    • This invention aims at developing an Induction Motor that consumes less power than existing Induction Motors. An efficient Induction motor comprises a stator that includes three field windings and a rotor that includes rotor conductors short-circuited at both ends by end rings located at both ends of rotor. A field winding comprises a number of pairs of North pole and South pole. There are three full-wave rectifiers. Each of the three full-wave rectifiers converts a phase current of a three phase alternating current supply into a unidirectional current varying with time and delivers the converted current exclusively to a field winding. As a result, poles of the field winding generate fluctuating magnetic flux. A rotor conductor cuts said fluctuating magnetic flux thereby inducing an emf in said rotor conductor and consequently generating current in it. The direction of said magnetic flux and the direction of said current flowing in said rotor conductor are perpendicular to each other. Said rotor conductor moves in a direction perpendicular to both the direction of said magnetic flux and said rotor conductor current thereby rotates the rotor.
    • 本发明旨在开发一种比现有的感应电动机消耗更少功率的感应电动机。 一种有效的感应电动机包括一个包括三个励磁绕组的定子和一个转子,该转子包括位于转子两端的端环在两端短路的转子导体。 励磁绕组包括一对北极和南极。 有三个全波整流器。 三个全波整流器中的每一个将三相交流电源的相电流转换为随时间变化的单向电流,并将转换的电流专门传送到励磁绕组。 结果,励磁绕组的极点产生波动的磁通量。 转子导体切割所述波动的磁通量,从而在所述转子导体中引起电动势,从而在其中产生电流。 所述磁通量的方向和在所述转子导体中流动的所述电流的方向彼此垂直。 所述转子导体沿垂直于所述磁通量的方向和所述转子导体电流的方向移动,从而使转子旋转。
