Motor housing

摘要

A motor housing includes a central body having a central cavity region configured to receive an electric motor. Also included is a first end portion having a first inner surface that defines a first internal cavity region configured to receive a first end winding of a stator of the electric motor, wherein the first internal cavity region comprises a first radius defined by a distance from a main axis of the motor housing to the first inner surface. Further included is a second end portion having a second inner surface that defines a second internal cavity region configured to receive a second end winding of the stator, wherein a ratio of the first radius to a first end portion wall thickness ranges from 19.89 to 27.85.

1. A motor housing comprising:
a central body having a central cavity region configured to receive an electric motor and disposed about a main axis defined by the intersection of a first plane and a second plane disposed orthogonal to the first plane; a first end portion having a first inner surface that defines a first internal cavity region configured to receive a first end winding of a stator of the electric motor, wherein the first internal cavity region comprises a first radius defined by a distance from the main axis of the motor housing to the first inner surface; a second end portion having a second inner surface that defines a second internal cavity region configured to receive a second end winding of the stator, wherein the second internal cavity region comprises a second radius defined by a distance from the main axis of the motor housing to the second inner surface; and wherein a ratio of the first radius to a first end portion wall thickness ranges from 19.89 to 27.85, wherein a ratio of the second radius to a second end portion wall thickness ranges from 8.52 to 9.78, the radius to wall thickness ranges spacing the first and second inner surfaces from the respective end windings of the stator to avoid damaging the motor housing during installation or removal of the electric motor, wherein a ratio of a second end portion wall thickness to the first end portion wall thickness ranges from 1.93 to 3.10, the distinct wall thicknesses providing distinct thermal insulation requirements.
