Description
Technical field
A kind of variable-frequency motor is the utility model is related to, particularly a kind of variable-frequency motor rotor.
Background technology
Rotor is the rotary part in motor, and it coordinates the conversion for realizing electric energy and mechanical energy with stator, is the weight of motor
Want building block.But rotating speed is very fast when current external rotor variable frequency motor works, and rotor case is occurred after long-term work
The situation of fracture, and because the big weight of existing rotor is laid particular stress on, the energy for causing motor to be lost in working is more, uses effect
Rate is low.Therefore, there is the problem of stress intensity is poor, and service efficiency is low in existing variable-frequency motor rotor.
Utility model content
The purpose of this utility model is, there is provided a kind of variable-frequency motor rotor.It has that stress intensity is good, service life length
The characteristics of.
The technical solution of the utility model：Variable-frequency motor rotor, including cover plate, cover plate are provided with groove, fixed on groove
There is injection molded flange, axle mount is provided with the inside of injection molded flange, side plate is provided with the outside of cover plate, side plate interior sides are provided with rotor magnet,
Cover plate is provided with reinforcement with side plate junction.
In foregoing variable-frequency motor rotor, shaft hole and locating slot, shaft hole inner side are provided with the inside of the axle mount
Triangular prism provided with some annular arrays.
In foregoing variable-frequency motor rotor, the profile of the groove is flaabellum shape, and groove is provided with ventilation with cover plate junction
Groove.
In foregoing variable-frequency motor rotor, the profile of the reinforcement is L-shaped.
In foregoing variable-frequency motor rotor, the rotor magnet is some profile identical curved bodies, and rotor magnet is in
Annular array is in side plate inwall.
In foregoing variable-frequency motor rotor, the injection molded flange is provided with fixed step with axle mount junction.
In foregoing variable-frequency motor rotor, 4 equally distributed inspection grooves are provided with the outside of the cover plate.
In foregoing variable-frequency motor rotor, the cover plate and the sheet metal that side plate is 2mm.
Compared with prior art, it is provided with groove and the reinforcement of L-shaped at cover plate, can effectively improve the stress of product
Intensity, rotor is set not cause to deform because of external force when motor works or be broken；Service life is grown；Because groove and reinforcement exist
Reinforcement in structure, product is used more frivolous sheet material under conditions of stress intensity is not influenceed, and reduce
Unnecessary gusset, the weight of product is reduced, so as to improve the service efficiency of motor.The utility model in injection molded flange and
Axle mount junction is provided with fixed step, and fixed step can make axle mount bear certain axial force, ensure to turn
Axle installed part will not be because of situation that the axial runout of machine shaft causes to loosen or dropped；The groove of ventilation slot and flaabellum shape is turning
During son rotation, air flow can be made, hot gas can discharge at ventilation slot, rotor is radiated rapidly, further increase rotor
Service life.
Brief description of the drawings
