Embodiment Construction

[0022] By way of example and not limitation, a detailed description of one or more embodiments of the disclosed apparatus and method is presented herein with reference to the accompanying drawings.

[0023] First refer to figure 1 , an electric motor according to an exemplary embodiment is generally designated 10 . The electric motor 10 includes a housing 14 having an outer surface 16 and an inner surface 18 defining an interior 20 . The housing 14 includes a first end wall 23 and an opposing second end wall 25 . One of the first end wall 23 and the second end wall 25 may be integrally formed with the housing 14, while the other of the first end wall 23 and the second end wall 25 may be removable. Of course, both the first end wall 23 and the second end wall 25 may be removable. The first end wall 23 includes an opening 27 .

[0024] The electric motor 10 includes a rotor 40 rotatably mounted in the interior 20 . The rotor 40 includes a shaft 43 that supports a rotor core...

Abstract

An electric machine includes a housing, a rotor rotatably mounted in the housing, and a stator fixedly mounted to the housing. The stator includes a stator core and a plurality of stator windings supported by the stator core. The stator core surrounds the rotor. A bus bar including a plurality of conductive members is coupled to the stator winding, and an insulating cover extends through at least a portion of the conductive members. A bracket is coupled to the bus bar and one of the stator core and the housing, the bracket supporting the bus bar in the housing.

Description

[0001] Cross-application of related applications [0002] This application claims the benefit of the earlier filing date of US Application No. 62 / 950,730, filed December 19, 2019, the entire disclosure of which is incorporated herein by reference. technical field [0003] Exemplary embodiments relate to the field of electric machines, and more particularly, to brackets for securing a bus bar to a stator of an electric machine. Background technique [0004] The electric machine includes a stator having stator windings mounted to a housing and a rotor including rotor windings that rotate relative to the stator. The stator windings can be energized to exert a rotational force on the rotor, or the rotation of the rotor can induce currents in the stator windings. In the first mode of operation, current flows to the stator windings. In the second mode of operation, current flows from the stator windings. Thus, the stator windings are connected in a selected pattern and are prov...
