Abstract

The utility model discloses a single-phase small-sized gasoline generating set. A gasoline engine of a power mechanism of the gasoline generating set is directly coupled with the rotor of an electric motor assembly through a crankshaft to drive the rotor to rotate. The outside of the rotor is a stator core with a winding. The power mechanism and the electric motor assembly are fixed at the bottom part of a generator stander of a stander assembly. An automatic voltage regulator (AVR) with voltage adjustment function, a wire passing ring and a carbon brush are arranged on a stator rear bracket assembly. The wire passing ring and the AVR are arranged above the rear part of the rotor. The generating set can realizes the purpose of outputting stable 6.5 kW rated power only by changing the power of the prior 5.5 kW single-phase small-sized gasoline generating set into a single-cylinder four-stroke 190F gasoline engine with a piston with the diameter Phi of 90 mm plus or minus 0.2 mm and the 66 piston travel on the basis of no changing the basic structure of the prior small-sized gasoline generating set. The crankshaft is directly coupled with the rotor, so the added losses produced due to the connection by a coupler of the traditional small-sized gasoline generating set are reduced.
