Axial Flux Electric Motor May Not Take You Back to the Future, But How’s 0-60 in Under 3 Seconds?
This ain’t yo daddy’s Flux Capacitor. A “stealthy” (read: “completely unheard of” — stealthy would imply actively trying to stay under the radar) itty-bitty start-up company from down under has come up with an in-wheel electric motor that might just make electric cars the outright kings of speed.
The “Axial Flux 3-Phase AC Induction Wheel Motor,” as Evans Electric calls it, not only has an important sounding name, its inventors are coming up with some pretty ballsy claims that cars equipped with them could get from 0-60 mph in under 3 seconds. That’s the kind of acceleration that could, quite literally, rip your eyeballs from their all-important perch in front of your brain.
I tried to find it, but there is almost no other information available besides the video below and the one source article… so take this one with a grain of salt. Reportedly, each Axial Flux motor produces about 95 horsepower (70 kW). With 4 of them on a car that’s nearly 400 HP… 400 HP plus the instant, high torque of an electric motor? Sounds like a winning combination.
The idea of in-wheel motors is certainly not new. About a year and a half ago, I brought you information about a wheel created by Michelin that not only has the motor in the wheel, but the suspension too. As I said at the time, “When you’ve eliminated the need for an engine, a transmission, a drive shaft, a differential, an exhaust system, shock absorbers and a suspension system within the chassis of the car, not only can you start to imagine entirely different car shapes, you can have both front and rear “trunk” storage, have a lot more room for people in the cabin, and create new safety features to boot.”
Clearly in-wheel motors (and suspension) have a lot going for them. The EVN report claims that Evans Electric will be unveiling an actual car using the Axial Flux motors on all 4 wheels within the next month and that the car will be a “well proven model with a long history of World Rally Championship success.” Apparently the car will also be supplied with 400 volts of A123 lithium-ion nanophosphate battery packs.
