Electric motors and inverters

The Voltabox electric motors and inverters for the Artega Scalo were developed based on the latest technologies from aerospace with computer-based extreme value procedures. Results include perfect adjustment to the application and a particularly high efficiency.

The Artega Scalo is powered by two rear-mount electric motors with a total output of 300 kW (peak output 390 kW) and a torque of 575 ft-lb. The motor mass is only 66 lbs each, which leads to an outstanding performance density of 2.3 kW/lb. The maximum motor speed is at 12,500 rpm, the maximum efficiency at 6,900 rpm is up to 95%. On request, a version with an outstanding efficiency of 98% is available.

The Voltabox high-efficiency machines are supplied and controlled via two newly developed inverters with an efficiency of up to 93%. A version with special silicon carbide transistors even achieves a maximum energy conversion of 98.8%.
