Abstract
The utility model provides a shaftless external rotor permanent magnet brushless DC motor, including bearing frame, stator winding, external rotor and driver, the external rotor cover is located stator winding's outside, the external rotor includes front end housing, rear end cap, casing, collar and a plurality of magnetic shoe, and fixed connection is on the front and back both ends of casing respectively for front end housing and rear end cap, and on the inner wall of casing was fixed in in the range of a plurality of magnetic shoes annular, the outside that the shell was located to the collar cover was used for adorning fan or impeller, stator winding includes stator core and around locating the last winding of stator core, stator core fold to be pressed and to be fixed on the bearing frame, and the rear end of bearing frame is connected with a driver shell, the driver set up in in the driver shell just the driver with stator winding connects, and stator winding and external rotor directly use the bearing frame to carry out the pressure equipment as the axis of reference, and the external rotor need not carry out the pressure equipment through the motor shaft, effectively solves the concentricity problem, simultaneously, reduces the motor shaft parts.
Description
Technical field
This utility model relates to technical field of motors, is specifically related to a kind of shaftless external rotor permanent magnetic brushless DC electric machine.
Background technology
Existing external rotor permanent magnetic brushless DC electric machine is usually provided with motor shaft, motor shaft is fixed on motor by two bearings, motor transmits mechanical energy by motor shaft, and the motor of this kind of structure has the disadvantage in that position deviation and the installation site etc. of bearing all can affect concentricity.
Utility model content
This utility model provides a kind of shaftless external rotor permanent magnetic brushless DC electric machine, solves and has axle external rotor permanent magnetic brushless DC electric machine to affect the defect of concentricity because of the position deviation of bearing and installation site etc. in prior art.
This utility model realizes above-mentioned technique effect and be the technical scheme is that
A kind of shaftless external rotor permanent magnetic brushless DC electric machine, including bearing block, stator winding, outer rotor and driver, described outer rotor is sheathed on the outside of described stator winding, described outer rotor includes drive end bearing bracket, rear end cap, casing, mounting ring and some magnetic shoes, described drive end bearing bracket and rear end cap are respectively fixedly connected with before and after casing on two ends, described some magnetic shoe annular array are fixed on the inwall of casing, and described mounting ring is sheathed on the outside of shell for installing fan or impeller；
Described stator winding includes stator core and the winding being set around on described stator core, described stacked stator core presses solidly and is scheduled on bearing block, the rear end of described bearing block connect have a drive enclosure, described driver to be arranged at described drive enclosure in and described driver be connected with described stator winding.
Further, the front end of described bearing block being provided with a bearing gear, described drive end bearing bracket fitted bearing is installed in bearing gear.
The beneficial effects of the utility model are: stator winding and outer rotor directly on the basis of bearing block axle press-fit, outer rotor need not be press-fited by motor shaft, effectively solves concentricity issues, meanwhile, reduces motor shaft parts.
