Free QuoteGood to Know: A synchronous motor is the same machine as Alternator or synchronous generator. For example, A synchronous motor can be operated as a synchronous generator (alternator) without changing the rating and design. i.e. When the machine converts the input electrical power into output mechanical power, it is known as a synchronous motor.
When the rotor reaches near synchronous speed, the DC excitation is applied to the rotor field winding and the motor locks into synchronism. In this method, the motor initially starts as an induction motor using the damper winding. This winding also helps in damping the oscillations due to sudden changes in load.
Such synchronous motor that is specifically used to improve the power factor is called a synchronous condenser. Frequency Changer: A synchronous motor is used to run an alternator or synchronous generator to supply having a different frequency. Such a synchronous motor is known as a frequency Changer.
Synchronous motors are inherently not self starting. They require some external means to bring their speed close to synchronous speed to before they are synchronized. This motor has the unique characteristics of operating under any electrical power factor. This makes it being used in electrical power factor improvement.
In an induction motor, the stator windings generate a rotating magnetic field (RMF) that also induces a current in the rotor. In a synchronous motor, the stator only generates RMF. The rotor's magnetic field magnetically locks with the revolving RMF and rotates at the same speed known as synchronous speed. Click image to enlarge
The core has axial slots for holding the three-phase alternating stator field winding called armature winding. The stator's armature winding is supplied with 3-phase power through its input terminal. It is responsible for generating the rotating magnetic field (RMF). The rotor is the rotating part of a synchronous motor.
