2nd Quarter 2014Electrical switching & drive systems & components
In the aviation industry a wide range of applications are controlled by actuators. For example they are used to control and limit velocity and engine speed by adjusting levers and flaps. It is important that they achieve very high dynamic forces yet be lightweight and fit into small spaces. They also have to withstand ambient conditions such as strong vibrations, heat and cold.
Sitec Aerospace, based in Bad Tölz, Germany, supplies actuators to the two largest aircraft manufacturers. Sitec uses brushed motors by maxon motor for its actuators. Actuators and valves have very diverse applications in aircraft and they have to meet different requirements. Motors have to be equally robust. The most important requirements are an optimal volume/performance ratio, low power consumption, long life and resistance against temperature, vibrations, impact and corrosion.
Customised and robust motors with direct gearing on the shaft and high life span make maxon motors the ideal choice for aviation applications. These are equipped with powerful permanent magnets. The core of the motor is the globally patented ironless maxon winding. Compared to conventional DC motors, maxon DC motors feature a pure copper winding that rotates without armature iron. With this lightweight rotor, inertia is very small and acceleration is very high. There is no magnetic detent – very important for positioning drives because the rotor can stop in any position. In addition to the electric actuators, maxon motors are used inside aircraft as part of an electromechanical drive that makes it easier for passengers to close the luggage compartments above the seats.
