    Abstract: 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.

    Abstract: The present invention belongs to the technical field of alternating current induction servo motors, and particularly relates to a rotary-type induction servo motor with a constant-output-torque by using uniform magnetic fields and a linear-type induction servo motor with a constant-output-force by using uniform magnetic fields. The present invention has main features that the rotary-type induction servo motor or the linear-type induction servo motor is composed of N independent motor units; each independent motor unit has the same or similar structure, and is powered by single-phase alternating current; and the N independent motor units have an equal voltage magnitude of power supply, but voltage phases are different and form an arithmetic progression. In an independent motor unit of the rotary-type induction servo motor with a constant-output-torque by using uniform magnetic fields, the stator magnetic conductive silicon steel is simple in structure, and the winding manner of stator excitation windings is simple, similar to a multilayer solenoid type; rotor induction excitation windings are powered through induction, and no slip ring and related wearing parts are used. The rotary-type induction servo motor disclosed here can be operated at fixed voltage frequency, and in this case, the output torque and the voltage magnitude of power supply are in direct proportion, so the output torque can be controlled by adjusting the voltage magnitude. The motor does not adopt permanent magnetic materials, and has many merits including simple structure, good torque characteristic, simple controller design and high control precision. And meanwhile, based on the same principle, a linear-type induction servo motor with a constant-output-force by using uniform magnetic fields can be evolved from the rotary-type induction servo motor.

    Abstract: To maximize a power consumption reduction effect in a case of using a high-efficiency induction motor, when a conventional induction motor is changed to a high-efficiency induction motor, a mechanical device including an induction motor and a speed reduction mechanism related to the present invention increases the reduction ratio of the speed reducer such that the rotation speed of the mechanical device is equal to that in a case of using a conventional induction motor and thus the output of the mechanical device is made equal to that in a case of using a conventional inductor motor; therefore, the load conditions of the mechanical device such as a pump and a fan can be made equal to those in a case of using a conventional induction motor. Accordingly, the power consumption reduction effect by improving the efficiency of the induction motor can be maximized.
