dc machine construction


construction and types of synchronous machine electrical

the field winding or dc winding are concentrically wound on the salient pole rotor. this type is only suitable for low speed machine. it is not favorable for high speed machine as due to high centrifugal force on the salient pole the pole faces may damage. the basic construction of rotor of synchronous machine
