Statorivälja

Statorivälja refers to the rotating magnetic field produced by a stator in an electric motor. The stator is the stationary part of an electric motor, and it contains windings that, when supplied with alternating current, generate a magnetic field. This magnetic field rotates at a synchronous speed determined by the frequency of the electrical supply and the number of poles in the stator windings.

The principle of the statorivälja is fundamental to the operation of AC induction motors and synchronous motors. In an induction motor, the rotating magnetic field induces currents in the rotor, which then experiences a torque and rotates. In a synchronous motor, the rotor is designed to lock onto the rotating magnetic field and rotate at the same synchronous speed. The speed and direction of the rotating magnetic field can be controlled by adjusting the frequency and phase of the applied AC power. This control is achieved through devices like variable frequency drives (VFDs), allowing for precise speed regulation of the motor. The strength and characteristics of the statorivälja are influenced by factors such as the current flowing through the windings, the number of turns, and the geometry of the stator core. Understanding the statorivälja is crucial for designing, analyzing, and troubleshooting electric motors.
