    A procedure is described for calculation of an auxiliary phase for a single-phase capacitor start motor. The size of wire, the number of turns, and the size of capacitor are determined to meet five restraints. These restraints are: required locked rotor torque, maximum allowable capacitor volts, maximum allowable locked rotor current, greatest current density in the auxiliary winding, and largest ...

    The equivalent circuit used for most single-phase motors with two windings is expanded to include motors having higher harmonics in the magnetic field, produced by concentric stator windings concentrated into stator slots. The mutual fields are described in equation form; how they occur in a single-phase induction motor is explained by a graphical interpretation. View full abstract»

    A method for speed control of a wound-rotor induction motor is described. The rotor is supplied from an inverter, with SCRs having the same output frequency as the rotor (sf1). The stator is connected to a 3-phase network with constant voltage and frequency. The motor works in the region s > 1, so that the rotor revolves against the rotating field. The inverter works at a higher frequency than tha... View full abstract»

    Parameter optimization of an induction machine is discussed from the viewpoints of the consumer and the national economy. The parameters thus determined ensure minimum cost but not normal machine properties. The object of the analysis was to determine the direction of change of the normal parameters which would ensure reduction in cost. Optimization was effected on seven principal parameters with ...

    The equations which describe the dynamic performance of unsymmetrical 2-phase induction machines are established, and an analog computer representation is developed from these equations. Computer representations of several single-phase machines including the split-phase, the capacitor-start, and the capacitor-start-capacitor-run types of induction motors are developed by extension and modification...

    The effectiveness of an analog computer in studying the performance of induction machinery is demonstrated with computer results which show the dynamic behavior of 2-phase and 3-phase machines during balanced and unbalanced operation. The computer simulation for these various modes of operation is conveniently obtained from the equations which describe the symmetrical induction machine in an arbit... View full abstract»

    In this paper, unbalanced operations of induction and synchronous machines are discussed. The current-voltage differential equations, referred to the moving reference axes ¿ and ß, are derived directly from the general equations of armature reaction and induced voltage. Kron's tensor transformation is used to develop a reciprocal system representing the actual machine under unbalanced operations... View full abstract»

    A 1-dimensional incompressible fluid model is used to show how two identical transverse-current MHD conduction generators, capable of self-excitation as dc generators, can be cross coupled magnetically to form a balanced 2-phase ac generator. The criterion for successful ac self-excitation is essentially the same as for successful dc self excitation; all reactive power is supplied by the generator... View full abstract»

    The direct measurement of stator winding copper temperatures in large electric machines is made possible with a miniature tunnel diode oscillator, mounted directly on the current-carrying conductor. A temperature-sensitive capacitor in the oscillator's resonant circuit causes the radiated signal frequency to change as copper temperature changes. This signal, radiated through the thickness of the w... View full abstract»

    Modern controlled semiconductors and their use in inverters and cycloconverters have resulted in the frequent application of induction machines in variable speed drive systems. Consequently, a need has arisen to develop simulation techniques for studying induction machines as components in controlled drives. An analog computer simulation together with its associated 2-phase voltage generator is de... View full abstract»

    The equivalent circuit of the induction motor has been modified by placing the iron loss resistance branch between r1 and x1 instead of in parallel with xM. By use of this circuit, the open circuit and stalled rotor tests are analyzed for the circuit parameters. The method given shows an improvement in obtaining X independently of r2 and in obtaining r2 itself. These improvements allow successful ... View full abstract»
