THE CHALLENGE:
Gilmour Space Technologies, an Australian launch services provider, required a high-performance electric motor and inverter solution for a critical onboard application within its launch vehicles. The system needed to meet extreme constraints around weight, packaging, and reliability—while delivering the performance required for spaceflight environments. Off-the-shelf solutions were not viable due to the unique demands of aerospace launch systems.
THE SOLUTION:
Equipmake developed a bespoke high-speed electric motor and inverter system tailored specifically for onboard aerospace application. The solution featured a 20,000 rpm motor paired with a pressurised silicon carbide (SiC) inverter, enabling exceptional power density in a compact, lightweight package.
Five systems were integrated per launch vehicle, with a total of 21 units produced and delivered. The pressurised inverter design ensured optimal thermal and electrical performance while maintaining minimal mass—critical for launch efficiency and payload optimization.
PROJECT HIGHLIGHTS:
- Bespoke 20,000 rpm motor and inverter system engineered for spaceflight
- Advanced SiC inverter technology for high efficiency and compact packaging
- Pressurised design enabling reduced mass and improved reliability
- Five systems deployed per vehicle
- 21 total units delivered to support initial launch program
- Supporting imminent first launch of Gilmour Space vehicle
WHAT THE CLIENT HAD TO SAY:
“It goes without saying that delivering rockets into space is an exceptionally demanding exercise, and one which allows for little margin for error. With a flexible, agile approach and ‘can-do’ attitude in completing the design, build and test of this new electric motor, the team at Equipmake has been great to work with.”
