What type of motor is typically used to raise and lower landing gear?

The type of motor typically used to raise and lower landing gear is often a split field series-wound motor. This motor design provides a good balance of torque and speed control, which are both critical for the precise operation of landing gear systems in aircraft. The series-wound arrangement allows for high starting torque, making it effective for overcoming initial resistance when the landing gear is being deployed or retracted.

Furthermore, split field motors can be adjusted for different operating conditions. They are capable of functioning well over a range of speeds and loads, which is essential given the varying conditions that an aircraft may encounter during takeoff, landing, and taxiing. The robust nature of this motor type also contributes to its reliability, which is paramount in aviation safety.

Other motor types may not offer the same performance characteristics necessary for the specialized task of landing gear actuation, which requires reliability and precise control to ensure safe operation.
