Detailed Information of Starlight TFW Series Alternators

Starlight TFW Series AC Generators are of unique design, advanced construction, excellent performances, reliable operation, easy use, small volume and light weight.

Features:

1. TFW series generator are manufactured in accordance with NAME ODP type. It consists of main generator, AC brushless exciter, rotating rectifiers, AVR, conduit box, etc.

2. Class H or Class F insulation system.

3. The frame is made by steel plate. The design of stator lamination is unique. If necessary, 12 1eadwires may be supplied.

4. Main rotor apply the single piece 4-pole salient lamination, coupled with die cast or welding damping winding, field winding to form a unique rotor construction. The field winding is layer wound with thermos setting epoxy for high mechanical and electrical integrity.

Performance:

1. TFW series generator may be operated continuously at rated load under following Conditions:

a. Ambient. Air temperature ≤40°C,well ventilation, marine use, ≤45°C

b. Elevation.≤1,000 m over sea level

2. Electrical performances.

a. Steady voltage regulation≤1.0%

b.Transient voltage regulation≤+20%, -15%

c. Adjustable voltage range 95-105%Un

d. Waveform distortion at no-load,≤ 5%(line voltage.

UP. Storage.

In the event that the generator is not to be installed on its prime mover immediately, it is recommended that the unit be stored in a cleaned, dry area which is not subject to rapid changes in temperature and humidity.

In the event of long term storage, the generator should be tested cleaned and dried as required, before being put into service. See the maintenance section of this manual for further information.

IV. Installation and adjustment.

1. Generator must be mounted at the clean, dry and well ventilation place. The prime mover and generator should be installed on a public frame, never put them on the cement floor, and ensure the public frame under formed.

2. Single bearing generators.

Single bearing units are provided a SAE flywheel housing adapter and flexible drive discs to match the engine. Close tolerances are maintained in the manufacture of the generator to promote ease to alignment.

Special steel drive discs are bolted the shaft. In some case spacer are used to achieve the proper "XG" dimension. Holes are provided in the periphery of the coupling discs which correspond to tapped holes in the engine flywheel. The outside diameter of the drive discs fit in a rabbet in the flywheel so that concentricity is assured.

CAUTION: Grade 8.8 place to the flywheel. Do not use split type lock washers, they will cause stress risers, and may result in disc failure.

The SAE flywheel housing adapter and the engine flywheel housing are designed to match each other, with no further alignment necessary.

Shims may be necessary under the generator feet to insure a solid mounting. Do not force the feet to an uneven mounting surface, serious problems could result.

After, the generator has been assembled to the engine, check for end-play of the assembled set. Using a suitable lever, force the engine flywheel forward so that the crankshaft is pressed against its thrust bearing. When force is removed, the engine crankshaft should remain in position. Apply force in the opposite direction forcing the crankshaft towards the generator, and observe if the crankshaft remains in this position after force has been removed. Refer to the engine manual for proper or recommended end-play. If the crankshaft springs away in either direction after force has been removed, it is an indication that the generator shaft is not moving freely, and normal life of the thrust bearing could be impaired. 

Probable course of this problem are:

a. Improper "XG" dimension of either the generator or the engine flywheel, or both. Generator bearing may be bottoming out in its bearing bracket,

b. Misalignment:

a) Improper seating of generator drive discs in the engine flywheel.

b) Improper mating of the generator frame to the engine flywheel housing.

c) Set sub-base is not true. Generator and or engine feet require shims. See mounting instructions.

3. Two bearing generators.

If generator couples with engine by flange rabbet, it is easy to mount. If it coupled by other way, should pay more attention to installation, it may be necessary to shim the generator feel for proper support and alignment. Aligning the generator and engine as accurately as possible will reduce vibration, increase bearing life, and minimize coupling wear.

Our company can provide multiple brand of alternator, such as original Stamford alternator, Siemens generator, Marathon generator and Engga generator, etc.
