Engine starting and charging device

Image Number 2 for United States Patent #4894553.

A field coil is divided into the plural number, and each of these field coils is connected in parallel in relation to a battery at the time of engine starting, and in series during the generation of the electric current after engine starting, so that sufficient field electromotive force can be maintained in the event of a battery voltage drop during engine starting, and also a necessary, sufficient field electromotive force can be produced with little current at the time of voltage recovery during generator operation. Consequently, the amount of copper to be used for the field coils and a winding space can be decreased; therefore the present invention is effective to provide a light-weight, small and unexpensive engine starting and charging device.
