A consortium, consisting of several European companies, was commissioned to modernize a run-of-the-river hydroelectric power plant in Central Europe. The new machine group, consisting of a 12 MW Kaplan turbine and generator, required a speed increasing gearbox with an integrated turbine thrust bearing. Installation space was limited – a conventional single-stage planetary gearbox with approx.…

NOVAGEAR celebrates the 10th anniversary. A big thank to all our customers and partners for your trust and loyalty. Andre Thuswaldner

Our newest gearbox development for a 48V WHR prototype comprises a minimum quantity lubrication for the gears. The lube oil is precisely dispensed, dependent on speed and temperature, and directed to the gear flanks in atomized condition. With this adaptive lubrication concept, drag and churning losses are reduced by more than 90 percent, compared to…

A European turbine manufacturer entrusted NOVAGEAR with the development and design of a test bench gearbox. The nominal speed of 56’000 rpm posed great challenges to the design as well as to the manufacturing. With a triple path power split concept, the gear mesh velocity could be limited to less than 200 m/s. A total…

Mr. Tim Limacher, a student at the High School of Mathematics and Science in Zurich, has successfully completed his internship at NOVAGEAR AG. He says: “I got the opportunity to apply and extend my theoretical knowledge in a specific project. I used various design and calculation tools for the development of a high-speed gearbox. This…

NOVAGEAR has completed the developed of a novel gearbox for a plug-in hybrid electric vehicle (PHEV) in collaboration with a US customer. The concept, a two-stage planetary gear in combination with a torque vectoring module for the wheel-selective torque control, was derived from a gear synthesis.   The electric motor, a water-cooled permanent-magnet synchronous motor,…

The Academic Motorsport Club Zurich (AMZ) conquered two overall victories at this year’s «Formula Student Germany» in Hockenheim. The two racing cars «Eiger» and «Gotthard Driverless» prevailed against the international competition with 3,700 students from 115 teams. It is AMZ’s first double victory in its «Formula Student» history, the largest engineering competition in the world.…

Wheel robots, which are used for the exploration of celestial bodies, reach their limits on steep or unstructured terrain. A jumping form of locomotion not only extends the operating range, but is also significantly more energy efficient in environments of low gravity. At the ETH Zurich, the focus project team SPACE BOK has set itself…

In June 2018, Novagear completed a prototype gearbox intended for use in an electric transport vehicle. The gearbox has been developed and designed from scratch, based on the functional and performance specification of the customer. The maximum power is 175 kW and the operating speed of the electric motor varies between 4'500 and 12'000 rpm.…
