  5. Main Alternator Detail
    1. Design: revolving field, brushless, single bearing, 4 pole, dripproof construction; superior mechanical and thermal design achieved through use of the best available materials
    2. Stator: skewed stators and two-thirds pitch windings result in minimum field heating and voltage harmonics; laminations of low loss, insulated, electrical grade steel to maximize efficiency; double dipped in thermosetting, moisture, oil and acid resisting varnish
    3. Radio interference: alternator and voltage regulator meet the provisions of BS.800 and VDE class G and N
    4. Bearing: the rotor is supported by a prelubricated, maintenance free ball bearing
    5. Cooling: direct drive centrifugal blower
    6. Rotor: direct coupled to engine with flexible drive discs; complete amortisseur (damper) windings ensure minimum voltage deviations and heating effects under unbalanced loads; dynamically balanced rotor assembly; impregnated with 100% thermosetting resins
    7. Excitation: the brushless exciter armature feeds the main alternator field winding through a shaft mounted three-phase full-wave silicon diode rectifiers; the semi-conductor surge suppressor protects the diodes against transient overvoltages induced by load surges; the automatic voltage regulator provides variable excitation to assist the engine during transient load conditions
    8. PMG: permanent magnet generator provides constant power for the voltage regulator and provides immunity to SCR tracking
    9. Insulation: the insulation system is class H per NEMA MG1-1.65 and BS2757 definition
