    • An uncluttered secondary induction machine (100) includes an uncluttered rotating transformer (66) which is mounted on the same shaft as the rotor (73) of the induction machine. Current in the rotor (73) is electrically connected to current in the rotor winding (67) of the transformer, which is not electrically connected to, but is magnetically coupled to, a stator secondary winding (40). The stator secondary winding (40) is alternately connected to an effective resistance (41), an AC source inverter (42) or a magnetic switch (43) to provide a cost effective slip-energy-controlled, adjustable speed, induction motor that operates over a wide speed range from below synchronous speed to above synchronous speed based on the AC line frequency fed to the stator.
    • 整体二次感应电机(100)包括安装在与感应电机的转子(73)相同的轴上的整流式旋转变压器(66)。 转子(73)中的电流与变压器的转子绕组(67)中的电流电连接,该电流不与定子次级绕组(40)电连接,而是磁耦合。 定子次级绕组(40)交替地连接到有效电阻(41),AC源逆变器(42)或磁性开关(43),以提供经济有效的滑动能量控制的可调速度感应电动机,其操作 基于馈送到定子的交流线路频率,从低于同步速度到高于同步速度的宽速度范围。
