Stator having housing-integrated bus bars and internal cooling jacket

An electric machine, comprising:

• a motor housing having a periphery thereof and an interior surface of the periphery, the motor housing configured to house a rotor that rotates about an axis of rotation therewithin;
• at least one stator means for conducting an electrically current and generating a magnetic field;
• electrically conductive means embedded in the interior of the periphery of the motor housing, the electrically conductive means for conducting an electric current to the stator means, the electrically conductive means further radially protruding internally from the interior of the periphery of the motor housing perpendicular to the axis of rotation of the rotor;
• and
• the stator means directly connected to at least one bus bar,
• wherein the electrically conductive means further for providing a surface with which the stator means can electrically connect thereto in a radial manner about the axis of rotation for the rotor.

A method of manufacturing an electric machine, comprising the steps of:

• forming a motor housing having a periphery thereof and an interior surface of the periphery, the motor housing configured to house a rotor that rotates about an axis of rotation therewithin;
• embedding one or more electric bus bars in the interior of the periphery of the motor housing, each bus bar radially protruding internally from the interior of the periphery of the motor housing in the direction of the axis of rotation of the rotor, wherein the embedding of each electric bus bar is within the interior of the periphery of the motor housing at predetermined intervals thereby providing a surface with which at least one stator coils can electrically connect to at least one bus bar in a radial manner about the axis of rotation for the rotor;
• and
• connecting at least one stator coil directly to at least one bus bar.
