The hebern rotor machine was an electro-mechanical encryption machine built by combining the mechanical parts of a standard typewriter with the electrical parts of an electric typewriter, connecting the two through a scrambler it is the first example (though just barely) of a class of machines known as rotor machines that would become the. Thus in all wound rotor dc machines, both motors and generators, the current in the rotor windings is ac and it is the commutator which enables the corresponding dc input or output there are however some notable exceptions. Used rotor balancing machines, wholesale various high quality used rotor balancing machines products from global used rotor balancing machines suppliers and used rotor balancing machines factory,importer,exporter at alibabacom. In a three-phase induction machine, alternating current supplied to the stator windings energizes it to create a rotating magnetic flux the flux generates a magnetic field in the air gap between the stator and the rotor and induces a voltage which produces current through the rotor bars.
