Electric vehicle (EV) drivetrain and power systems specialist Equipmake has unveiled the HPM-400, an advanced high power, short duration electric motor designed for applications in the space, aerospace and marine sectors. The electric motor debuted during the Future Propulsion Conference recently held in Solihull, U.K.

Originally engineered as a rocket fuel pump, the HPM-400 electric motor offers a maximum speed of 20,000 rpm, peak power of 400 kW, and maximum torque of 250 Nm in a 40 kg unit equipped with silicon carbide inverter technology. Ultra-lightweight and capable of withstanding incredible acceleration, the motor has been revamped mechanically to withstand the pressure from within during transitions from atmosphere into a vacuum.

According to Ian Foley, Equipmake CEO, “HPM-400 keeps air pressure inside and has been completely redesigned mechanically to withstand the pressure from within when it goes from atmosphere into the vacuum. That has resulted in a super compact cylindrical package — conventional inverters being square — with a carbon fiber shell to keep pressure in and weight down. It all adds up to an advanced high power, low weight motor/inverter that’s at home in space, in the air or in water.”
