A connecting terminal for a stator which is fitted and fixed in a fitting bore provided in a bobbin included in the stator, includes an external-conductor connecting terminal section fitted and fixed in the fitting bore with one end connected to an external conductor protruding from the fitting bore, a flat plate-shaped connecting plate section connected at one end at right angles to the other end of the external-conductor connecting terminal section and extending outwards in a radial direction of the stator, and a coil connecting terminal section which extends away from the bobbin and which is connected at right angles to the other end of the connecting plate section, so that the coil connecting terminal section can be folded to a position superposed onto the connecting plate section. The coil connecting terminal section is formed into a tubular shape, so that a lead wire extending from the coil can be inserted through the coil connecting terminal section and can be connected to a tip end of the coil connecting terminal section by fusing. With such arrangement, the operation for connecting the coil to the connecting terminal can be easily carried out, whereby the number of steps of the connecting operation can be reduced, and the space for disposition of the connecting terminal can be reduced in size.

Connecting terminal for stator

In the frame of an engine generator are arranged an engine, a generator adjacent to the engine, and a fuel tank disposed above the generator. A muffler of the engine is disposed on a side of the fuel tank, and a heat shield plate is provided in the frame and interposed between the muffler and the fuel tank. Accordingly, the muffler can be disposed in the vicinity of the fuel tank while avoiding an adverse influence of the radiation of heat from the muffler of the engine on the fuel tank, and the degree of freedom in layout of the engine can be increased.

Engine generator

A d-c arc welding apparatus including an engine-driven welder converting the a-c power generated by an engine-driven alternator into d-c power for use as the drive power of the welder, a battery-driven welder using a battery as the drive power of the welder, and a changeover switch for selecting between a high-power mode in which the above-mentioned welding d-c outputs are connected in parallel and fed to the welding apparatus, and a low-power mode in which either of the above-mentioned welding d-c outputs is supplied independently to the welding apparatus.

D-C arc welding apparatus

An engine-driven power generating system comprising a bridge circuit section in which a low-frequency switching elements driven alternately by low-frequency drive signals, and high-frequency switching elements driven by high-frequency drive signals during the ON period of the low-frequency switching elements are connected in a bridge network, and an inverter circuit section having a drive signal supply circuit for supplying low-frequency and high-frequency drive signals are each supplied to the low-frequency and high-frequency switching elements that form a pair; the a-c voltage generated by an engine-driven a-c generator is converted into d-c voltage that is in turn converted into a predetermined level of low-frequency a-c voltage; characterized in that an emergency relay circuit device for protecting the engine-driven power generating system against abnormal operating condition.
