    • An electric machine (10) comprises a rotor (14a, b) having permanent magnets (24a, b) and a stator (12) having coils (22) wound on stator bars (16) for interaction with the magnets across an air gap (26a, b) defined between them. The bars (16) and coils (22) are enclosed by an annular stator housing (42a, b) that extends between the air gap. A chamber (52, 54, 56) is defined that incorporates cooling medium to cool the coils. The stator housing comprises two mating clamshells (42a, b) that mount the stator bars and coils in the machine. Each clamshell is molded from reinforced plastics and interconnected (optionally through one or more intermediate components). At least one clamshell has over-molded therein stator bar shoes that form part of said radial wall, and optionally one or more of the following components: cylindrical boss supports extending along the cylindrical outer wall part; connection studs that communicate electrically the chamber externally; stator coils; coolant inlet and outlet ports; and an outer race of a rotor bearing.
    • 一种电机(10)包括具有永磁体(24a,b)和定子(12)的转子(14a,b)和定子(12),该定子绕着定子线圈(16)缠绕线圈(22) 26a,b)定义在它们之间。 杆(16)和线圈(22)由在气隙之间延伸的环形定子壳体(42a,b)包围。 定义了一个包含冷却介质以冷却线圈的腔室(52,54,56)。 定子壳体包括将定子线棒和线圈安装在机器中的两个配合蛤壳(42a,b)。 每个蛤壳由增强塑料模制并互连(可选地通过一个或多个中间组件)。 至少一个蛤壳在其上模制成定子棒鞋,其形成所述径向壁的一部分,以及可选地一个或多个以下部件:沿着圆柱形外壁部分延伸的圆柱形凸起支撑件; 外部电连接室的连接柱; 定子线圈; 冷却剂入口和出口; 和转子轴承的外圈。
