These instructions do not purport to cover all details or variations in equipment nor to provide for every possiblecontingency to be met in connection with installation, operation or maintenance. Should further information be desired orshould particular problems arise which are not covered sufficiently for the purchasers purposes the matter should bereferred to the GE Company.

I. CONSTRUCTION

The PMG stator has a single phase winding in a laminated core. The rotor contains 12 strong permanent mag-nets. The PMG is coated with a fungus and moisture resistant varnish. The PMG is bolted to the end of themain generator shaft, outboard of the diode wheel and exciter.

With reasonable care the PMG will give years of trouble-free service. It is not adversely affected by a deadshort at its terminals for a short time. Prolonged overloads or short circuits can damage the windings.

CAUTION

Do not apply ac or dc voltage to the winding of the PMG that will cause currentto flow through the winding.

II. DESCRIPTION OF OPERATION

The brushless excitation system with a PMG is an independent, reliable device for providing dc excitationcurrent to the main generator. Rotation of the permanent magnet furnishes ac power which is rectified andcontrolled by the voltage regulator for excitation of the exciter field. Alternating current is produced by theexciter and rectified by the diode assembly. The output of the diode assembly is fed directly to the main gener-ator field.

The PMG is self-ventilated by the inherent fan action of the diode wheel. Air is drawn in through the exciterassembly and passes over the PMG.

III. INITIAL INSPECTION AND STORAGE

If not mounted on the main generator, the PMG parts are shipped in a foam sealed container. Desiccant isincluded and unpainted surfaces are rust protected. This provides adequate protection for indoor storage of3 to 6 months. Inspect for shipping damage.

The PMG motor is a strong magnet. It should be covered to keep it from picking up iron filings. Large ironmasses should not touch the rotor as this could demagnetize the rotor.

IV. ASSEMBLY

Follow the instructions and drawings supplied with the exciter.

The PMG stator weight is 32 pounds. The rotor weight is 31 pounds.

After mounting the PMG stator and rotor, measure the PMG air gap (0.0880.083 inches) at 4 positions 90apart. Center the PMG rotor so that the air gaps are whin 5% of the average. Tighten the mounting bolts.

Check to make sure that all bolts are torqued as required. Bend all lockplates and install lock wires to securethe critical bolts.

V. PERIODIC MAINTENANCE

The PMG should be cleaned with the same regularity and tin the same manner as the main generator. All leadwires should be in good condition and tightly fastened. The corrosion resistant coating should not be dam-aged. Any connections removed and replaced should be sprayed with a good quality, air drying insulatingvarnish.

WARNING

Adequate cleaning requires solvent use. Provide adequate ventilation andavoid contact with skin. Use extreme caution with petroleum solvents, astheir fumes are highly flammable.

For best results, apply solvents under pressure using an aspirator or similar device with a clean, dry com-pressed air supply. Less efficient, but acceptable means of applying solvent include self-contained (garden-type) sprayers, vacuum cleaner with spray attachment, portable sprayers and so forth.

Initial cleaning should be done with a slow drying solvent having good oil and dirt cutting properties. Thisshould wash out most of the dirt, oil and soot. Use Stoddard solvent, mineral spirits or alcohol. This shouldbe followed by a quick drying solvent, such as Freon-TF, which finish-cleans and leaves the wheel dry.

VI. INSULATION RESISTANCE

The PMG stator insulation resistance should be over 50 Megohms when tested with a 1,500 volt megger.

A low megger reading can be caused by dirt, moisture, or insulation damage (usually at some terminal).Cleaning and drying is recommended.

VII. LOSS OF EXCITATION

If the PMG is suspected, disconnect the PMG from the regulator and check for winding continuity. The nor-mal resistance of the PMG is 0.1 ohm. If the unit is running the open circuit voltage should be 100 to 150volts ac.

If the problem still cannot be corrected, then thoroughly examine the main generator and control circuitry.At this time contact the nearest Service Office for assistance.
