Patent

CA 2289331

The invention has the object to improve a handheld portable work tool with an internal combustion engine such that the carburetor heater and the grip heater can be supplied with respectively adjusted electrical energy. By separating the generator windings into individual, electrically separated groups of excitation coils, an adaptation to the respective heating device with an optimal operating point is possible. The electrical separation into individual excitation coils and their selective combination into sets of excitation coils, which in the circumferential direction of the pole wheel are arranged in a row adjacent to one another, has furthermore the effect that a voltage drop caused by field weakness as a result of a load current has only a minimal effect on the other set of excitation coils. The coupling by a common coil resistor of the generator coil is thus eliminated.
