ABSTRACT:
In a shaftless spinning rotor assembly wherein the spinning rotor is the rotor of an axial field motor, an improved transfer of power and improved running properties are attained by forming the stator windings in channels which extend substantially radially in the stator core and are enclosed over at least a portion of their length by magnetically conducting material. As compared with known gap windings, the windings can be placed in multiple layers while at the same time avoiding marked graduations in permeance and in the specific current density so that eddy currents in the rotor can in turn be reduced and rotor heating remains within reasonable limits. The stator is preferably formed of multiple component parts which allows optimized selections of materials.
