Abstract:
1. A method of commutating an electronically commutated motor ( 20 ), which motor comprises a positive connecting lead ( a stator having at least one winding phase ( a permanent-magnet rotor ( a rotor position sensor ( a full bridge circuit ( two complementary MOSFET transistors (e.g. comprising the steps of: in the context of a predetermined change in the rotor position signal (u while the MOSFET transistor to be switched off is being switched off, monitoring the gate potential of the MOSFET transistor to be switched off by means of a comparator associated with the MOSFET transistor of a bridge arm that is to be switched on; and once that gate potential has reached a value that is characteristic of a switching off of the MOSFET transistor to be switched off, switching ON the MOSFET transistor to be switched on by means of the comparator associated with it.
