Stator arrangement for an electric machine and an electric motor
First Claim
1. A stator arrangement for an electric machine comprising a stator body (10) having a number of stator teeth (14) between which stator slots (16) to receive stator windings are formed, and having an insulating layer (22) that is applied to the stator teeth (14) at least in the region of the stator slots (16) in which the stator windings are accommodated, the insulating layer (22) being integrally formed with a housing member (20) that is injection molded to the stator body (10), regions of the stator body (10) that do not receive any stator windings remaining at least partly uncovered.

Abstract
A stator arrangement for an electric machine comprising a stator body having a number of stator teeth between which stator slots to receive stator windings are formed, and having an insulating layer that is applied to the stator teeth at least in the region of the stator slots in which the stator windings are accommodated, the insulating layer being integrally formed with a housing member that is injection molded to the stator body, regions of the stator body that do not receive any stator windings remaining at least partly uncovered.

10. An electric motor having a stator arrangement comprising a stator body (10) having a number of stator teeth (14) between which stator slots (16) to receive stator windings are formed, and having an insulating layer (22) that is applied to the stator teeth (14) at least in the region of the stator slots (16) in which the stator windings are accommodated, the insulating layer (22) being integrally formed with a housing member (20) that is injection molded to the stator body (10), regions of the stator body (10) that do not receive any stator windings remaining at least partly uncovered, wherein
the stator body (10) has an inner rotor motor configuration having a back yoke ring (12) and stator teeth (14) projecting radially inwards from the back yoke ring (12), the insulating layer (22) and the housing member (20) being injection molded onto the stator body (10) such that the outside surface of the back yoke ring (12) remains uncovered, and wherein the housing member (20) has two housing sections (24, 26) on the opposing end faces of the stator body (10), the housing sections being substantially aligned with the back yoke ring (12).
