Synchronous Motor: In this post , the Advantages, disadvantages and applications of synchronous Motor is given in detail.
Advantages of Synchronous Motor
1. Its power factor can be controlled by the control of field current.
Also Read: Physical significance of power factor
2. In certain applications, the fact that its speed is independent of load and applied voltage, may be important.
3. It’s efficiency is slightly higher than that of induction motor.
4. For low speeds and high rating, ( above 500 kW) a synchronous motor is cheaper than induction motor

Disadvantages of Synchronous Motor
1. The need of dc source for excitation (usually a an exciter is mounted on the shaft to provide the excitation)
2. Need of starting and synchronizing
3. Instability
4. Hunting
5. Need of expensive control devices
In view of the above advantages, and  disadvantages, the synchronous motors are used only for low speed, high up speed, high hp requirements.
