The invention discloses an electric machine component and a method to fabricate same. An electric machine rotor including a first stamped rotor lamination and a first stamped sheet of a material different than the first stamped rotor lamination is provided. The first stamped rotor lamination may define a pair of magnet pockets. The first stamped sheet may be coplanar with and scarf jointed to thefirst stamped rotor lamination to define a center bridge between the magnet pockets that has a magnetic permeability less than, and a mechanical strength greater than, the first stamped rotor lamination.

    本公开提供了“电机部件及其制造方法”。提供了一种电机转子,其包括第一冲压转子叠片和与所述第一冲压转子叠片的材料不同的第一冲压片材。所述第一冲压转子叠片可以限定一对磁铁凹口。所述第一冲压片材可以与所述第一冲压转子叠片共面并且嵌合到所述第一冲压转子叠片,以在所述磁体凹口之间限定中心桥,所述中心桥具有小于所述第一冲压转子叠片的磁导率和大于所述第一冲压转子叠片的机械强度。
