Abstract: A rotating electrical machine operating by switching of magnetic flux comprises a rotor (10), a stator (20) and a winding, having at least two phase windings. The electrical machine comprises at least 5 discs being either rotor discs (12) or stator discs (22), having a magnetic flux in the axial direction. The stator discs and rotor discs are interleaved with each other via airgaps along an axial direction. The winding loop encloses magnetic flux from n>2 magnetic poles, where the winding loop length is shorter than 2*n*d, where d is the airgap width distance. The two end cap discs are mechanically connected by a stiff mechanical structure (80B) which mechanically transfers apart of the axial magnetic attraction force acting on one of the two end cap discs to the other of two end cap discs.

Abstract: An electrical machine (1) operating by switching of magnetic flux comprises a rotor (10), a stator (20) and a winding (30). The stator has at least two stator discs (22) magnetically connected in series via rotor discs (12). The electric machine topology implements the magnetic gearing effect, and has simple winding loops (32) enclosing magnetic structures (70). The magnetic structures are securely fixed to the winding.

Abstract: An electrical machine (1) operating by switching of magnetic flux comprises a first magnetic structure (10), a second magnetic structure (20) and a winding (30). The first and second magnetic structures are arranged movable relative to each other along a predetermined motion path (4) and have respective sections (12,22) interleaved with each other via more than 4 air gaps. The first magnetic structure presents at each air gap a variable magnetic permeability. The second magnetic structure presents at each air gap a variable magnetic permeability and/or permanent magnet poles. Magnetic periodicities of the first and second magnetic structures are equal. For each of the air gaps, most of the magnetic flux passes at each instant in the same direction. The winding has a respective loop (32) provided either around respective section in the direction of the predetermined motion path, or along respective section along an entire closed predetermined motion path.
