Abstract
A segment for supporting electromagnetic coupling elements of a stator or rotor of an electrical machine comprises a plurality of elongate laminations which are stacked in a first direction to form a lamination stack with elongate edges of the laminations defining opposite first and second major faces of the lamination stack. The segment comprises a plurality of elongate compression devices passing internally through the lamination stack in the first direction and arranged to compress together the laminations in the lamination stack.

A rotor for an electrical machine, the rotor comprising:
- a hub arranged so that the rotor can rotate with respect to a stator of the electrical machine about an axis of rotation;
- a rim comprising a plurality of electromagnetic coupling elements for electromagnetic coupling with a stator of the electrical machine;
- a plurality of spokes arranged between the hub and the rim so as to mechanically couple the hub with the rim.
A stator for an electrical machine, the stator comprising:
- a hub arranged so that a rotor of the electrical machine can rotate with respect to the stator about an axis of rotation;
- a rim comprising a plurality of electromagnetic coupling elements for electromagnetic coupling with a rotor of the electrical machine;
- a plurality of spokes arranged between the hub and the rim so as to mechanically couple the hub with the rim.
