Abstract
An improved method of starting a switched reluctance motor uses two neighbouring pairs of coils, both energised, to bring the rotor to its initial position. Then one of pairs of coils is turned off and the rotor is attracted by the other pair of coils to give it an initial rotational speed. An intermediate stage uses just one pair of coils of the motor to bring it up to operational speeds, after which the normal cycling of all the coils can be used.
