Which type of motor is most likely to have an armature brake?

The most likely type of motor to have an armature brake is a landing light retraction motor. An armature brake is typically used in applications that require rapid stopping or holding of the motor when it is de-energized. In the context of a landing light retraction motor, this feature is crucial because the motor must quickly and precisely position the landing lights during landing and takeoff phases, where swift response is necessary for safety and operational efficiency.

In contrast, starter motors are designed primarily for high-torque applications during engine start and do not typically require an armature brake, as they function only briefly and do not need to hold a position afterward. Inverter drive motors are usually used for variable speed applications and operate under different principles, focusing on controlling speed rather than needing a braking feature. Lastly, generator motors, which convert mechanical energy into electrical energy, usually do not have an armature brake incorporated into their design because their operational context does not require such quick stops or holding capacities. Thus, the specific operational requirements and safety considerations associated with landing light retraction make the armature brake particularly suited for that application.
