Wirnik
Wirnik is the rotating component of a machine in which mechanical energy is transmitted or transformed during operation. In electrical machines such as motors and generators, the wirnik carries windings or magnetic poles that interact with the stator’s magnetic field to produce torque or induce voltage. The term originates in Polish and is widely used in Polish engineering literature; in English, the corresponding element is typically called the rotor.
Rotor types in electric machines include the wound rotor, where windings on the rotor are connected to
Most rotors are built from laminated electrical steel to reduce eddy current losses; they are mounted on
Beyond electric machines, the term wirnik also appears in turbomachinery and aviation, where the rotor denotes
