Abstract
A method of assembling a motor for use in a machine is disclosed. The motor includes an axially extending rib protruding radially outwardly from the radially outer surface of the core. The motor further includes a groove-defining portion that defines an axially extending groove receding radially outwardly from the radially inner surface of the shell. The motor assembly method includes the steps of: (a) heating at least the groove-defining portion of the shell; (b) rotationally orienting the core and the shell so as to axially align the rib and the groove; (c) axially receiving the core within the shell such that the rib is received in the groove without interfering with the groove-defining portion; and (d) cooling at least the groove-defining portion so that the rib is fit within the groove via an interference fit.
