In this paper, a novel magnetic parameter design methodology is proposed for switched reluctance motors (SRMs). Based on the nonlinear characteristic of flux linkage, the design equations of structural and winding parameters are derived. The benefit is that there are no meaningless empirical design coefficients in the proposed design methodology. Three …

Permanent magnet motors are very efficient, but only in a very narrow rpm band, and quickly lose their efficiency in the varying speeds of normal driving. Shunt and compound motors are more expensive to build and have poorer acceleration than series motors. For these reasons, the brushed series DC motor is the motor of choice for DC systems.
This paper is committed to show a well-ordered system used to design a permanent magnet synchronous generator (PMSG).
