This work aimed to develop a parameterized, two-dimensional field model of a switched reluctance motor (SRM). The main task of the developed model was to calculate the value of the electromagnetic torque for various positions of the rotor. Based on these calculations, the characteristics of the electromagnetic torque were determined depending on the position of the rotor angle φ for the current function I (T = f (φ, I)). Using the model, it was possible to additionally observe the phenomena occurring in the motor winding, e.g., distributions, isolines of magnetic potential, induction, and to calculate the values of the temperature. The parameterized structural elements that made up the entire model can be freely changed and, thus, the results for various structures can be obtained. Thanks to this, it was possible to evaluate and compare motor of different designs. To validate the model, measurements were conducted on real-scale reluctance motors, and families of electromagnetic torque characteristics were obtained for various design cases. The results received from the tested motors were juxtaposed with simulation results procured via the model. Based on this comparison, it was possible to determine the accuracy of the model’s operation.

Radial Forces

The shape of rotor poles has a significant influence on the performance of electromagnetic torques and radial forces, because the air-gap flux density is depent on the stator and rotor areas and surfaces. Serveral articles have studied influences of the stator/rotor designs on radial forces and electromagnetic torque waveforms as well. Moreover, the electromangetic characteristics of switched reluctance motors are also defined by tapped-shoe-skewing of the stator and rotor poles with the inner holes. However, the total solution designs of the tapped-shoe rotor with diferent tapped angles have not yet implemented by those papers so far. For that, in this paper, the tapped shoe rotor pole design is proposed by different angles for the high speed switched reluctance motor of 30 kW and 18000 rpm.

Self Tuning

This study adopts the fuzzy control theory to design a self-tuning fuzzy controller (STFC), which allows adjustment to overcome the controller design difficulty caused by switched reluctance motor (SRM) nonlinearity. Based on the torque sharing function (TSF), the proposed STFC was implanted into an SRM direct torque control (DTC) drive system to develop a system with superior speed and electromagnetic torque dynamic responses. In addition, the control strategy possessed excellent electromagnetic torque response, and effectively improved the dynamic response of the system. Keywords: fuzzy control theory, switched reluctance motor (SRM), torque sharing strategy.

Background: Switched reluctance motor (SRM) is a promising type of electromechanical energy converter. It is used in both motor and generator modes. SRM can be used not only in mechanisms with rotational motion, but also as linear motors, including maglev transport systems. A lot of publications are devoted to SRM design issues. In development of this direction, further improvement of the SRM design process is proposed using the optimization method of forming the geometrical dimensions of the tooth zone. Aim: Reducing of electromagnetic torque ripple SRM by optimizing the geometrical dimensions of the tooth zone. Materials and Methods: To simulate magnetic fields, the FEMM 4.2 program was used. The implementation of the optimization algorithm and the processing of the results of field calculations, was carried out in the MATLAB program. The Monte Carlo optimization methods (they rely on random sampling) was taken as the basis for developing the optimization algorithm, and its improvement was achieved using mathematical methods based on probability theory. Results: As a result of the optimization calculations, the tooth zone geometry was obtained, which provides a reduction in the pulsation of the SRM electromagnetic torque ripple from 122% to 40%. Conclusion: The studies presented in the paper indicate the effectiveness of using the optimization algorithm in designing SRM, as well as the feasibility of removing restrictions on the shape of the tooth SRM and the use of a curved tooth shape, which is determined in the process of solving the optimization problem by a determined criterion.
