Switched Reluctance Motors (SRM) have inherent advantages such as simple structure with non winding construction in rotor side, fail safe because of its characteristic which has a high tolerances, robustness, low cost with no permanent magnet in the structure, and possible operation in high temperatures or in intense temperature variations. The torque production in switched reluctance motor com...

Permanent magnet synchronous motors (PMSM) are known for their type whose magnets located on the rotor surface and this motor type, which is called mounted (SPM), generates torque due to rotor. Based equations, since there only q axis current value of magnetic flux linkage, d kept at 0 maximized controlled, I_d = control technique. However, reluctance generated in interior permanent (IPM) induc...

By using the energy dissipation theory and the property of the switched reluctance motor, this paper presents a nonlinear controller for the planar switched reluctance motors (PSRM). Based on the fact that the electrical time constant is much smaller than the mechanical time constant, the whole PSRM driving system is treated as a two-time-scale system and can be decomposed into two subsystems (...

The design and analysis of synchronous reluctance motor (SynRM) with a distributed type winding is an alternative to replace the permanent magnet motors (PMSM), which commonly used in electric vehicle applications. use SynRM eliminates need for magnets (PMs), reducing dependence on rare earth materials potentially lowering costs. In this paper, there are two approaches: new approach step-skewin...

This paper proposes a novel hybrid-type permanent magnet motor (HPMM) that simultaneously applies ferrite-PM (Fe-PM) to reduce the amount of NdFeB (Nd-PM) used in electric vehicle traction motors. Conventional HPMM can be divided into parallel type (P-HPMM) and series (S-HPMM). P-HPMM is advantageous for PM torque improvement because it obtain high flux linkage, but there problem Fe-PM demagnet...

In this paper, we present a novel technique to estimate the position of the rotor of a switched reluctance motor by observing the characteristics of the vibration of the stator during the motor operation. This removes the need of the shaft position sensor which is known for its unreliability and problems associated with its application. Vibration in switched reluctance motors is generated mainl...
