Synkronimotorissa

Synkronimotorissa is a type of electric motor where the rotor rotates at the same speed as the rotating magnetic field of the stator. This synchronous speed is determined by the frequency of the alternating current supplied to the stator and the number of poles in the motor. Unlike induction motors, synkronimotorissa have no slip between the rotor and the stator field. This inherent characteristic makes them highly efficient and allows for precise speed control.

The rotor of a synkronimotorissa typically consists of permanent magnets or electromagnets, which are synchronized with the stator's magnetic field. When AC power is applied to the stator windings, it creates a rotating magnetic field. This field then interacts with the rotor's magnetic field, causing the rotor to lock onto the rotating field and spin at the synchronous speed.

Synkronimotorissa are known for their constant speed operation, regardless of load variations, as long as the load does not exceed the motor's torque capacity. This makes them ideal for applications requiring consistent speed, such as in clocks, timers, and certain types of industrial machinery. They are also used in applications where power factor correction is important, as they can be operated to provide a leading power factor. Their construction can be more complex and costly than that of induction motors, and they require a starting mechanism to bring the rotor up to near synchronous speed before it can lock in.
