characteristic simple in structure, do not influence the effect of exerting oneself of motor, need not change stator structure in the course of processing, do not increase motor manufacturing cost and technology difficulty, easy to use, economic and reliable is particularly suitable for being applied in the high-speed applications of salient poles rotor motors.
