Propulsion technology for electric cars is advancing. The vast majority of automotive suppliers present novelties that lower costs for car and commercial vehicle brands. This new electric axle of British gestation promises sports performance with minimal weight.
The electric cars they are becoming a majority. The brands are immersed in a transformation of mobility that requires a high investment to overcome the rivals. The key reason why so many automotive suppliers have joined the development of advanced zero-emission propulsion solutions, new specialized companies have also emerged.
The goal is for manufacturers to reduce the price of electric cars by adopting external technologies. And this electric motor presented by the British specialists at Equipmake has the perfect qualities for any type of model on the market, from a tourism, SUV, sports car to an electric van. Based in Norfolk, the big news is called Axis «Equipmake Ampere 220-E», a drive axle specially developed for high-performance electrics that stands out for offering a very compact design, a true featherweight and performance figures that are difficult to beat, they explain from «Auto Motor und Sport».

The set weighs only 85 kilogramsand includes two 3D printed electric motors -although it can also be just one- with the power electronics, a Silicium carbide and an integrated transmission system that directly drives the vehicle’s axle. The chemistry of the new inverter allows a faster transmission of electrical currentavoiding unnecessary energy losses.
The British have explained that the design of the new Ampere electric motor allows for a significant reduction in weight, to the point that only the motor has a spoked rotor that weighs only 20 kilograms. The electric motor is cooled by a liquid circuit and each one renders a maximum power of 220 kW, maintaining a continuous power of 165 kW, with a maximum turning speed of up to 30,000 rpm. figures that are equivalent to 299 and 224 hprespectively.
With two electric units, maximum power amounts to 440 kWwhich is a true revolution, since it is a transmission shaft capable of offering a power of 598 hp with a maximum torque of 2475 Nm. A really brutal power density that meets all the requirements of any manufacturer, with a system that reduces weight very significantly on the drive sideso its technical applications open up a more than large field.
