Influence of Poles Embrace on In-Wheel Switched Reluctance Motor Design

2018 IEEE 18th International Power Electronics and Motion Control Conference (PEMC), 2018

There is very little work about the influence of the poles embrace on the motor design in the literature. This topic has not also been studied for IW-SRM yet. Therefore, this is a novel work and it is researched in this paper. Firstly, 3D numerical model of IW-SRM is built by using Ansys Maxwell Software Package. Then, IW-SRM is analyzed and output torque of the IW-SRM is calculated. The analysis of IW-SRM is realized for different rotor and stator pole embraces and the results of the output torque of IW-SRM taken for various rotor and stator pole embraces are compared with each other. As seen from the results, when the value of rotor pole embrace increases, the output torque of IW-SRM reduces. As a result in this study, the effects of different poles embrace are examined on the output torque of IW-SRM. Thus, proper pole embraces can be selected for optimum motor design.

Investigation of End Effects in Linear Induction Motors by Using the Finite-Element Method

In linear motors, however, either the rotor or the stator has a finite length, and end effects occur because of the part having finite length entering or exiting the magnetic field. End effects occur as magnetic waves having attenuation, and play a major role in the performance of linear induction motors (LIMs), especially at high speeds. As the speed increases, efficiency decreases because of longitudinal end effects. This decrease in efficiency has a braking effect. In high-speed maglev devices, such as trains, the efficiency and performance of the LIMs become very important. We report on our investigation of end effects by the finite-element method.

Optimization of Permanent Magnet Synchronous Motor Design by Using PSO

Since there is no winding in the rotor of PMSMs, the efficiency of the motor is high. However, the windings in the stator cause the copper losses reducing the efficiency of the PMSM and creating heating problems. Therefore, the aim of this study is to decrease the copper losses of the PMSM and solve the heating problem. For this reason, the parameters of the winding structure are optimized by using PSO. Because the production stage of the PMSM is already completed, its geometric structure can not be changed. Only windings are optimized in this paper. Design equations of the PMSM and certain parameters are entered into MATLAB Simulation and the simulation is run by PSO. After the optimization results, electromagnetic analysis of the PMSM is realized by using ANSYS Maxwell 2D. Finally, the winding structure of the renewed motor is tested by experimental setup and the results are validated by the simulation results.

CMV causes negative effects on both electric engine and its driver whereas switching operation occurs in power devices. In addition switching frequency and its multiples in CMV cause electromagnetic and aqustic noises. In this paper a novel Fixed-Frequency chaotic switched sinusoidal pulse width modulation (FFCS-SPWM) is proposed. The cruial point in proposed FFCS-SPWM method is to obtained a new carrier wave by summation of carrier wave and its inverse form. In FFCS-SPWM method extra switching loses were reduced due to constant switching frequency. This method also applied to permanent magnet synchronous motor (PMSM) vector control system. The reduction of electromagnetic interference (EMI), aqustic noises and dv/dt stress effects that occur in CMV is simulated by proposed method. Moreover SPWM combined with chaoticfrequency chaotic switched (CFCS) is proposed to reduce the differential mode voltage (DMV) which occurs due to voltage between lines. Finally in this method switching frequency change chaotically and also in this paper it shown that, CFCS-SPWM provides to reduce EMI, aqustic noises which are caused by CMV and DMV.

However, they cause mass and cost to increase and also efficiency to decrease due to mechanical losses. The aim of this study is to design a direct drive motor (outer rotor switched reluctance motor (OR-SRM)) without reducer resulting in enhanced efficiency for electric vehicle (EV). To estimate dimension and electrical parameters of OR-SRM, mathematical equations are originally derived from its geometry. Considering the constraints of package size and outer diameter, all the dimension parameters of the motor are optimized via multi-objective genetic algorithm (MOGA) to get the desired efficiency and torque. In order to validate the results in the proposed approach, OR-SRM is modeled by Maxwell 3D using optimized dimension parameters. In-wheel OR-SRM with 18/12 poles (30 kW) is manufactured to employ it in an EV. Theoretical results are compared to experimental results. It can be concluded that the results are satisfactory.
