Abstract
A stator operable to generate a rotating magnetic field for an electrical rotating machine, the stator comprising at least one circuit board with electrically conductive portions formed thereon, the electrically conductive portions connected with a multiphase configuration, wherein a phase comprises: on a first face of the circuit board(s) electrically conductive portions arranged as a plurality of elements, an element comprising a radially extending radial portion having: connected at a proximal end thereof a proximal portion, the proximal portion extending therefrom with a directional component in a first angular direction; and connected at a distal end thereof a distal portion, the distal portion extending therefrom with a directional component in a second opposed angular direction, whereby proximal and distal are defined relative the centre of rotation of the magnetic field and said angular direction is defined about said centre of rotation; and on a second face of the circuit board(s) electrically conductive portions comprising corresponding elements, whereby the proximal portion extends with a directional component in the second opposed angular direction and the distal portio…
