US 6,664,682 B2 · Method and apparatus for securing a conduit box to a motor and motor incorporating same

Abstract

A technique for securing a conduit box to a housing of an electric motor is disclosed. The technique includes forming a hollow extension from a surface of the conduit box. The conduit box is placed on a motor frame so that the hollow extension is inserted into a hole in the motor frame that passes into the hollow interior of the motor frame. The hollow extension is plastically deformed inside the motor housing to a greater width than the diameter of the hole in the motor housing so that the conduit box cannot be removed from the motor housing. A stator is placed in the motor housing and wiring is routed from the stator to the interior of the wiring box through a passageway formed by the hollow extension.

Claims34

Dependent claims

An electric motor, comprising:

a motor housing comprising an exterior and a hollow interior, the motor housing having a hole therethrough from the exterior to the hollow interior, and
a conduit box comprising a portion that extends through the hole in the motor housing into the hollow interior, the portion being permanently plastically deformed to a configuration that blocks the conduit box from being withdrawn from the hole.

Dependencies are inferred from the claim text.
