A machine, in particular a washing machine having a basket (53), a motor comprising a rotor (11;21) and a stator (15;25), said rotor (11;21) and stator (15;25) comprising magnetic field-generating elements arranged according to respective basic configurations susceptible of generating a respective rotor and stator magnetic field interacting to induce on said stator (15;25) an electromotive force (È) having a temporal behaviour that varies periodically, said motor (10;20) being associated with said basket (53) through said rotor (11;21),
said basket (53) being susceptible of assuming at least one predetermined angular position (¸ p ), said machine being associated with logic control means (55) to detect said predetermined angular position (¸ p ). Said magnetic field-generating elements comprise a respective element (24,27) susceptible of perturbing said respective basic configurations and to determine a corresponding deformation (L) in said periodic temporal behaviour of the induced electromotive force (È),
said logic control means (55) are configured to identify said deformation (L) and employ said deformation (L) as reference position for the detection of the angular position (¸ p ). |
