A linear-motor stator assembly comprising a stator and an integral line reactor in one housing. The reactor has inductor coils which are connected in series with the stator windings to compensate for unequal inductances in the stator phases and balance the polyphase currents into the stator.

An electric motor, with a cage type rotor, of single or polyphase design having a multiple winding design in a single stator core. Where the primary winding and secondary winding having a magnetically and electric circuit configured alignment, that is a 0 difference in the respective magnetic alignments or the electric circuitry alignments. Yet completely separate and isolated from one another, electrically and physically. Wherein the prime operative function is configured in a series resonant and a parallel resonant circuit, using capacitors to produce a phase shift in the secondary winding. With the ability to be reconfigured to a secondary operative function, identical to the original winding and in all of its original operative designed functions.

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.

To reduce the number of mounted components in the power conversion device and drive device. Each high-side transistor and low-side transistor has an EGE-type structure of (emitter-gate-emitter type). A high-side driver includes a first pull-up transistor configured to apply a first positive voltage to a gate based on an emitter of the high-side transistor, and a first pull-down transistor configured to couple the gate to the emitter. A low-side driver includes a second pull-up transistor configured to apply a second positive voltage to the gate based on an emitter of the low-side transistor, and a second pull-down transistor configured to couple the gate to the emitter.

A drive system (1) having a unipolar machine (2) and a fuel cell (3) for supplying the unipolar machine (2) with electrical energy. The fuel cell (3) can be arranged in a ring shape around a rotor shaft (5) of a rotor (4) of the unipolar machine (2). The unipolar machine (2) can be provided in a motor vehicle (600) to supply a traction torque.

In induction motors, efficiency is improved and a maximum torque is increased. For a magnetic flux density of the stator pole for each phase of an induction motor, a circumferential magnetic flux density distribution is controlled to any distribution state, from a trapezoidal wave-like distribution close to a square wave to a sinusoidal distribution. In particular, motor efficiency in a range of low to medium rotations is improved. The motor structure is designed to reduce the leakage inductance of the rotor windings, and the motor and control thereof are optimized for each other. This increases the maximum torque of the motor more effectively. In addition, the high efficiency of the motor makes it possible to reduce the size of the drive circuit.
