Information

This presentation will share with the aerospace community the recent development of an integrated drive system for turboprop hybridization within the EU H2020 CleanSky program. The drive system enables green-taxiing of the turboprop while on the ground with the engine off, and works as a generator when the turboprop is in the air. Some of the key features of the developed system include a high-speed permanent machine (up to 18,000rpm), high power density (11.8kW/L for the power converter, 35.3kW/L and 7.2kW/kg for the machine active parts), integrated cooling design for high-temperature operation (>130ºC ambient temperature) and sensorless control.
YASA: e-motors for hybrid and electric vehicles & aviation needsYASA designs and manufactures highly efficient electric powertrain solutions for hybrid and electric vehicles and has a growing reputation for driving innovation to meet the emerging needs of various Aerospace industry applications. Come talk to us to find out more. For a given power & torque requirement, YASA can deliver significantly smaller, lighter and more efficient electric motors, controllers and integrated electric drive units than any other competing technology. Furthermore, the motor technology is inherently lower cost than the competition when purchased in volume due to the motors exceptionally high utilisation of magnetic material and YASA's advanced manufacturing technology. The high performance YASA motors and controllers are suitable for range of markets and applications, and excel in the toughest environments where eficiency,  weight and space are critical for the end-user. In 2018, YASA officially opened its 100,000 unit per annum e-motor and controller automated serial production facility in Kidlington near Oxford, UK.
