Abstract

Switched reluctance motors have been widely used in industry in recent years. One of its most important advantages is its high-power density and its independence from rare magnet poles. In this study, a new motor design is proposed to increase the average and maximum torque values of a 2.2 kW switched reluctance motor. In the proposed design, slits are opened in the poles in the rotor core. Magnetic field and potential vector distributions, inductance, current and torque values are obtained for reference and slitted motor models. Analyzes were made using the Maxwell 2-D program. According to the results, it is determined that the proposed motor design for the same size and power values provides an improvement in the average and maximum torque values.
