Állórész

Állórész is a Hungarian term that translates to "stator" in English. It refers to the stationary part of an electric motor or generator. In an electric motor, the stator's primary function is to produce a rotating magnetic field. This field then interacts with the magnetic field of the rotor, causing the rotor to turn and produce mechanical power. In a generator, the stator typically contains coils of wire that cut through a magnetic field, generating electrical current.

The stator is usually constructed with a laminated iron core designed to channel the magnetic flux efficiently. Within this core are slots where windings of insulated copper wire are placed. The arrangement and connection of these windings determine the motor's characteristics, such as its number of poles and phase configuration (e.g., single-phase or three-phase). For AC motors, the stator windings are energized by an alternating current supply, creating the necessary rotating magnetic field.

The design and construction of the stator are critical for the performance, efficiency, and reliability of the electrical machine. Factors such as the material of the core, the size and shape of the windings, and the cooling method all play significant roles. The stator must be robust enough to withstand the electromagnetic forces and operating temperatures encountered during use.
