The synchronous speed of a motor can be calculated using the formula: ( \text{Synchronous Speed} (N_s) = \frac{120 \times f}{P} ), where ( f ) is the frequency in hertz and ( P ) is the number of poles. For a four-pole motor connected to a 50Hz supply, the synchronous speed is ( N_s = \frac{120 \times 50}{4} = 1500 ) RPM. Thus, the synchronous speed of the motor is 1500 revolutions per minute.
An induction motor rotating at higher than synchronous speed would be generating power, thus would be a generator. No motor operating as a motor runs above synchronous speed.
When an induction motor is pushed over synchronous speed it will become a generator and will deliver power back to the utility.
A 60Hz synchronous motor spins at synchronous speed - if it's a two pole motor it will spin at exactly 1800 rpms. An asynchronous motor will spin at a speed lower than the power supply frequency - a symilar asynchronous motor may spin at 1700 rpms.

1)Synchronous motors are those that run only at Synchronous speed i.e. constant speed. But Motor can run in various speeds. 2)Synchronous motors runs at same speed of magnetic filed. but if one consider case of induction motor the rotor rotates at different speed than revolving magnetic field. there is slip between field and rotor.
synchronous motor is a constant speed motor because it will only run at a synchronous speed or not at all.the speed can be changed by changiing the frequency only ns=120f/p
A synchronous motor runs at synchronous speed, so there is no slip, or zero slip.

mainly alternator,synchronous motor comes under the synchronous machine.a synchronous motor is not a self starting motor.if a synchronous motor moves with more than synchronous speed then it acts as a synchronous generator.
When an induction motor is pushed over synchronous speed it will become a generator and will deliver power back to the utility.
Synchronous motors run at synchronous speed. An induction motor that has the same number of poles must run at a sub-synchronous speed to create a second magnetic field (a field that is at a different phase angle) to generate torque.
Number of poles and supply freqency determines speed of synchronous motor. For speed control of such motors Variable Freqency Drives(VFD) are used.
A 60Hz synchronous motor spins at synchronous speed - if it's a two pole motor it will spin at exactly 1800 rpms. An asynchronous motor will spin at a speed lower than the power supply frequency - a symilar asynchronous motor may spin at 1700 rpms.
Slip in an induction motor is the difference between the synchronous speed of the magnetic field and the actual rotor speed, expressed as a percentage of the synchronous speed. It is calculated using the formula: Slip = (Synchronous Speed - Rotor Speed) / Synchronous Speed. Slip speed, on the other hand, refers to the actual difference in RPM between the synchronous speed and the rotor speed. This slip is crucial for the operation of the motor, as it is what allows the rotor to develop torque.
