Section 1 GENERA T OR FUND AMENT ALS MA GNETISM Magnetism can be used to produce electricity and electricity can be used to produce magnetism. Much about magnetism cannot be explained by our present knowledge. However, there are certain pat- terns of behavior that are known. Application of these behavior patterns has led to the development of gen- [...]

Section 1 GENERA T OR FUND AMENT ALS A SIMPLE A C GENERA T OR Figure 1-4 shows a very simple AC Generator. The generator consists of a rotating magnetic field called a ROTOR and a stationary coil of wire called a STA- TOR. The ROTOR is a permanent magnet which con- sists of a SOUTH magnetic pole and a NORTH mag- netic pole. As the MOTOR turns, its [...]

Section 1 GENERA T OR FUND AMENT ALS NOTE: AC output frequency at 3720 rpm will be about 62-Hertz. The “No-Load” is set slightly high to prevent excessive rpm, frequency and voltage droop under heavy electrical loading. Generator operation may be described briefly as fol- lows: 1. Some “residual” magnetism is normally present in the rotor a[...]

Section 1 GENERA T OR FUND AMENT ALS FIELD BOOST When the engine is cranked during startup, the engine control circuit board Terminals 9, 10, and 11 (Wire 14) are energized with 12 VDC. Connected to a Wire 14 is a resistor (R2) and a diode (D2). Battery current flows through the 20 ohm 12-watt resistor and the field boost diode D2, the voltage is r[...]

Section 2 MAJOR GENERA T OR COMPONENTS RO T OR ASSEMBL Y The Rotor is sometimes called the “revolving field”, since it provides the magnetic field that induces a voltage into the stationary Stator windings. Slip rings on the Rotor shaft allow excitation current from the voltage regulator to be delivered to the Rotor wind- ings. The Rotor is dri[...]

Section 3 INSULA TION RESIST ANCE TESTS EFFECTS OF DIRT AND MOISTURE Moisture and dirt are harmful to the continued good operation of any generator set. If moisture is allowed to remain in contact with the Stator and Rotor windings, some of the moisture will be retained in voids and cracks of the winding insula- tion. This will result in a reduced [...]

Section 4 MEASURING ELECTRICITY METERS Devices used to measure electrical properties are called meters. Meters are available that allow one to measure (a) AC voltage, (b) DC voltage, (c) AC fre- quency, and (d) resistance in ohms. The following apply: • To measure AC voltage, use an AC voltmeter. • To measure DC voltage, use a DC voltmeter. •[...]

Section 4 MEASURING ELECTRICITY MEASURING A C FREQUENCY The generator's AC output frequency is proportional to Rotor speed. Generators equipped with a 2-pole Rotor must operate at 3600 rpm to supply a frequen- cy of 60-Hertz. Correct engine and Rotor speed is maintained by an engine speed governor. For models rated 60-Hertz, the governor is ge[...]

Section 4 MEASURING ELECTRICITY ELECTRICAL UNITS AMPERE: The rate of electron flow in a circuit is represented by the AMPERE. The ampere is the number of electrons flowing past a given point at a given time. One AMPERE is equal to just slightly more than six thou- sand million billion electrons per second. With alternating current (AC), the electro[...]
