UK firm to launch 'world's most power-dense' EV motor

[voyager]

Norfolk-based Equipmake is developing a 295bhp power unit that weighs less than 10kg

I'm developing one also. Until either of us actually make one though, it's just talk.

Use of the term "bhp" for a standalone motor tells me much about the technical competence of this amazing Norfolk-based innovator /s

I'm sure that we will never hear about this again.

It was not Equipmake that used those units. It's the

Notice UK in that address. Some say they still ride horses.

Also you guys start with Metrics before barking on neighbours.
This forum is Imperial based s**t. Mostly.

Well, that is indeed a better source. At least the wrong terminology (bhp = brake horsepower, which is nonsense on a standalone motor with no car or brakes attached) is absent.

However, the company's claims are still highly suspect. Namely, they claim a motor with 20kW/kg of output as being " four times as much power as a similarly sized permanent magnet motor". Then destroy their own argument by stating that the Model S 6-year old motor is 8.4 kW/kg (which is only a factor of 2.4, not 4). And they obviously don't want to compare to the Model 3 motor, which is newer and more efficient. And the Equipmake electric motor can only get heavier when components/structures, reinforcement required for real-world application/installation at high powers are included in the Equipmake weight numbers. On balance, I don't think this is going to be the breakthrough that is being implied.

BTW, I wasn't criticizing the term "hp" as a unit (although I certainly could). I was commenting on the unit "brake hp". And just to seal the deal, I actually live in a country using the metric system, so you can stop the "you guys" nonsense. Also, remember that Tesla, the world leader in EV technology, was started in a country still using the "backward" Imperial system of measurement.
