sünkroonmootori

A sünkroonmootor is a type of AC electric motor that rotates at the same speed as its magnetic field. This speed is determined by the frequency of the AC power supply and the number of poles in the motor. Unlike induction motors, sünkroonmootors do not rely on induced currents in their rotor to produce torque. Instead, their rotor is magnetized, either by permanent magnets or by a DC current supplied through slip rings.

The rotor's magnetic field then locks onto the rotating magnetic field of the stator, forcing the rotor to turn in sync. This synchronous operation means the motor's speed is constant regardless of the load, as long as the load does not exceed the motor's pull-out torque. This makes sünkroonmootors ideal for applications requiring precise and constant speed control, such as in clocks, timers, and some types of industrial machinery. They are also known for their high efficiency and ability to improve the power factor of an electrical system, often being used for power factor correction. The starting of a sünkroonmootor can be more complex than an induction motor, sometimes requiring a special starting mechanism or operating as an induction motor during startup.
