Abstract: An electric motor comprises a housing, a magnetic rotor and a stator which comprises at least one circuit board. The magnetic rotor comprises a disk with circumferentially arrayed magnetic poles. The circuit board on each side comprises one layer of circumferentially arrayed coil windings arranged in pairs, thus each pair made as a spiral that extends from a center of a start coil winding to a center of an end coil winding with the same turn direction of the spiral in relation to each of centers. The layers are the same in transparent view and shifted angularly in such a way thus centers of the start coil windings from one side of the circuit board coincided and electrically connected by via's with centers of the end coil windings on the other side of the circuit board.

Abstract: According to the present invention, a brushless DC electric motor comprising a magnetic rotor, stator and housing. The magnetic rotor comprising a disk installed perpendicular to a shaft and having circumferentially arrayed magnetic poles. The stator comprising at least one circuit board parallel to said disk and said circuit board serves as part of said housing and having circumferentially arrayed coil windings for producing electromagnetic fields.
