An analysis of the induction machine

Electrical Engineering, 1938

THERE has long been a need for a means of evaluating the performance of induction motors under transient conditions, as when driving pulsating compressor loads. The familiar equivalent-circuit analysis is inadequate to determine the effects of pulsating speeds, and the more complete analysis of S. J. Levine<sup>1</sup> is somewhat inconvenient, since the rotating axes assumed lead to involved equations. Probably ...


Dampins and synchronizing torques of power selsyns

Electrical Engineering, 1945

SELSYN systems are used very widely as power drives and as indicators when it is necessary to have the position of an element correspond synchronously with that of a controlling element which is remotely located. The receiver Selsyn is used either directly as the output driving motor or as an input to a following power-amplifying stage of a control system.∗In ...

Fundamentals of Electric Power Engineering: From Electromagnetics to Power Systems, None

The synchronous machine is a three-phase machine, able to exchange power with a three-phase network. Although it can also operate as a motor (absorbing electric energy) in the majority of applications, it is used as a generator (delivering electric energy). The vast majority of power stations generate electricity in three-phase form, using synchronous machines. Synchronous machines used in power stations, ...

  • An analysis of the induction machine

    THERE has long been a need for a means of evaluating the performance of induction motors under transient conditions, as when driving pulsating compressor loads. The familiar equivalent-circuit analysis is inadequate to determine the effects of pulsating speeds, and the more complete analysis of S. J. Levine<sup>1</sup> is somewhat inconvenient, since the rotating axes assumed lead to involved equations. Probably the most convenient approach is to be found in the stationary-axis method so successfully applied by R. H. Park<sup>2</sup> to the analysis of salient-pole synchronous machines.

  • Dampins and synchronizing torques of power selsyns

    SELSYN systems are used very widely as power drives and as indicators when it is necessary to have the position of an element correspond synchronously with that of a controlling element which is remotely located. The receiver Selsyn is used either directly as the output driving motor or as an input to a following power-amplifying stage of a control system.∗In the study of such Selsyn systems and of the control systems of which Selsyn systems form one of the links, it becomes necessary to determine the hunting-torque characteristics of these machines (that is, the damping and synchronizing torques for small oscillations) as affected by speed, load, oscillation frequency, and, of course, the various design factors. The direct calculation of these hunting-torque characteristics is difficult, but within the past few years methods have been developed whereby the machine performance may be represented by equivalent static electric circuits. The purposes of this paper are: 1. To show how these hunting-torque characteristics can be simply determined by measurements on equivalent electric circuits set up on an a-c network analyzer. 2. To present some of the results of studies made of specific Selsyn systems.

  • Synchronous Machines and Drives

    The synchronous machine is a three-phase machine, able to exchange power with a three-phase network. Although it can also operate as a motor (absorbing electric energy) in the majority of applications, it is used as a generator (delivering electric energy). The vast majority of power stations generate electricity in three-phase form, using synchronous machines. Synchronous machines used in power stations, therefore, not only generate active power for the loads, but also contribute to supplying the loads with the needed reactive power. In a synchronous machine rotor, therefore, the insertion of permanent magnets (PMs) can have the same effect as a DC-fed coil with a fixed current flowing in it. In recent years, electronic devices have appeared that are able to convert constant frequency sources into variable frequency, thus allowing modification of voltage and frequency characteristics of a three-phase source.

  • DC Motor Drives

    The introduction of power electronics greatly improved the performance of DC motor drives, enabling them to overcome the inherent limitations of electromechanical drives used in traction vehicles, that is, low efficiency and torque ripple during the start‐up phase. The motors deliver their nominal power in the connection that provides higher voltage to the terminals, that is, normally at the nominal voltage. In no‐load operation of the motor, that is, with no induced current flux, it is necessary to separate the armature circuit of the motor field winding and power the latter with current. The speed of the rotor can be varied by varying the power supply voltage, varying the flux by acting on the mmf field, produce an additional voltage drop by a rheostat in series with the armature circuit. Most suitable forms of magnetization characteristics of the motor can be obtained with an appropriate rating of the magnetic circuit of the inductor.

  • Analysis of A-C servomotors operated from unbalanced nonsinusoidal voltage sources and nonlinear discontinuous source impedances

    MANY ANALYTICAL studies directed at the predetermination of output characteristics of a-c servomotors have been based on the assumptions of constant-source impedance and sinusoidal excitation. Under these assumptions, the method of symmetrical components serves admirably, particularly when steady-state characteristics are desired, and in cases where the duration of the mechanical transients makes the electrical transients insignificant.

  • (a) Induction motors

    A. E. Averrett: Regarding the separation of copper losses, there seems to be a tendency on the part of some users to want bar-wound stators on account of the ease of repair. You can make a bar-wound stator with rather deep bars, but if you have a rotor that is bar-wound also and assume that the losses are practically all in the rotor, these will disappear at synchronous speed and you will apparently have a more efficient machine than you really have, if all the losses are taken into consideration. But you can actually get the loss by taking out the rotor and measuring the impedance of the stator alone by wattmeters, which will show up the losses correctly if the tests are made carefully.

  • DTFC Based Indirect Matrix Converter Using Active Flux Concept for IPMSM Drive

    An improved direct torque and flux control (DTFC) scheme based on active flux concept for interior permanent magnet synchronous motor (IPMSM) using indirect matrix converter (IMC) is presented in this paper. Active flux concept changes rotor with magnetic poles saliency to nonsalient ones. Rotor position and speed estimation are simplified significantly, because rotor position and active flux position are identical. Torque and flux are controlled independently using PI controllers and four-step switching is used in rectifier bridge of IMC to reduce torque ripple associated with DTC. Removing bulky capacitor of DC link in IMC results in reduced volume and size of converter. Combination of benefits of IMC and DTFC can be achieved using this scheme. Low torque and flux ripples, constant switching frequency, unity power factor regardless of load power factor, wide speed range and low THD are features of proposed scheme.
