The synchronous technology

Winning partnership

The adjective synchronous comes from the fact that the rotation speed of the rotor is directly connected to the mains frequency. The rotor is made of a permanent magnet.

As a conseguence of the interation between the rotating magnetic field produced by the current flowing through the stator windings and the field produced by the rotor magnet, the rotor itself starts to rotate at a speed identified as the synchronous speed.

And as such, seeing as the mains frequency (Hz) is always constant, the speed at which the rotor rotates is as a consequence absolutely constant (at Hz=50 => RPM=3000).

This construction and the working principle of the synchronous motor offer great advantages in terms of improved efficiency, which can be translated as low energy consumption and as constant performance.
