Patent

CA 2549163

An apparatus and method for providing improved sensorless control of permanent magnet motors is described. Induced electricity from at least one winding set is used to determine rotor position and provide feedback to a commutation circuit driving at least another winding set isolated from the first.

L'invention concerne un appareil et un procédé permettant d'obtenir une commande sans capteur améliorée de moteurs à aimants permanents. L'électricité induite d'au moins un ensemble de bobinages est utilisée pour déterminer une position de rotor et permettre une rétroaction avec un circuit de commutation entraînant au moins un autre ensemble de bobinages isolé du premier.
