The LR-630 generator is electrically similar to earlier models. The generator features the following major components:

The LR stands for liquid-cooled rectifier bridge; the 6 stands for permanent magnet hybrid, the 30 stands for 130 millimeters outside diameter of the stator laminations. The generator is rated at 150 amperes.

The generator features permanently lubricated bearings and a liquid-cooled rectifier bridge. Service should only include tightening of related components and installation or replacement of the coolant hoses. Otherwise, replace the generator as a complete unit.

The voltage regulator controls the field current of the rotor in order to limit system voltage. The regulator switches the current on and off at a rate of 400 cycles per second in order to perform the following functions:

At high speeds, the on-time may be 10 percent with the off-time at 90 percent. At low speeds, the on-time may be 90 percent and the off time 10 percent.
