New type of energy-saving electric drive: the most efficient way to save energy.

There are known DC and AC electric drives with excitation control, containing negative feedback circuits for speed and flow derivative. In such drives, with an increase in the number of elements included in them, the efficiency always decreases proportionally to the number of links included in them. . Further, the power consumption will also decrease as the number of links in the chain with other consumers increases. The device described below belongs to the field of electrical engineering, namely to electric drives with speed feedback. The drive uses a parallel oscillating circuit in which the current resonates. When the current resonates in a parallel oscillatory circuit, the total current in the branched section of the circuit where the armature of the DCm motor is located can be many times higher than the active current in the non-branched section of the circuit where the armature of the generator is located. In this case, the power generated by the full current will be converted into useful work in the DCm armature, since in the constant magnetic field of the DCm armature disk at full current (active and reactive) an Ampere force will occur, causing the disc to rotate.
