Abstract: An electric machine assembly includes a housing having a first portion and a second portion. The electric machine assembly also includes a midframe coupled between the first and second portions such that the mid-frame and the first portion partially define a first compartment and such that the mid-frame and the second portion partially define a second compartment. A terminal box is coupled to the mid-frame and configured to house a first plurality of electrical components. A stator is positioned within the first compartment and a second plurality of electrical components positioned with the second compartment. The stator and the second plurality of electrical components are electrically coupled by a first plurality of wires extending through the mid-frame, and the first plurality of electrical components are electrically coupled to the second plurality of electrical components by a second plurality of wires extending through the second compartment and into the terminal box.

Abstract: An electric machine includes a housing having an air intake, an air outlet, and defining an air passage therein. The air passage includes a first channel extending from the air intake in a radial direction and a second channel extending in the radial direction to the outlet. The electric machine further includes a motor assembly positioned within the housing that includes a shaft that rotates about a rotational axis that is generally perpendicular to the radial direction. The electric machine further includes an electronics assembly within the housing interior and a heat sink positioned at least partially within the air passage and thermally connected to the electronics assembly. Operation of the motor assembly draws an ambient airflow into the air passage in the radial direction through the air intake, directs the airflow along the heat sink, and exhausts the airflow through the air outlet in the radial direction.

Abstract: A motor assembly having a rotational axis includes a motor housing comprising a plurality of cooling openings extending therethrough and defining a chamber. The motor assembly also includes a stator fixedly coupled to the motor housing and positioned within the chamber. A rotor is coupled to at least one of the motor housing and the stator, wherein the rotor is configured to rotate about the axis and is positioned within the chamber. The motor assembly includes a fan having a first inlet side on a first axial side of the fan and a second inlet side on a second, opposing, axial side of the fan. The fan is configured to draw cooling air in a first direction through the at least one cooling opening into the first inlet side, and the fan is also configured to draw cooling air in a second, opposite direction into the second inlet side.

Abstract: An electrical switch for an electric machine includes body, a stator fixedly secured to the body and a rotor. The actuator includes a first member securable to the rotor and rotatable with it. The actuator also includes a second member, a first electrically conductive member cooperates with the second member. The actuator also includes a second electrically conductive member. The second electrically conductive member is spaced from said first electrically conductive member when said first electrically conductive member is in the first axial position and electrically engaged with said first electrically conductive member when said first electrically conductive member is in the second axial position.
