Description
Technical field
The present invention relates to a kind of carpenter's spindle motor, particularly a kind of sealed AC permanent-magnet synchronous carpenter spindle motor.
Background technology
Motor the time must consider that in design foreign material such as extraneous dust get into motor internal vertically from motor output end, pollute the motor internal problem of environment.Present way is to adopt the sealing of " O " type circle at the motor front end.The shortcoming of this method: 1, it is a kind of contact seal, when rotating ratio is higher, and serious wear, the sealing of " O " type circle was lost efficacy easily.2, if select high performance wear-resisting O type circle for use, cost is higher.
Summary of the invention
The objective of the invention is to overcome above-mentioned deficiency of the prior art, a kind of sealed AC permanent-magnet synchronous carpenter spindle motor is provided.The present invention stops foreign material entering motor internals such as airborne dust effectively, obtain good sealing effectiveness, and it is simple in structure, and is with low cost, and very big dissemination is arranged.
For realizing above-mentioned purpose; The technical scheme that the present invention adopts is: sealed AC permanent-magnet synchronous carpenter spindle motor; Comprise main shaft, shell, stator module, p-m rotor assembly, preceding gland and rear pressing cover, the front and back end of said shell is separately installed with front-end bearing pedestal and rear bearing block, and said preceding gland is installed in the outer end of front-end bearing pedestal; Said rear pressing cover is installed in the outer end of rear bearing block; Said stator module is installed in the enclosure, and said p-m rotor assembly is installed on the main shaft and is corresponding with stator module, and the front end of said main shaft stretches out from shell; Said main shaft is connected with shell respectively with rear bearing with fore bearing on the rear bearing block through being installed in front-end bearing pedestal; The rear end of said main shaft is provided with encoder, and said encoder is connected with external driver, and the junction of said preceding gland and main shaft is provided with the restriction fore bearing along the axially movable locking nut one of main shaft; It is characterized in that: the part that said main shaft the past gland stretches out is equipped with rotary flywheel, and said rotary flywheel comprises pedestal and a plurality of moving blades that are provided with around pedestal.
Above-mentioned sealed AC permanent-magnet synchronous carpenter spindle motor, the arranged outside of said rotary flywheel has locking nut two.
Above-mentioned sealed AC permanent-magnet synchronous carpenter spindle motor, said moving blade is four.
The present invention compared with prior art has the following advantages: the present invention stops foreign material entering motor internals such as airborne dust effectively, obtain good sealing effectiveness, and it is simple in structure, and is with low cost, and very big dissemination is arranged.Said rotary flywheel comprises pedestal and a plurality of moving blades that are provided with around pedestal, through the rotation of moving blade, can effectively stop the foreign material such as dust near main shaft to get into motor internal, has effectively protected bearing, has purified the motor internal environment.
Through accompanying drawing and embodiment, technical scheme of the present invention is done further detailed description below.
