Quantitative Comparison and Analysis of Magnetless Machines With Reluctance Topologies

This paper quantitatively compares three advanced magnetless machines, namely the switched reluctance (SR) machine, double-stator SR (DS-SR) machine and DS multitoothed SR (DS-MSR) machine. The DS-SR machine is particularly favorable for low-torque highspeed operation while the DS-MSR machine is des...

Description
Summary:This paper quantitatively compares three advanced magnetless machines, namely the switched reluctance (SR) machine, double-stator SR (DS-SR) machine and DS multitoothed SR (DS-MSR) machine. The DS-SR machine is particularly favorable for low-torque highspeed operation while the DS-MSR machine is desirable for high-torque low-speed operation. Because of more effective power transfer by using two stators, the two DS machines achieve better performances than the single-stator counterpart. All machine performances are analyzed by using the time-stepping finite element method.
