A wide-body Air Canada aircraft moved between several gates and taxied on a British runway to demonstrate new motors and drives from Chorus Motors plc, Gibraltar.
Two electric motors attached to the nosewheel moved the aircraft, thus eliminating towing and reducing the fuel used on the ground. The system can also reduce turnaround time, noise, and emissions at airports.
Semikron in Germany designed the supercompact electronic module that powers the system. The Chorus Meshcon drive operates with up to 20 or more phases.
Applications are expected in areas as diverse as starter-alternators for cars, conveyors, locomotives, hoists, and robotics. Other uses in aerospace, such as starter generators for jet turbines, are likely to be developed in the near term. One potential use is as a replacement for hydraulic systems where the motor starts and stops frequently, often under load.
