Abstract
Disclosed are a method and system for measuring a flux-switching electric motor rotor angle on the basis of linear Hall. The method comprises: firstly, selecting four linear Hall sensors and respectively mounting same in four slots of a stator; a first linear Hall sensor is mounted in any slot of the stator, and a second linear Hall sensor is spaced apart from the first linear Hall sensor by Nslots in a unified direction; Nis an even number, and N≠ks/(2); a third linear Hall sensor is spaced apart from the first linear Hall sensor by Nslots; Nis an odd number, and N=(2−1)s/(2); and a fourth linear Hall sensor is spaced apart from the second linear Hall sensor by Nslots; and then calculating an electric motor rotor angle according to voltage signals of the four linear Hall sensors.
