asünkroonmootoriga

Asünkroonmootoriga, also known as an induction motor, is a type of electric motor where the electric current in the rotor is produced by electromagnetic induction from the stator's rotating magnetic field. This means that there is no direct electrical connection to the rotor. The motor's speed is always slightly less than the synchronous speed of the rotating magnetic field, hence the term "asynchronous."

The stator winding, when supplied with alternating current, generates a rotating magnetic field. This field induces currents in the rotor conductors. The interaction between the rotor currents and the stator's magnetic field produces a torque that causes the rotor to spin. The speed difference between the rotating magnetic field and the rotor, known as slip, is essential for torque production.

Asünkroonmootorid are widely used in industrial applications due to their robustness, reliability, and relatively low cost. They come in various designs, including squirrel cage and wound rotor types, each suited for different operating conditions and starting torque requirements. Their simplicity of construction and low maintenance needs make them a popular choice for a vast array of machinery, from pumps and fans to conveyor belts and machine tools. They are also common in household appliances.
