Armature Diameter using Output Equation

Go Armature Diameter = sqrt(Output Power/(Output Coefficient AC*1000*Synchronous Speed*Armature Core Length))

Armature Core Length using Output Equation

Go Armature Core Length = Output Power/(Output Coefficient AC*1000*Armature Diameter^2*Synchronous Speed)

Area of Field Conductor

Go Area of Field Conductor = (Full Load Field MMF*Resistivity*Length of Mean Turn)/Field Coil Voltage

Diameter of Damper Bar

Go Diameter of Damper Bar = sqrt((4*Area of Damper Winding)/pi)

Cross Sectional Area of Damper Winding

Go Cross-Sectional Area of Damper Winding = Area of Damper Winding/Number of Damper Bar

Number of Damper Bars

Go Number of Damper Bar = Pole Arc/(0.8*Slot Pitch)

Length of Damper Bar

Go Length of Damper Bar = 1.1*Armature Core Length

Cross Sectional Area of Damper Winding Formula

Cross-Sectional Area of Damper Winding = Area of Damper Winding/Number of Damper Bar
σ_d = A_d/n_d

Where damper winding is placed?

Damper winding is placed in the slots at the surface of pole shoes in salient pole machines and in in non-salient pole machine it is placed in the same slots with magnetizing windings.

Which material is used for damper windings?

They are made of copper as the current also flows through them.Damper winding are mechanical windings which also reduce the hunting.
