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

Length of Damper Bar Formula

Length of Damper Bar = 1.1*Armature Core Length
L_d = 1.1*L_a

What is the purpose of damper winding in alternator?

Therefore, damper winding provides starting torque necessary for starting the synchronous motor. It also prevents hunting of synchronous motor, that is it reduces oscillations of the rotor when the motor deviates from synchronism.

Why is it called damper winding?

Synchronous motors

usually referred to as a damper winding because of its additional property of damping out any oscillation that might be caused by sudden changes in the load on the rotor when in synchronism.

How to Calculate Length of Damper Bar?
