Synchronous motors are constant speed motors. They run at the synchronous speed of the supply. They are generally used for constant speed operation under no load conditions such as to improve the power factor. Synchronous motors have fewer losses than induction motors at a given rating. The speed of a synchronous motor is given by N_s = 120f / p. Using this, we can calculate the motor rpm.
As you can see, the synchronous speed depends on the frequency of the supply and the number of poles of the rotor. Changing the number of poles is not easy, so we do not use that method. However, with the invention of solid-state devices, the frequency of the current fed to the synchronous motor can be varied. We can control the speed of the synchronous motor by changing the frequency of the supply to the motor. We can use a combination of rectifiers and inverters to control the speed of synchronous motors.

thank s for synchronous s fomula
Can't clear idea about how two poles system will rotate 90 degrees in 1/2f sec.
same here
what the software are you used for this tutorial
Prefect🥰
🙏 thank
Synchronous speed is the rotational speed of the rotor. Regardless of the number of poles of the rotor, the rotating speed of the rotating magnetic field is given by f (Hz) x 60 (seconds) = 60f (revolution).
For a 2-pole rotor (North and south poles), the rotor will rotate at 60f.
For a p-pole rotor (p must be multiple of 2), the rotor will rotate at 60f x 2/p = 120f/p

Sorry I don't know English.... In 180 degree (half cycle),we used 1/2f.ok...but why are you used 1/2f in 90 degree...
I think 4 pole created 2 cycle per one rotation...
but how?
