Abstract: In switched reluctance motors magnetic field is produced by only one member, i.e. either stator or rotor. The rotor tends to move to minimum reluctance position for the flux of this magnetic field. Minimum reluctance is achieved when iron comes into contact with the magnet. By sensing the rotor position of SRM is used to switch on and switch off phase windings. In SRM inductance of phase winding varies with rotor position. For a unidirectional torque, current must be present in the coil only when the rate of change of coil inductance with rotor position is positive. Two rotor laminations are kept on the unused portion of shaft to sense the rotor position by using opto sensors as gap detectors. When rotor rotates and comes under influence of gap detectors and generates a pulse. Apparently three pulses generate in every rotation. These pulses act as input to the Arduino mega 2560. These outputs act as triggers for six gates in converter circuit. Converter circuit is connected to SRM. Once supply is applied, current flows through the winding and speed can be measured.
