Abstract

Despite the cost raise of rare earth materials, low and medium speed permanent magnet (PM) machines have gained big popularity among wind turbine manufacturers due to their high efficiency and reliability. Ironless stator machines have been proposed in the literature due to their reduced manufacturing cost. However, in the modelling process of the air-cored machines, the rotor loss calculation is generally neglected.
