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

Is this the sort of thing, petrol heads will lust after in a BEV future?

Sounds an amazing achievement, but then I have very little to compare it with. It's almost like the next arms race, when money and thought is thrown at an issue, it's amazing the speed of development.

"UK-based engineering firm Equipmake is developing what it claims is “the world’s most power-dense permanent magnet electric motor”.

Designed in collaboration with 3D printing specialist Hieta, the so-called Ampere motor will weigh less than 10kg but provide a peak output of 295bhp. For reference, the Jaguar I-Pace’s two electric motors weigh around 40kg each and produce 197bhp.

The Ampere’s 27bhp per kg output gives it a better power density rating than any conventional electric motor on sale.

The unit’s lightness is due mostly to minimal use of metal in its construction, and an innovative 3D-printed casing that is as thin as possible. An added benefit of this construction method is enhanced thermal efficiency, which means the motor can spin faster for longer without overheating.

Despite its impressive performance, the Ampere will command a relatively low list price, given its resource-light construction.

The motor’s development has been funded by the Government’s Innovate UK programme, which gives financial support to UK-based projects.

Working prototypes are expected to be in operation within the next 12 months."

I'm no expert but this development looks like a real step up and if priced as they claim could be a game changer for low volume manufacturers and DIY bods.

600 bhp sounds amazing for 2 motors weighing so little. Stick one on each corner and you will have close to 1200 bhp to play with!

However for me, the most exciting thing is it's still early days. In 10 years who knows what they will develop. In the very near future we may look back on the combustion engine as we do with steam now. WARNING.

stick as suitably geared one of them where the transferbox is and fill the space where the engine was with batteries and away we go DEFENDER 90 TDCI XS,

I hope everyone is well and your land rovers make you happy

sounds really good and as above stick one on each corner for fully independent drive 4 wheel drive and 1200BHP with instant torque the application could be very interesting. such a size makes EV conversion very interesting too. Imagine 4 of those driving a classic defender and handling the braking too? Tank turning like the Rivian? 110 MY23.5 X Dynamic HSE
RR MY23 HSE PHEV
D5 MY19 HSE - Now Sold
D4 MY16 HSE Luxury - Now Sold
D4 MY12 HSE - Gone
D3 MY06 S - Gone but not forgotten
