Abstract :
The self-inductance of a rotating spot flux pump is responsible for the drop of output voltage from the pump. The magnitude of this effect referred to as the "armature reaction" has been studied in this paper. It is shown that this reaction is a function of the current generated, the speed of rotation, and the shape of the magnetic poles used in the excitation of the pump. A few suggestions have been given for the construction of pumps with reduced armature reaction.
