    A variable-speed drive using a doubly salient variable reluctance motor, because of its ability to operate efficiently from unidirectional winding currents, enables the number of main switching devices in the inverter to be halved, yielding a very economical brushless drive. The drive is analysed using a linear model for the motor, yielding phase-current waveforms which enable an economical design... View full abstract»

    The paper describes a control system for 4-quadrant operation of induction motors with characteristics suitable for crane hoist duty. The control system is based on a combination of stator-voltage control and rotor chopping. A thyristor stator-voltage regulator is used to provide a means of motor-speed closed-loop control. The regulator automatically reverses the phase rotation for plug braking or... View full abstract»

  • Control of a Naturally Commutated Inverter-Fed Variable-Speed Synchronous Motor

    Publication Year: 1979, Page(s):199 - 204

    This paper describes the design and construction of the control circuits of a naturally commutated current-source inverter feeding a synchronous motor to give a variable-speed drive. The main contributions of the paper deal with the circuits required to control the inverter from rotor position, and to control the system for all modes of operation including regenerative braking. The performance of ... View full abstract»

  • Steady-State Line-Line Loading of the Synchronous Machine: Exact Solution

    Publication Year: 1979, Page(s):205 - 212

    The mathematically exact solution for the steady-state line-line short circuit of the basic synchronous generator is developed from first principles and extended to include the effects of saliency and dampers. The analysis is applicable to steady-state line-line loading and also to the performance of the single-phase machine. The solution is checked by comparison with the numerical step-by-step so...

  • Characteristics of a Heteropolar Linear Synchronous Machine with Passive Secondary

    Publication Year: 1979, Page(s):213 - 218

    Test results are presented for a novel form of heteropolar linear synchronous machine. The results show that the machine is capable of providing both thrust and lift force at relatively high efficiencies and power factors. A simple control scheme is described that enables independent variation of lift and thrust to be made. This is accomplished by the use of `constant-current┬┐┬┐ supplies and operat...
