Performance Calculation of SR Motors for Optimum Design and a Washing Machine Application

This paper aims to develop an approach for performance calculation of an SR motor, which is suitable for use within mathematical design optimization. For this reason the requirement is to develop procedures, which are both accurate and fast. The procedures adopted here rely on flux-linkage-current-position curves of the motor. A series of tests are carried out on a test motor. The results are compared with estimations from the developed algorithms. It is shown that the current waveform, torque-speed curve, total loss and efficiency can be accurately calculated using the proposed algorithms, provided that the motor data is accurate. The computation time required is about 0.7s and in this respect much depends on the procedures used for accessing and processing the motor data.


Effects of control parameters on SRM performance: A parametric search
Bizkevelci, E.; Özlü Ertan, Hatice Gülçin; Leblebicioğlu, Mehmet Kemal (2007-09-12)
This paper investigates the effects of the SRM control parameters on torque ripple and efficiency. The average shaft torque, torque ripple and the torque per ampere variation of the motor are observed at different turn-on and conduction angles. The study is performed using simulation software developed by the authors. Some experimental results are presented which indicate that the software promises to be accurate. The findings of the study are presented to give an idea about the optimum switching strategy t...

Uğur, Mesut; Keysan, Ozan (2018-10-25)
In this study, design procedure of an Integrated Modular Motor Drive (IMMD) is presented focusing on high power density. The design is based on a permanent magnet synchronous motor (PMSM) and GaN FETs. Fractional slot concentrated windings are used on the stator. Slot/pole combination and winding configuration is selected based on having low cogging torque and high winding factor. An extended motor drive inverter topology is proposed where 2-level voltage source inverters are connected both in series and pa...

Direct Torque Control of a 4-Phase Switched Reluctance Machine
Petrus, V.; Pop, A. -C.; Martis, C. S.; Iancu, V.; Gyselinck, J. (2011-09-10)
Due to its doubly salient structure and highly nonlinear behavior, the Switched Reluctance Machine (SRM) operates with very high torque ripple. To overcome these inconveniences different average and instantaneous torque control techniques were developed. This paper presents an instantaneous torque control technique named Direct Torque Control (DTC) implemented on a 4-phase, 8/6, 0.75kW SRM. Simulations results with modified flux observer and with fast torque response are presented and discussed, along with ...
Prediction of torque and inductance displacement characteristics of asymmetrically slotted variable-reluctance motors using a simplified model for numerical field solution
Ertan, Hulusi Bülent (1999-09-01)
For prediction of static and dynamic performance of doubly-salient motors, it is essential to know their flux linkage-position-excitation characteristics and also the static torque characteristics. At the design stage determination of these characteristics presents difficulties because of highly nonlinear behavior of the magnetic circuit. It is possible to use numerical field solution of the complete motor to obtain this information. This, however, requires expertise on a professional program and may be exp...
