ACsähkömoottori

ACsähkömoottori refers to an alternating current electric motor. These motors operate by using the alternating nature of the supplied current to create a rotating magnetic field within the motor's stator. This rotating field then induces a current in the rotor, which in turn generates a magnetic field. The interaction between the stator's and rotor's magnetic fields produces the torque that causes the rotor to spin.

There are several primary types of AC motors. The most common is the induction motor, also known as the asynchronous motor. In an induction motor, the rotor rotates at a slightly slower speed than the rotating magnetic field of the stator, hence the term "asynchronous." Another significant type is the synchronous motor, where the rotor rotates at the exact same speed as the stator's magnetic field. Synchronous motors often require a separate DC excitation current for the rotor.

AC motors are widely used in a vast array of applications due to their reliability, efficiency, and relatively simple construction. They power everything from household appliances like refrigerators and washing machines to industrial machinery, pumps, fans, and electric vehicles. The voltage and frequency of the AC power supply determine the motor's operating speed and power output. Their versatility and robustness make them a cornerstone of modern technology and industry.
