Electronically commutated single-phase motor

摘要

The present invention refers to an electronically commutated single phase motor comprising a rotor ( 2; 202; 302 ) and a stator ( 3; 203; 303 ) with an asymmetrical wound yoke ( 4; 204; 304 ) and comprising at least a stator phase ( 5; 205; 305 ) energized via an electronic commutation circuit in accordance with a driving signal generated by sensor means ( 8; 208; 308 ) for detecting the angular position of said rotor ( 2; 202; 302 ); said sensor means ( 8; 208; 308 ) comprise at least an inductive coil ( 9; 209; 219; 309 ) that is coupled magnetically to said rotor ( 2; 202; 302 ) and is arranged at substantially 90 electrical degrees with respect to said stator phase ( 5; 205; 305 ); the inductive coil ( 9; 209; 219; 309 ) and the stator phase ( 5; 205; 305 ) are arranged adjacent to each other and are wound round axes that are substantially parallel to each other.
