Reseña del libro "Results of experimental studies of electrical contact"

Compared to other types of electric machines, unipolar generators have a number of advantages. Simplicity of design, high overload capacity, high efficiency, absence of ripples in the current and voltage curve, possibility of direct connection to the turbine, etc. The use of superconducting winding in unipolar generators makes it possible to significantly increase the magnetic field and the generator's E.D.S.. As research has shown, it is necessary to use electric arc moving contact in unipolar ones. This kind of contact can operate up to 350 m/s, and when certain conditions are created, the voltage drop in the arc contact can be reduced to 1-3 V at current densities up to 100 - 200 A/cm2. Achievement of such rotor speeds and losses in the contact make it possible to consider the unipolar generator as a highly efficient source of electric energy directly connected to the turbine, which is also one of the positive factors in the creation of power units of large capacities.
