Description
Technical field
The utility model relates to technical field of motors, particularly relates to a kind of high efficiency brake variable-frequency motor.
Background technology
Variable-frequency motor adopts the AC speed-regulating mode of " special variable frequency induction motor+frequency converter ", mechanical automation degree and production efficiency is greatly improved, is just replacing traditional mechanical speed governors and DC speed regulation scheme at present.Under existing technology, motor its rotor under powering-off state is still being rotated, then just slowly stop, in this case, the inconvenience in use is caused because the rotor in motor can not stop fast, even there is potential safety hazard, and can amount of heat be produced in variable-frequency motor, ventilate not and the unreasonable structure of friction element in addition, make useful life shorter.
Utility model content
For deficiency of the prior art, the utility model provides a kind of high efficiency brake variable-frequency motor.
To achieve these goals, technical solution adopted in the utility model is:
A kind of high efficiency brake variable-frequency motor, comprise housing, housing forward end is provided with front end housing, housing rear end is provided with rear end cap, is provided with stators and rotators in housing, is provided with the armature spindle that stretches out front end housing in rotor, front end housing is provided with ring flange, be provided with backbone sealing ring between front end housing and armature spindle, rear end cap is provided with brake and blower fan that armature spindle is stopped operating, described brake and blower fan are all fixed on rear end cap by hinged bolt.
Be arranged with fan housing outside brake on described rear end cap and blower fan, fan housing is fixed on rear end cap, be convenient to protection brake and blower fan injury-free, be also conducive to motor profile more attractive in appearance.
Described brake is electromagnetic brake, and concrete electromagnetic device has fast response time and the advantage such as structure is simpler.
The beneficial effects of the utility model: compared with prior art, the utility model covers the brake being provided with and armature spindle is stopped operating at motor rear end, brake and motor is made to be set to one, the braking to motor can be realized, avoid when not needing to rotate also in slow rotation, being also conducive to avoiding causing potential safety hazard; Rear end cap is provided with blower fan, the heat produced is distributed fast, extend the useful life of motor when the heat that brake and motor produced and machine operation; Brake and blower fan are all fixed on rear end cap by hinged bolt, mount and dismount simply convenient.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model;
Fig. 2 is side-looking direction of the present utility model schematic diagram.
