A New Design Approach for Torque Improvement and Torque Ripple Reduction in a Switched Reluctance Motor
Journal Title: IOSR Journals (IOSR Journal of Electrical and Electronics Engineering) - Year 2017, Vol 12, Issue 5
Abstract
High torque ripple and high acoustic noise are the major disadvantages of Switched Reluctance Motor (SRM). SRM has valuable features like low cost, reduced maintenance requirements, fault tolerance, high efficiency, rugged behavior and large torque output over a very wide speed range the researcher giving more concentration to this device, there are several publications which gives full or partial solution to the problems of SRM. This paper proposes a simple new structured stator and rotor design for SRM to increase the torque and reduce the torque ripple considerably. The proposed 8X8 motor Consists of six layered magnetically independent stator and rotor sets .Each layer works exactly in a complementary way and helps to another layer in an accurate method to give a suitable torque output. Based on special switching method at a time one layer produces torque and the remaining layers doesn’t produces torque and it continues periodically with six layers which results in high torque and less ripple, low noise and vibration. This proposed method with six layered rotor and stator with special switching method works complementary to each other and hence produces high torque with less torque ripple and noise.
