Staatorikääminä

Staatorikääminä refers to the stator winding in an electric motor or generator. The stator is the stationary part of the motor, and the winding is a coil of wire that carries electric current. When current flows through the stator winding, it creates a magnetic field. This magnetic field interacts with the magnetic field of the rotor, which is the rotating part of the motor, to produce torque and cause rotation.

In AC motors, the stator winding is typically connected to the AC power supply. The alternating current creates a rotating magnetic field within the stator, which then induces current in the rotor and causes it to spin. The configuration and number of turns in the stator winding determine the motor's voltage, current, and power characteristics.

In DC motors, the stator winding, often called the field winding, creates a stationary magnetic field that interacts with the magnetic field produced by the rotor winding. This interaction generates the torque for rotation.

The material used for the stator winding is usually copper due to its excellent electrical conductivity and relatively low cost. The wire is insulated to prevent short circuits between turns and between the winding and the stator core. The design and placement of the stator winding are critical for the efficient and reliable operation of the electric machine.
