Method for securing a motor housing to a motor assembly

摘要

A method for securing a motor housing to a motor assembly is provided. One application of the method creates a motor housing to secure and protect a motor assembly. A flat metal sheet is shaped, so that deformable ends of the sheet are incrementally rolled to form a split annulus approximating the outer circumference of a motor assembly. Once the split annulus is formed, the ends are elastically deformed to facilitate inserting the motor into a hollow portion of the split annulus. After the motor is inserted, the ends may be joined by welding one to the other. This type of housing secures the motor assembly through a crimping force applied by the housing. Alternately, the ends may be welded together and to the motor assembly itself, thereby forming a strong support structure between the housing and the motor assembly.

主权项

1. A method for securing a motor housing to a motor assembly comprising:
inserting a motor assembly into a cylindrical hollow tube, wherein the tube has a longitudinal slit defined by edges of the tube; manipulating said edges to accommodate the inserted motor assembly; and securing the motor housing in place on the motor assembly by welding said manipulated edges to each other and to a motor stator associated with the motor assembly.
