UK electrical drivetrain parts 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 velocity of 30,000 rpm and an influence density of 11 kW per kg—greater than twice that of a standard electrical motor, based on the corporate.
The important thing to its efficiency is its mixture of Equipmake’s spoke rotor design with additive manufacturing, permitting Ampere’s steel construction to be 3D-printed, moderately than milled from a stable 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 also can develop a single-motor e-axle software with 220 kW of peak energy per axle.
“Now we have created the Ampere-220 e-axle by combining it with our personal energy electronics, together with our silicon carbide inverter and transmission system that instantly powers the car’s axle,” stated Ian Foley, Equipmake’s CEO. “With such an quantity of efficiency in a compact, mild unit, one which can be ISO 26262-compliant and ASIL-D-ready, it supplies the overall off-the-shelf answer for producers of electrical sports activities vehicles.”
