FIELD: power engineering.SUBSTANCE: portable electric plant comprises a heat engine and a power generator installed in a body. A working piston and an auxiliary piston connected to each other with a stem form a working chamber of the heat engine and an auxiliary chamber in the body. Cores of the stator winding are made circular, of double-T cross section, circular magnets cover the stem and are arranged at both sides of the cores. During motion of the stem with the piston the circular magnets generate AC in the stator winding. The air compressed by the auxiliary piston in the auxiliary chamber may be used to drive a pneumatic tool.EFFECT: invention makes it possible to increase reliability of operation of a portable electric plant, a power generator and to simplify design of a heat engine.4 cl, 2 dwg |
