methods of cooling

Answer Posted / m paul prasad

Alternators can be classified as below
Based on rotor
1. Salient pole type
2. Smooth cylindrical type
Based on output power
1. Single Phase
2. Three Phase
Based on the working principle
1. Revolving armature type
2. Revolving field type
Based on the speed on rotation
1. Turbo alternator
2. Low speed alternator
Based on coiling
1. Air cooling
2. Hydrogen cooling
