Design, analysis and controlling of a novel 4 by 4 multilayer SRM

In this paper a Multilayer Switched Reluctance Motor (MSRM) is introduced, simulated and controlled. The presented MSRM which has five 4 by 4 magnetically independent layers produces more torque with less torque ripple rather than custom SRMs. The motor is rotated by exciting each layer and repeating the algorithm. Since independent layers, there is no isolation problem in the presented MSRM. The motor cooling can also be done easily. On the other hand, there is more area for coil wrapping in the presented motor which means the motor can generate more torque. The paper presents the design and simulation of the MSRM and also the control algorithm. Different parameters of the motor are obtained by 3-D magnetostatic analysis by Finite Element Method (FEM). The motor is then constructed and tested in laboratory by an asymmetric bridge converter and its characteristics are determined.
