For transforming rotating torque into electric
power, they almost consist of cylindrical rotor with field
they almost consist of cylindrical rotor with field
winding and cylindrical stater with armature winding.
The output power p is obtained as p ¼ k0D2lN, where k0
is called output coefficient, D is a diameter of air-gap
between rotor and stater, l is length of air-gap, that is,
length of armature conductor, and N is rotor-speed. The
output coefficient k0 is given as k0 ¼ k1Bg AC, where k1 is
coefficient, Bg is magnetic induction in air-gap, and AC
is ampere-conductor per length of circumference of airgap.
The magnetic induction Bg is limited due to magnetic
saturation of material.
