The invention relates to electrical engineering, in particular to electromagnetic devices. Brushless motor generator is disclosed, which includes a rotor with a permanent magnet and a stator, the windings of which have a rounded cross-section. According to the invention, the rotor is made in the form of a shaft with a permanent magnet fixed on it. The magnetic field vector of the poles of the magnet is perpendicular to the axis of rotation of the shaft. The stator is spherical, covering the magnet, and the axis of symmetry of the stator coincides with the axis of rotation of the shaft. From 1 to 12 windings are wound on the outer spherical surface of the stator; the windings forming the coils with uniformly offset poles relative to each other.

This present invention provides a novel DC dynamo which is characterized by making the magnetic lines of flux pass through an air gap between the rotator and the stator in the same direction, thus the most of armature coils can always receive the electromotive force of the same polarity in the same direction. Therefore, bidirectional energy conversion between the mechanical energy and the electrical energy of the armature coils in series can still proceed in the absence of commutators and induced the armature to generate sufficient electromotive force to conveniently regulate suitable terminal voltages and the ratios of the rotating speed and the moving speed thereof.

A machine and a method for converting between electrical and mechanical energies, the machine may include a stator with first, second (and possibly third) pole faces, a rotor assembly with first, second (and possibly third) rotors connected via a shaft. A magnetic source may be attached to either the rotor assembly or the stator. The source creates a magnetic flux field loop. The machine may include one or more electrical conductors wrapped around a portion of the stator, where the conductors may have multiple portions positioned in a gap between a stator pole face and a rotor. Current flow through all the portions flows across the stator pole face in a same direction. The magnetic source creates a magnetic flux field loop that may rotate with the rotors, causing the conductor portions to pass through the loop, and causing a conversion of energy.
