Various types of valves and actuators are used on aircraft to perform a variety of critical functions, from regulating the flow of fuel to the engines to controlling airflow into the aircraft's environmental control systems. The physical location of the motor within the aircraft/vehicle system, often in extreme environments, requires maximum performance for a given motor frame size. Typical design considerations include: 1) selection of magnet materials to ensure that the magnet strength does not decrease with increasing temperature; 2) lamination materials to ensure that the motor can withstand the temperature range to which it is exposed; 3) leads - connecting the motor to The wires connected to the driver board ensure that they remain flexible in extreme cold conditions and withstand melting in extreme heat conditions. Teflon materials generally meet these requirements, but the design characteristics of the motor must be considered to ensure high performance operation over a wide range of temperature extremes throughout the aircraft/vehicle life cycle. In high-speed/extreme vibration environments, precise control is essential. The performance of the motor is directly proportional to the performance of the system. Every potential parameter that affects performance during operation must be taken into account in the motor design. Because they offer high power density in a small, low-weight design, custom brushless DC motors are ideal for these applications, where accuracy is a key goal and encoder feedback is often used to ensure correct positioning and self-correction.
