Alternators

Salient Features :

• Alternators are made in MS Body (10 times better than Aluminum body).
• We use 100% Pure Copper(Insulation H Class) only which prevents from burning.
• We use 100% genuine SKF or NBC bearing only which creates loss of failures in Alternators.

Construction :

• Generators are available in rotating field, self excited and self regulated in Brushless and compounding system.
• The stator frame is of rolled steel with welded feet.
• Rotor core is made up of cold rolled sheets held under pressure on the grounded steel shaft.
• End shields are of cast iron construction.
• Stator is skewed for better waveform.
• Continuous damper winding fitted on poles.

Electrical performance :

• Bridge rectifier.
• Good overload characteristic.
• Can generate electricity in both directions.
• Voltage regulation within +-5% for compounding system and +-1% in Brushless version.
• Voltage adjustment range is +-5% of nominal voltage.
• Epoxy gel coating on windings after varnish for resistance against moisture.
• Good motor starting capability, the compounding system giving 2.5 to 3 times of full load capability for short duration.
• Positive voltages build up from residual magnetism.
• Sustained short circuit current in the order of 3 times of full load current.
• Voltage dips on application on full load 0.8pf on the order of 10% to 15%
