Abstract
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.

A brushless motor, including:
- a rotor with a permanent magnet, the permanent magnet being rigidly fixed to a shaft of the rotor,
- a stator, the stator having a rotational symmetry and covering the permanent magnet, and
- one or more windings, each winding being wound about an outer surface of the stator to form a concentric sphere surrounding the stator;
- wherein poles of the permanent magnet are oriented such that a magnetic field vector of the poles is non-parallel to an axis of rotation of the shaft, while an axis of the rotational symmetry of the stator coincides with the axis of rotation of the shaft,
- wherein any consecutive winding of the one or more windings forms a new concentric sphere having a radius greater than a radius of earlier concentric spheres formed by an earlier one of the one or more windings.
