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.

Abstract: A magnetic indicator ring has a set of boundaries between magnetic domains. Some or all of these are to be identified. A reference set of measurements of the angular widths between the boundaries to be identified are measured and recorded. Later a second set of measurements of the widths between those boundaries are made and these widths are matched against the reference set. Matching up widths identifies which of the boundaries are which from the reference set. This enables other data recorded respective to those boundaries to be used. For example the other date may be offsets between the boundaries and the position of a rotor in a switched reluctance motor used to drive the compressor wheel in a supercharger.
