A method of controlling synchronous running of a plurality of electronically commutated motors ( 22, 24, 26 ), each of which includes a stator having a stator winding ( 40, 42, 44 ), a permanent-magnet rotor ( 28, 30, 32 ), and at least one arrangement ( 34, 36, 38 ), associated with the respective motor, for sensing its rotor position and for generating a rotor position signal (H 1 , H 2 , H 3 ). Also provided is an energization arrangement ( 46 ), to which the stator windings ( 40, 42, 44 ) of the motors are connected. The method includes the steps of detecting occurrence of a predetermined state of the rotor position signals (H 1 , H 2 , H 3 ) and, in response thereto, triggering simultaneously commutation of the currents in all the motors.
