Motors and Actuators for Military/Aerospace Systems
Sierramotion Application Solutions
Sierramotion motor and actuator designs for space and defense include special materials, processes and performance. Most applications require operation at -50° to +70°C ambient temperatures. This requires correct materials inside the motor and may drive certain magnet materials and magnet compositions, some of which cannot be used in Space and may disintegrate over time.
Thermal design is the most important factor under these environmentally challenging applications. Having a good thermal model for the motor and understanding how materials interact to ensure the motor will survive. The only way to have success is to build from previous experience taking requirements and turning them into solutions.
