Equipmake Ampere

E-axles are becoming one of the favored methods for rapid integration of electric powertrains into vehicle platforms and have been deployed across applications ranging from micromobility to trucks and hypercars. Targeting the latter of these markets is the Ampere-220 from UK-based Equipmake. The compact and power-dense e-axle makes 440kW of peak power in an 85kg package incorporating motors, inverters and transmission.

The basis of the Ampere-220 axle is a pair of high power density, 220kW permanent magnet motors constructed using Equipmake's proprietary spoke motor topology, which according to company founder Ian Foley has been subject to extensive optimization to improve thermal management and cooling.
