Maxon Motor’s brushless DC motors, spur gearheads and resolver combinations help to achieve comfortable temperatures inside the Boeing 787 long-distance aircraft, which is also known as the Dreamliner.

A total of 48 motors from Maxon are installed in the climate control system of each Dreamliner aircraft. The air is not drawn from the jet engines under pressure, but instead fresh air is taken from the outside atmosphere.

Specific motor motions were required for the complex air-conditioning system; this included drives for the cabin ventilation, for cooling the electronics and for closing and opening the air inlet on the outside of the aircraft.

The cabin ventilation system consists of 36 shut-off valves that are driven by Maxon EC 45 flat DC brushless motors.

Key benefits of product application

  • Cabin atmosphere and pressure conditions are improved, making long-distance flights more tolerable for passengers.
  • Maxon’s motors withstand temperatures of -55°C to +85°C and the vibrations during take-off and landing.
  • The EC 45 light brushless motors are able to fit into very small spaces and can achieve speeds of up to 20,000rev/min.
  • Thanks to their open design, the motors offer excellent heat dissipation at high torques.
  • The stator of the flat motors installed in the air-conditioning system has been adapted: the printed circuit board has been modified with low-temperature Hall sensors and the motor has been given a special protective conformal coating.
  • A modified stator magnetic path prevents movement when the motor is unpowered, further improving overall efficiency.
