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

What is the purpose of damper bars in a synchronous machine?

Damper windings helps the synchronous motor to start on its own (self starting machine) by providing starting torque. By providing damper windings in the rotor of synchronous motor “Hunting of machine”can be suppressed.

What is damper in vibration?

Vibration dampers are used to absorb vibration emanating from machinery, pedestrian traffic, etc. primarily to reduce the noise associated with such vibration and to procure a more comfortable environment.

How to Calculate Diameter of Damper Bar?

Diameter of Damper Bar calculator uses Diameter of Damper Bar = sqrt((4*Area of Damper Winding)/pi) to calculate the Diameter of Damper Bar, Diameter of damper bar is the distance from one point on the surface of a circle to the other point on the surface of the circle through the centre. The diameter of a damper bar, also known as a damper winding or amortisseur winding, in an electrical machine can be determined based on various factors such as machine design requirements, damping characteristics, and mechanical considerations. Diameter of Damper Bar is denoted by D_d symbol.
