rotor
A rotor ( Latin rotare = 'to turn') is the turning ( rotating ) part of a machine or unit . In particular, one speaks of a rotor when there is also a stator . The investigation and solution of the problems that arise with fast rotation is the task of rotor dynamics as a technical science.
Electrical engineering
In rotating electrical machines , the entire rotating part of the machine is referred to as the rotor or, alternatively, as a rotor such as the squirrel-cage rotor . Depending on the design of the machine, the terms armature or drum armature , inductor or pole wheel are also common.
aerodynamics
In the case of aerodynamically acting rotors, such as the propellers of aircraft (see also air screw ), the term rotor means the entirety of the hub , rotor blades and shaft . Instead of the simple hub, helicopters and wind turbines with blade angle adjustment have a rotor head .
