Patent number: 9866079Abstract: An electric motor includes a rotor and a wound stator structure. The stator structure includes a housing, a laminated stator core and windings wound around the stator core. The laminations of the stator core have an annular body and a plurality of teeth extending radially inwardly from the annular body. Projections and recesses are formed at the outer edge of the annular body. When assembled, the recesses of one lamination are aligned with the projections of an adjacent lamination such that when fitting the stator into the housing the projections may be deformed into an axially adjacent recess by contact with the housing. Thus the stator core contacts the housing at discrete locations.Type: GrantFiled: December 28, 2015Date of Patent: January 9, 2018Assignee: Johnson Electric S.A.Inventors: Yong Bin Li, Long Shun Jiang, Xian Chun Fan, Ping Wang
