Earlier this 12 months, UK-based YASA amazed the world by displaying off an axial flux electrical motor that weighed simply 13.1 kg (29 lb) and was rated at 550 kW (738 hp), for an power density of 42 kW per kg. Now it’s again with a brand new and improved model of that motor that weighs much less — 12.7 kg (28 lb) — and is able to a staggering 750 kW (1018 HP) peak energy, which is definitely a world document for power density at 59 kW per kg.
So what’s an axial flux motor anyway? Is it by some means associated to the legendary flux capacitor within the Delorean that starred within the film Again To The Future? No, it isn’t. Based on Wikipedia,
“An axial flux motor is a geometry of electrical motor development the place the hole between the rotor and stator — and due to this fact the path of magnetic flux between the 2 — is aligned parallel with the axis of rotation, moderately than radially as with the concentric cylindrical geometry of the extra widespread radial flux motor.
“With axial flux geometry, torque increases with the cube of the rotor diameter, whereas in a radial flux the increase is only quadratic. Axial flux motors have a larger magnetic surface and overall surface area (for cooling) than radial flux motors for a given volume.”
How The YASA Motor Works
Three years in the past, after Mercedes-Benz purchased YASA, we reported that the axial flux motor is the mind baby…
