A leading automotive electrification specialist has launched a new electric drive system.
Equipmake’s Ampere-220 e-axle is a compact, lightweight, high power electric drive system for manufacturers of high-performance electric vehicles.Debuted at Cenex-LCV, it combines one of the most advanced 3D-printed electric motors in the world with all power electronics, including the company’s own silicon carbide inverter, and an integrated transmission system in a compact unit that directly powers the vehicle’s axle. This brings a step change in off-the-shelf performance for electric sports cars and supercars.
Ian Foley, Equipmake CEO, said: “Equipmake has always been at the forefront of innovation in electric motors, with our APM range offering class-leading power densities thanks to their compact, lightweight designs. Ampere showcases the next leap, and combined with our own power electronics, including our silicon carbide inverter, and transmission system, we have created the Ampere-220 e-axle.
“With such a huge amount of performance in a compact, lightweight electric drive unit, one that is also ISO 26262-compliant and ASIL-D ready, Ampere-220 e-axle provides the total off-the-shelf high performance electric solution for manufactures of electric sports cars and supercars. It further underlines Equipmake’s position as a leading provider of state-of-the-art electrification systems to the automotive industry,” he said.
The e-axle features the Ampere electric motor, drawing on both Equipmake’s world-leading expertise in electric motors – featuring a spoke rotor design, which has also featured in the Ariel HIPERCAR in the form of Equipmake’s APM motor – and pioneering knowledge in additive manufacturing and thermal engineering from Bristol-based HiETA.
It has a peak power of 220kW (295hp) and a maximum motor speed of 30,000rpm. Weighing just under 20kg, it offers power density of 11kW per kg, which is more than twice that of a conventional electric motor.
The key to its performance is its combination of Equipmake’s spoke design with additive manufacturing, allowing Ampere’s metal structure to be 3D-printed, rather than milled from a solid billet. more to this article at WhichEV - link - the ever brilliant Shumaila Iftikhar - link - more like this (electric hypercars) - link
