Rotor Assembly

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 driven by the engine at a constant speed through a pulley and belt arrangement.

All generator models in this manual utilize a 2-pole Rotor, i.e., one having a single north and a single south pole. This type of Rotor must be driven at 3600 rpm for a 60 Hertz AC output, or at 3000 rpm for a 50 Hertz output.

Slip rings may be cleaned. If dull or tarnished, clean them with fine sandpaper (a 400 grit wet sandpaper is recom- mended). DO NOT USE ANY MATERIAL CONTAINING METALLIC GRIT TO CLEAN SLIP RINGS.

Stator Assembly

The Stator is “sandwiched” between the upper and lower bearing carriers and retained in that position by four Stator studs. A total of eight (8) leads are brought out of the Stator as follows:

1.Four (4) Stator power winding output leads (Wires No. 11, 22, 33 and 44). These leads deliver power to connected electrical loads.

2.Stator power winding “sensing” leads (11S and 22S). These leads deliver an “actual voltage sig- nal to the electronic Voltage Regulator.

3.Two excitation winding output leads (No. 2 and 6). These leads deliver unregulated excitation current to the voltage regulator.
