Description
Technical field
The present invention relates to motor, more particularly to a kind of permanent magnetic servo motor rotor and its manufacture method.
Background technology
Servomotor is because of its good speed adjustment features, the advantages of precision is high, is widely used in lathe, textile industry etc..And watch
Take and use surface-mount type more motor rotor construction, glue is added on rotor core surface using magnet steel more than surface-mounted rotor structure, so
Add glass fibre protection band or steel bushing to fix outside magnet steel afterwards, motor is prevented when running at high speed, due to centrifugal action, magnetic
Loosening or obscission occurs in steel.So make cumbersome on assembly technology in rotor using glass fibre protection band, it is time-consuming
Arduously, production cost is increased；And eddy-current loss can be produced using steel sleeve structure, electric efficiency is reduced, motor performance is influenceed, both
Effect is not so good.

Oxygen glue.
As a further improvement on the present invention, the end face of the rotating shaft iron core integral member is relative with the end face of the magnet ring
Together.
As a further improvement on the present invention, the magnet ring is sintering rubidium iron boron magnet ring.
Present invention also offers a kind of manufacture method of permanent magnetic servo motor rotor, comprise the following steps：
S1, one layer of anaerobic adhesive of uniform coating on the external peripheral surface of rotating shaft iron core integral member；
S2, the magnet ring not magnetized is assembled in rotating shaft iron core integral member, forms permanent magnetic servo motor rotor；
S3, permanent magnetic servo motor rotor is put into baking oven baking, cooling, it is ensured that magnet ring bonds jail with rotating shaft iron core integral member
Gu；
S3, overall magnetize is carried out to permanent magnetic servo motor rotor.
The beneficial effects of the invention are as follows：By such scheme, using rotating shaft with iron core integrative-structure, rotor, iron are eliminated
Without protective cases such as glass fibres outside the assembly process of core, magnet ring, assembly relation is simple, saves production cost；It is not required to simultaneously
To increase steel bushing protection device etc. outside magnet ring, eddy-current loss will not be produced；Only need to outside rotating shaft iron core integral member
The magnet ring not magnetized, is then enclosed in rotating shaft iron core integral member by uniform gluing, treats that rotor is toasted in an oven and firmly may be used
Lean on, you can entirety is carried out to rotor and magnetized, desired field waveform is filled into, and the rotor structure can make air gap be made smaller,
So as to improve permanent magnet utilization rate.
