A four stroke single cylinder combustion engine starting system with an electrical machine is operable as both a generator and a motor. The invention also relates to the use of these substances as medicaments for humans and animals. The first secondary windings include an upper gate winding connected to an upper-gate power supply circuit for switching on and off a switching element of an upper arm of the inverter, and the upper gate winding is wound on an outermost side to be separated away from the one of the first secondary windings. The main body forms therein a channel for containing an adhesive dissolving liquid.
