What is a rotor assembly?

A rotor assembly is a crucial component in various mechanical systems, such as helicopters, wind turbines, and electric motors, that facilitates rotation. It typically consists of a rotor, which is the rotating part, along with supporting structures like bearings and hubs. In helicopters, for example, the rotor assembly enables lift and maneuverability, while in electric motors, it interacts with magnetic fields to generate motion. The design and efficiency of the rotor assembly are vital for the overall performance of the system it serves.
