Aerospace motors are AC induction, squirrel cage motors used on spacecraft and aircraft for both commercial and military use. Motors may range from fractional horsepower to 30 or 40 horsepower. These motors must be extremely reliable, small, lightweight, low vibration, and low noise level and typically designed for operation on 400-hertz power.
Typical applications for these motors are air conditioning
condensers and evaporators, air handling fans, fuel and hydraulic pumps, landing
gear actuators, wind shield wipers, hoists, turrets and antenna drives.
