Electrical machine with double-sided lamination stack

A generator for a wind turbine comprising:

• at least one rotor comprising an inner rotor core and an outer rotor core;
• and
• at least one double-sided stator comprising an inner stator side including an inner stator winding and an outer stator side including an outer stator winding, the inner stator side and the outer stator side comprising a double-sided lamination stack,
• wherein the at least one double-sided stator is concentrically disposed between the inner rotor core and the outer rotor core of the generator.

A generator for a wind turbine comprising;

• at least one rotor comprising an inner rotor core and an outer rotor core;
• and
• at least one double-sided stator comprising an inner stator side including an inner stator winding and an outer stator side including an outer stator winding, the inner stator side and the outer stator side comprising a double-sided lamination stack, wherein the double-sided lamination stack is configured to enable the magnetic flux to flow radially between the inner stator side and the outer stator side, and
• wherein the generator is a direct-drive permanent magnet generator.
