Said shell (1) go up positioning means be from outer wall to stamping forming two positioning convex of inwall (11), stator (4) is positioned between two positioning convex (11).
Said shell (1) is gone up positioning means for to be installed in two locating studs on the shell (1), and stator (4) is between two locating studs.
The rear and front end of said shell (1) offers ladder heavy stand (12), and protecgulum (2) and bonnet (3) are inlaid in respectively in the ladder heavy stand (12) of shell (1) rear and front end.
Said protecgulum (2) and bonnet (3) punching press have the positioning ring towards shell (1) middle part, and the inwall of positioning ring and shell (1) is connected.
Said positioning ring is continuous loop or is interrupted discontinuous ring.
Said thin-wall metal case (1) is that extrusion structure or the welding of thin-wall metal convolution form.
The bottom of said shell (1) is provided with the motor cabinet (13) that play supporting role.
Said motor cabinet (13) welds or is threaded and is fixed on the bottom of shell (1).
Said motor cabinet (13) cross section is " several " font stamping part.
The good effect of the utility model is: shell is by extrusion structure thin-wall metal case or thin-wall metal convolution welding formation thin-wall metal case; With respect to carrying out mach shell after the tradition employing casting; Can simplify production technology; Enhance productivity and yield rate, therefore can effectively reduce production costs, be more suitable for producing in batches.On shell, be provided with positioning means, can prevent that the stator generation from moving axially, structure is more fastening, thereby improves working life.
