Abstract
A method for starting up a rotor of a single-phase claw-pole motor, wherein the claw-pole motor comprises a permanently excited rotor which executes a movement in a running direction in nominal operation, an electronically commutated stator and a Hall sensor for determining the relative rotor position, wherein the method comprises the steps of generating a pulse for moving the rotor in the direction opposite to the running direction by energizing a stator winding on the basis of an inverted Hall sensor signal; and starting up the rotor for movement in the running direction by energizing a stator winding on the basis of a Hall sensor signal.
