Abstract
An electric machine system includes a rotor core, a stator core disposed about the rotor core, an electric machine housing coupled to the stator core, a holding-cylinder disposed between the electric machine housing and the stator core, a first flange coupled to the electric machine housing at a first end of the holding-cylinder and a second flange coupled to the electric machine housing at an opposite end of the holding-cylinder.
Claims16
An electric machine system, comprising:
- a rotor core;
- a stator core disposed about the rotor core;
- an electric machine housing coupled to the stator core;
- a holding-cylinder disposed between the electric machine housing and the stator core;
- a first flange coupled to the electric machine housing at a first end of the holding-cylinder;
- and
- a second flange coupled to the electric machine housing and radially coupled to the holding-cylinder.

A stator core retention apparatus, comprising:
- a first flange integrally coupled to a holding-cylinder and configured to be axially coupled to an electric machine housing;
- and
- a second flange configured to be axially coupled to the electric machine housing and to receive a portion of the holding-cylinder.
A method for assembling an electric machine, comprising:
- axially positioning a stator core in a holding cylinder having a lip and a first flange;
- positioning the stator core in contact with the lip and secured by a retention device;
- coupling a second flange to an electric machine housing;
- coupling the holding-cylinder to the electric machine housing;
- and
- fastening the first flange to the electric machine housing to react electromagnetic torque and maintain axial position.
