Summary of the invention
the utility model purpose is: a kind of brushless electric machine of installing simply and having ball bearing structure is provided.
The technical scheme of
the utility model is: a kind of brushless electric machine with ball bearing structure, and it comprises stator core and is fitted in the stator holder on the stator core; Said stator holder has integrated clutch shaft bearing chamber and is installed in the first indoor rolling bearing of clutch shaft bearing.
On the basis of technique scheme, it further comprises attached technical scheme:
It further comprises
and injection moulding of stator core one and the stator skeleton that is used to insulate.
said stator skeleton has integrated second bearing chamber and is installed in second rolling bearing in second bearing chamber.
said stator holder comprises a protuberance that passes stator core center and inner hollow, and wherein first and second rolling bearing is positioned at the two ends of protuberance.
The utility model advantage is:
the utility model adopts the mode of integral molded plastic to insulate through designing stator core, and bearing chamber that is used to install ball bearing of moulding on the plastic skeleton of injection mo(u)lding has removed the insulating trip in the original structure and used simultaneously; Be fitted on the stator core simultaneously; And be used for fixing the stator holder moulding another one bearing chamber of stator core, and simple in structure, be convenient to install; Electrical machinery life is long, and motor stabilizing property and reliability are high.
