Özet

In this study, an Outer Rotor Switched Reluctance Motor (OR-SRM) was designed and calculated for electrical vehicle by finite element method (FEM). This motor has very simple geometrical structure. It has no rotor winding, bar, magnet, brush and bracelet. The OR-SRM has outer rotor and it generates high torque because diameter of rotor is enlarged. The OR-SRM which is installed in wheel drive the vehicle directly. It doesn't require gear box. Proposed OR-SRM has a 12 / 8 pole combinations, 3 phases, 5 kW power and 1200 rpm maximum speed. This study presents determination of motor geometrical structure parameters. Power, torque, inductance parameters and magnetic model of the OR-SRM are examined. The OR-SRM is analyzed by Maxwell 3D field simulator. Analysis results are verified by analytical calculations. The motor phase inductance profile, instantaneous torque values are predicted in a variety of rotor positions obtained from simulation results. Approximately 40 Nm of torque are calculated for 5 kW, 1200 rpm speed. Copyright (C) 2011 Praise Worthy Prize S.r.l. - All rights reserved.
