Design Trend of a Novel Three-Phase Five Layers Switched Reluctance Motor for High Torque Applications

This paper presents a novel three-phase five layers Switched Reluctance Motor (FLSRM) with its design trend and numerical verification. The proposed motor has five 4 by 4 magnetically independent layers. By turning on each two layers and repeating the excitation schematic, the motor will produce torque. The presented FLSRM is then compared with a conventional 6 by 4 SRM with the same volume and area. The motor is designed in such a way that two layers are turned 072 each time, which produces more torque and also decreases the torque ripple in compare with the 6/4 SRM. The FLSRM can works in higher speed, since independent layer there is no isolation problem which exists in the conventional 6/4 SRM On the other hand, there is more area for coil wrapping in FLSRM which means the motor can produce more torque and also the motor cooling can be done easily. The design verification is carried out by the 3-D magneto-static Finite Element Analysis to analysis the motor parameters. Copyright (C) 2012 Praise Worthy Prize S.r.l. - All rights reserved.
