This paper presents a Switched Reluctance Motor (SRM) design procedure for an electric car drive system. Determination of geometrical dimensions, calculation of static parameters as well as the losses and efficiency is discussed. A dynamic SRM model is outlined and used to calculate the output characteristics of torque and power as functions of the speed.(More)
This paper deals with a novel design conception of Switched Reluctance Motor (SRM) for electrical vehicles as electrical mini truck. This design consists of segmented stator with toroid windings water cooled and the rotor has salient poles. The SRM dimensions are calculated on the base of input requirements. The static and dynamic parameters of SRM are(More)
The purpose of this work is to optimize a Switched Reluctance Motor (SRM) for an automotive application, specifically for a fully electric car. A new optimization approach is proposed. This unique approach transforms automotive customer requirements into an optimization problem, based on sound knowledge of a SRM theory. The approach combines an analytical(More)
The electrical drive systems used in automotive applications has to be both reliable and of high performance. To fulfill these demanding requirements a modular fault tolerant switched reluctance motor is proposed, which is controlled by means of an effective direct instantaneous torque controller. In the paper both the motor and the control system are(More)
This paper deals with the improvement of the switched reluctance motor's fault tolerant control for traction drives. The main purpose is to use a control technique which is able to retain the required speed for various load torques at minimal torque ripple also during one opened phase operation. The paper focuses on the comparative study of the current(More)
This paper deals with comparison of several control techniques for torque ripple minimization in drives with switched reluctance motor (SRM) under fault operation mainly if one phase is open. These techniques are: hysteresis control of phase current, PWM control, phase current profiling and direct instantaneous torque control. The basic principles of these(More)
This paper deals with the comparison of two different switched reluctance motors (SRM) designs and their losses and efficiencies from point of view of their using in electrical car. The first is an optimized three phase 18/12 SRM with concentrated windings and the second one is a new concept of SRM with segmented stator 12/8 SSRM. The design both of them is(More)
