An Analytical Approach for the Calculation of Flux-Linkage Including End-Effect for SR Motors

The accuracy of flux linkage-current-position curves has vital importance for designing SR motors. Analytical prediction of these curves is very difficult and as shown in this paper 2D approach leads to erroneous prediction of the flux linkage curves and hence significant errors in performance prediction of SR motors. This paper makes an important contribution to the design process by developing an approach for the analytical calculation of flux linkage-current-position curves including the end effect. As shown here, using flux-linkage curves predicted with this method leads to accurate prediction of motor performance


An analytical approach for determination of optimal stator/rotor saliency number of a swıtched reluctance motor
Kılınç, Cem Erkan; Bostancı, Emine; Department of Electrical and Electronics Engineering (2020)
The purpose of this study is to seek the optimal stator and rotor saliency number of a switched reluctance motor (SRM) for hybrid electrical vehicle (HEV) applications. For this purpose, first a previously developed SRM analysis software is investigated to identify possible errors in implementation of both the theory and the coding. Performance prediction method is based on the use of normalized force and permeance data produced via numerical field solution, and a polynomial based interpolation is introduce...
Evaluation of a 6 pole axial flux PM motor for Control Moment Gyroscope Application
Zeinali, Raza; Ertan, Hulusi Bülent (2015-09-04)
In a previous study a compact Control Moment Gyroscope (GMC) design, based on a 6-pole, axial flux (AF) motor was presented. The GMC design in that proposal was based on analytical expressions and naturally 3-D structure of the AF motor could not be fully taken into account. In this paper the designed motor is simulated using 3-D FEM solutions. The parameters of the design such as electric loading and current loading as well as the performance of the design such as phase current and the torque produced at 1...
Performance Calculation of SR Motors for Optimum Design and a Washing Machine Application
Ertan, Hulusi Bülent (2008-09-09)
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, ...
Design optimization of variable frequency driven three-phase induction motors
Ertan, B; Leblebicioğlu, Mehmet Kemal; Simsir, B; Hamarat, S; Cekic, A; Pirgaip, M (1998-01-01)
An approach to optimize the design of three-phase induction motors for a wide speed range drive is considered. Two operating points in the speed range are taken into consideration. The problem is handled as a constrained optimization problem. An accurate model for the motor in terms of its dimensions has been developed which predicts the motor performance based on about 60 parameters of motor geometry.
Design of a GaN Based Integrated Modular Motor Drive
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...
