1. A rotating electrical machine operating by switching of magnetic flux, comprising:
a rotor;
a stator; and
a winding;
wherein said winding comprises at least two phase windings;
wherein said stator comprises at least 2 stator discs, having a magnetic flux predominantly in an axial direction, wherein each stator disc comprising a winding loop from a same phase winding encircling an encircled magnetic structure and enclosing magnetic flux from at least 5 adjacent magnetic poles at an airgap, said winding loop enclosing a total magnetic flux that is larger than the magnetic flux from one individual magnetic pole of a same polarity;
wherein said adjacent magnetic poles are provided in at least one of said rotor and said stator;
wherein said winding loop is securely fixed to said encircled magnetic structure.
