Large AF Motors for high torque applications
With the growing electrification of working machinery, the electric replacement of high torque low speed diesel engines is required. Based on the physical laws applying to axial flux machines they are an ideal solution for this application. The presentation will give an overview of the developments and technologies of axial flux motors in general. Explaining the pros and cons of different topologies and also comparing them to the established radial flux motor technology. This will be followed by a review of a new large diameter machine developed capable of more than 1000 Nm of continuous torque a with diameter of 55 cm and length of 16 cm.
