ST/STC generator is composed of stator, rotor, end cover, frame, bearing and other components. The stator consists of a frame, a stator core, wire winding, and other structural parts fixing these parts;  The rotor is composed of rotor iron core with magnetic choke, magnetic pole winding, slip ring, fan and rotating shaft, etc.  By bearing and end cover of generator stator and rotor connected together, the pay of the stator winding through the carbon brush and collector ring contact transmission to the pole, a magnetic field by electromagnetic induction, because the rotor is engine driving rotating in the stator, do the exercise cutting lines, thus induced potential, through terminal lead, in the circuit, the electric current is produced.  

The generators we produce now are mainly used in conjunction with internal combustion engines.  Internal combustion engine is a machine convert chemical energy into mechanical energy, its conversion process is actually the process of the work cycle, is simply through the burning of fuel in the cylinder, kinetic energy, driving the piston reciprocating motion inside the engine cylinder, effect on the piston thrust through connecting rod into promoting the power of the crankshaft, so as to drive the crankshaft,  The generator and crankshaft coaxial installation, you can use the rotation of the diesel engine to drive the rotor of the generator, the use of “electromagnetic induction” principle, the generator will generate induction potential, through the wiring terminal leads, connected in the loop, then produced the current.
