The invention relates to a starting device for an electric power generator as a unit consisting of an internal combustion engine and a generator, in which the rotor (17) of the generator is connected to the crankshaft (1) of the internal combustion engine in a rotationally fixed manner. Said device comprises at least one starting coil arranged on either the rotor (17) or the stator (11), at least one starting magnet which is arranged on the other rotor or stator (17 or 11) and co-operates with a magnetic field of the starting coil through which a current passes, at least one fixed coil current switch (24) having two switching states for connecting the starting coil to a current source or separating the starting coil from said current source, and at least one switch actuating means which is arranged on the rotor in a rotationally fixed manner, co-operates with the coil current switch, and is used to switch the coil current switch into one of the two switching states according to the angular position of the rotor.

The invention miniaturizes a four-cycle engine wherein camshaft driving means is provided on a crankshaft. [Solving Means] A sprocket wheel 59 for driving a camshaft is mounted on a crankshaft 12 which projects from a crank chamber 9, and a starter/generator apparatus is provided on the outer side with respect to the sprocket wheel 59. A governor 54 including a governor weight 55 which operates with a centrifugal force is provided on the side of an inner rotor 15 adjacent the sprocket wheel 59 while a brush holder 41 including brushes 44 is provided on the outer side of the inner rotor 15. In order to bring the brushes 44 into and out of contact with commutator pieces 53 in response to a movement of the governor weight 55, the governor 54 and the brush holder 41 are connected to each other by a connection pin 45. By the construction described, the extent over which the starter/generator apparatus projects to the outer side can be reduced.

A DC electric motor system includes a rotor portion having a commutator and a coil winding mounted radially about a shaft, and a stator portion including two rows of spaced permanent magnets about either side of the rotor coil winding. Pick-up coils are mounted about the circumference of the electric motor to pick up energy produced by the change in magnetic flux about the edges of the rotor coil winding. The pick-up coils transfer the collected energy as current for use in charging a battery within an electric vehicle, or the like.
