DESIGN AND IMPLEMENTATION OF SWITCHED RELUCTANCE MOTOR

Abstract

In this paper, the switched-reluctance motor uses an electronic position sensor to determine the angle of
the rotor shaft and solid state electronics to switch the stator windings, which also offers the opportunity for dynamic
control of pulse timing and shaping. This differs from the apparently similar induction motor which also has
windings that are energized in a rotating phased sequence, in that the magnetization of the rotor is static (a salient
pole that is made 'North' remains so as the motor rotates) while an induction motor has slip, and rotates at slightly
bellow synchronous speed. This absence of slip makes it possible to know the rotor position exactly, and the motor
can be stepped arbitrarily slowly.The proposed method is implemented on a 100W, 48V, 8/6, 4 phase SRM drive for
validation purposes.
