Development of a simple analog controller for switched reluctance motor

This paper presents a simple analog control scheme for speed control of switched reluctance motor (SRM). It is designed to operate with minimum number of switching devices. It makes use of rotor position signals, speed signal, and current signals in the closed loop feedback control. The proposed scheme is useful for low power rating applications. Use of off-the-shelf electronic components makes the controller simple, reliable, and economical. The test results are presented for 4 kW, 4-phase, 1500 rpm motor which has 8 poles on the stator and 6 poles on the rotor.
