Unipolar electrical machine for use as DC motor, has rotor whose active part is provided with stellar shaped cross section so that coil is induced by induction fluctuations in gap between rotor and stator to induce pulsating voltage

摘要

The machine has a stator (2) and a rotor (1), which forms a common magnetic circuit and includes an exciter winding. An active part of the rotor has a stellar shaped cross section such that a working coil found in the stator is induced by induction fluctuations in a gap between the rotor and the stator to induce pulsating voltage. Individual stellar spikes of the rotor are interconnected in series connection.
