UK electrical drivetrain elements producer Equipmake has developed a compact, light-weight, high-power electrical drive system for producers of high-performance EVs.
Weighing just below 20 kg, the Ampere-220 e-axle system has a peak energy of 220 kW, a most motor pace of 30,000 rpm and an influence density of 11 kW per kg—greater than twice that of a traditional electrical motor, in response to the corporate.
The important thing to its efficiency is its mixture of Equipmake’s spoke rotor design with additive manufacturing, permitting Ampere’s metallic construction to be 3D-printed, quite than milled from a strong billet.
Debuted with a twin-motor specification, the Ampere-220 e-axle gives 440 kW peak energy per axle with a complete unit weight of 85 kg. Equipmake may also develop a single-motor e-axle software with 220 kW of peak energy per axle.
“We’ve created the Ampere-220 e-axle by combining it with our personal energy electronics, together with our silicon carbide inverter and transmission system that straight powers the car’s axle,” mentioned Ian Foley, Equipmake’s CEO. “With such an quantity of efficiency in a compact, gentle unit, one which can be ISO 26262-compliant and ASIL-D-ready, it supplies the full off-the-shelf resolution for producers of electrical sports activities automobiles.”
