Superconducting aircraft motors

Power density and power-toweight ratio have always been very near the top of the list of essential attributes for aircraft propulsion systems, particularly in those elements that work at the sharp end of converting stored chemical energy into thrust (writes Peter Donaldson). Rockets aside, the gas turbine engine has yet to be beaten in this respect. In the electrified...

Axial flux motors

Axial flux motors have many EV design advantages over their radial flux counterparts, as Nick Flaherty explains. A new type of motor is gaining traction in the e-mobility sector – the axial flux type. For many years they have been used in stationary applications such as elevators and agricultural machinery, but over the past decade a number of developers have been working on improving...
