Alternator 7N-9720 Alternator Gp (35 amperes), 9G-9538 Alternator Gp (50 amperes) and 100-5046 Alternator Gp (50 amperes)The N3 series alternator is a brushless, electromechanical component that converts mechanical energy into electrical energy. The alternator charges the battery. The alternator also supplies power for the machine's electrical systems during engine operation.The alternator has a full-wave rectified output that is three-phase. There are two different output versions that are rated at 35 and 50 amperes. The alternator is divided into a front frame and an end frame. The following stationary parts are located inside the two frames: stator, field winding, rectifier and regulator. Stationary parts are bolted to the frames. The rotor is the only moving part in the alternator. The rotor is mounted by ball bearings or by roller bearings. A belt (not shown) provides the mechanical energy for the alternator. The belt is attached to the shaft of the rotor. The belt is used to turn the rotor which also rotates the fan. Air is drawn through baffles in the rear cover. Air exits from the front frame behind the fan.
