The stationary stator is in robust construction and is made from mild steel and carries four poles. Each pole is provided with main and auxiliary field winding. Class "B" Insulation is used throughout. All windings are vacuum impregnated duly baked at proper temperature and coated with gel cot to prevent the ingress of moisture. The end-shields are of cast-iron. The screen projection is provided to protect the armature winding, field winding and other accessories from dust and serves the ventilating facility. Quality ball bearings are used. These are properly greased and have provision of re-lubrication whenever required. The slip-ring are of phosphor bronze and either two, three or four ring assembly are provided for single phase , direct welding and three phase alternators respectively, carbon brushes of ample size are used for continuous running and rated load. The radial bladed fan is used to give equal amount of air in each direction. RAJDOOT alternators are self excited, self regulated type, The alternator field retains high degree of residual magnetism to ensure that the voltage will always build up on starting.
