    • A method for forming a rotor for an induction motor includes providing a rotor core including a plurality of conductor bar grooves having first and second ends corresponding to first and second ends of the rotor core wherein the conductor bar grooves are progressively larger closer to the ends of the conductor bar grooves. The rotor core is placed into a casting mold, and molten metal is introduced into a first end of the casting mold. The molten metal flows from the first end of the casting mold through the plurality of conductor bar grooves to a second end of the casting mold. The molten metal solidifies to form conductor bars in the plurality of conductor bar grooves and to form shorting rings across exterior portions of the end elements within the first and second ends of the casting mold.
    • 一种用于形成用于感应电动机的转子的方法包括提供转子芯,该转子芯包括多个导体条槽,该多个导体条槽具有对应于转子芯的第一和第二端的第一和第二端,其中导体条槽逐渐地越靠近转子芯的端部 导体条槽。 将转子芯放置在铸模中,并将熔融金属引入铸模的第一端。 熔融金属从铸模的第一端通过多个导体条槽流到铸模的第二端。 熔融金属固化以在多个导体条槽中形成导体棒,并且在铸模的第一和第二端内的端部元件的外部部分形成短路环。
