A method for making a unit-bearing motor wherein a drawn steel cup-shaped frame has a base and a longitudinal axis, an elongated metallic post is shaped with an outer cylindrical mounting surface at a first end and disposed in a coaxial aperture in the frame base, an annular shoulder is formed on the metallic post adjacent the outer mounting area, and this shoulder abuts a mounting area surrounding the coaxial base aperture. A jig is used to locate the post coaxially in the cup-shaped frame, with the post first end in the base aperture and the shoulder abutting the mounting area, and then a brazing liquid, such as silver solder, is flowed into the space between the post and the base and allowed to harden to secure the post in the frame. The post has a journal bearing aperture to provide a unit bearing for a rotor cooperating with the stator carried in the frame. |
