Electrical machine with double-sided lamination stack

摘要

The machine includes a rotor with an inner rotor core and an outer rotor core and a double-sided stator with an inner stator side and an outer stator side. The double-sided stator is concentrically disposed between the inner rotor core and the outer rotor core of the wind turbine generator. The double-sided stator is configured to enable at least a portion of magnetic flux to be shared between the inner stator side and the outer stator side. Examples of particularly useful embodiments for the machine include wind turbine generators and ship propulsion motors.
