Abstract

An electromechanical converter for automatically adjusting driving torque from an engine of a vehicle comprises a rotor, a stator, and a set of windings. The set of windings comprises main windings, subsidiary windings, and auxiliary windings. The rotor is housed within a stator, comprises a pole. A hub of the stator shaft is engaged to auxiliary stator and transfers energy from the engine to output. Each coil of the main and subsidiary windings is wound on each pole. Each coil of the auxiliary windings is wound between poles. The stator is separated from the rotor by gap. An output shaft is connected to auxiliary stator and it is engaged to the stator shaft. The comparative rotating of the rotor and stator creates current at the windings of the rotor and the stator.
