Embodiment Construction

[0040] The embodiments of the invention described herein are not intended to be exhaustive or to limit the invention to the precise form disclosed. On the contrary, the embodiments selected as described have been chosen to enable those skilled in the art to practice the invention.

[0041] Start referencing figure 1 , A perspective view of an exemplary parallel stator assembly 10 for use in the electric machine 12 is shown. As described in more detail herein, the stator assembly 10 is considered to be connected in parallel because its phase windings are interconnected in parallel. The stator assembly 10 includes an insertion end 14 and an opposite end or connection end 16. When the electric machine 12 is used as a motor (such as a starter motor or a traction motor), it includes a stator assembly 10 that is operatively coupled to a rotor (not shown) through a magnetic field to convert electrical energy into mechanical energy. In a similar manner, the electric machine 12 can also...

Abstract

A spacer for supporting conductors in a stator assembly of an electric machine includes a plurality of positioning elements cooperating with various conductors in the specials region of the winding arrangement. The spacer illustratively includes an insulating body formed of an electrically non-conductive material and including surfaces facing axially inwardly for contacting short conductors and crossover pockets for receiving crossover conductors which electrically connect an inner winding set and an outer winding set. The spacer further illustratively includes phase lead pockets facing axially outwardly for receiving a terminal phase lead conductor.

Description

Technical field [0001] The present invention generally relates to a motor, and more specifically, to a gasket for electrically insulating various conductors formed in the winding arrangement in the stator assembly of the motor. Background technique [0002] The electric motor can include various uses related to the power transmission system of an automobile. For example, a conventional automobile may use an electric motor as a starter motor for an internal combustion engine or as an alternator to generate electricity and transmit power to vehicle accessories and / or to charge vehicle batteries. [0003] An exemplary electric machine includes a rotor and a stator. The stator is composed of stator laminations or stator cores and a plurality of electrical conductors, or windings, which are inserted in the stator laminations. The windings are interconnected (for example welded together) or joined at the welded end turns to form the circuit required for the operation of the motor. In ...
