Gen-Set Theory of Operation
Generators are mechanical devices that convert mechanical energy into electrical energy. In every generator that Kohler produces, the mechanical power is provided by either an air or a liquid cooled internal combustion engine (ICE). These engines vary in size and power output, but the theory of operation behind them is identical. This means that the small internal combustion engine on a lawn-mover operates in roughly the same way as the large multi-cylinder engines in our RCL line of units.
The mechanical force provided by the ICE turns the power generation unit, which is called the alternator. The alternator consists of a few basic components including the stator, rotor, brushes, and alternator housing. The stator is the stationary component that is fixed to the alternator housing. The stator consists of layers of laminated steel plates wrapped by coils of copper wire. This is where the power is generated by the unit! The next component is the rotor assembly. The rotor is attached to the ICE, and as a result, rotates at engine speed. The rotor contains a primary shaft, many layers of steel plates, and is also wrapped in coils of copper wire, which become magnetized when 12-volts are applied to each end of the coil. Once magnetized, the rotor spins inside of the stator. As this occurs, the magnetic lines of flux pass through the coils of wire in the stator, which cause voltage to be induced in the stator through a phenomenon known as electromagnetic induction.
