Description
Technical field
The utility model is related to field of motor manufacturing, specifically a kind of driving motor rotor press plate.
Background technology
Permanent magnet synchronous motor is current domestic new energy motor field main product, and motor has high efficiency, high torque used
The features such as amount ratio, high-energy density.Its rotor structure mostly uses silicon steel sheet tinertoy, and centre is packed into permanent magnetic steel, and rotor tip is used
Pressing plate compresses, to prevent high rotating speed lower magnetic steel from throwing away, silicon steel sheet deformation.In addition, motor in rotary course, is put down if rotor is dynamic
Weighing apparatus property is unqualified, and rotor can be made by force couple role, generates around axis oscillating phenomenon, damages motor.Rotor dynamic balancing is typically
It is adjusted in rotor end plates.Conventional rotors pressing plate is generally made of steel pressing plate and brass sheet, and structure is relative complex, rotation
When noise it is larger.
Invention content
A kind of driving motor rotor press plate is provided the purpose of the utility model is to overcome the above-mentioned insufficient of the prior art,
Rotor can not only be compressed, carry out dynamic balancing adjustment, moreover it is possible to effectively reduce motor overall noise.
The technical solution of the utility model is：Including circular pressing plate ontology, pressing plate body central is equipped with and is used for and motor
The mounting shaft hole of axis interference fit；The mounting shaft hole longitudinal section is horn-like structure, the big one end of mounting shaft hole diameter and pressure
The bottom surface of plate ontology is concordant, and the central axis of mounting shaft hole is in the plane where pressing plate ontology bottom surface；The pressing plate ontology
Bottom surface is equipped with the groove of annular；The thickness of the pressing plate ontology is 3 ~ 5mm, a diameter of 100 ~ 350mm of pressing plate ontology；The peace
The pore wall thickness for filling axis hole is identical as the thickness of pressing plate ontology, a diameter of 20 ~ 60mm of mounting shaft hole；The mounting shaft hole diameter
The diameter ratio of big one end and the small one end of diameter is 1：0.6.
The pressing plate ontology uses magnetic separator punch forming.
The horn-like structure of the mounting shaft hole forms one with pressing plate body upper surface junction in the mounting shaft hole and inclines
Oblique annulus.
The gradient of the annulus is 30 °.
A diameter of 50 ~ 200mm of the groove, width are 0.5mm.
The beneficial effects of the utility model are：Simple in structure, using stainless steel material, density is higher, and intensity is good, moves flat
The duplicate removal effect that weighs is good and has magnetism isolating effect；Mounting shaft hole, using being interference fitted, is conducive to compress rotor punching with motor shaft, can
It is compressed for rotor end-face；Rotor punching lightening hole can be closed, reduce the noise generated in rotor rotation process.
