   INTELLIGENT 8096-BASED MULTIMODE CONTROL OF A VARIABLE RELUCTANCE MOTOR DRIVE
By Patrick J. Roche; Michael G. Egan; John M. D. Murphy [View]
[Download]

Abstract: The switched or variable reluctance motor has significant advantages for industrial variable speed drive applications but control strategies are difficult to analyse and complex to implement due to machine non-linearities. In this paper, a comprehensive suite of variable reluctance motor performance simulation programs, based solely on the machine's flux linkage curves, is described. Optimum current-fed and voltage-fed control strategies can thus be predicted. An intelligent multimode 8096-based variable reluctance motor drive system, capable of imptementing these strategies, is presented.

   ATTRIBUTES OF SERVO DRIVE SYSTEMS WITH RELUCTANCE MOTORS
By Lothar Sack [View]
[Download]

Abstract: The reluctancemotor, which is fed by an inverter in a rotor orientated way, can be controlled comparably to a DC motor. Attributes of such a servo drive system are explained corresponding to features of the reluctancemotor and the transistor inverter. Signal processing for a large region of speed control including field weakening is represented as well as experimental results for two different types of reluctancemotors. For servo-applications torque pulsations as small as possible are necessary. A method for approximate calculation of these pulsations as function of the rotor position is shown for the reluctancemotor with segment-pole rotor.

   LOW AND HIGH SPEED OPERATION OF AN ORIGINAL 150 kW RELUCTANCE MOTOR WITH CURRENT SOURCE INVERTER SUPPLY
By R. Goyet; C. Nasr; L. Bouras; R. Guillet; L. Pierrat [View]
[Download]

Abstract: This paper presents the performances of a thyristor current source inverter connected with an original reluctance motor. The experiment has been developed in ORSAY at power levels up to 150 kW with a three-phase multistack reluctance prototype. Study analyses different conducting phases occuring in the inverter from lower to higher drive frequencies.

   SWITCHED RELUCTANCE DRIVES USING MOSFETs
By D. M. Sugden; R. J. Blake; S. P. Randall; J. M. Stephenson [View]
[Download]

Abstract: This paper describes the application of MOSFET switches to !ow-power, doubly-salient, switched reluctance drives. The basic principles of SR motors are introduced together with the range of possible power electronic circuits used to switch the motor currents. Design principles are discussed in the context of technical and economic factors and practical results are presented. The MOSFET-switched SR drive is shown to provide excellent performance and show great commercial potential.
