  • Axial flux motors - E-Mobility Engineering

    The input costs can be reduced but the conversion costs are not wellestablished and so can be highly variable. In principle, an axial flux motor can be competitive with the radial version through lower material costs for a given power-to-weight ratio, but the conversion cost is the big factor. ... (480-plus kph). Three axial motors generate 500 ...
