Difference between Synchronous and induction motor

Question

Accepted Answer

Synchronous motors have constant speed and require external excitation, while induction motors have variable speed and are self-starting.

Synchronous motors have a constant speed determined by the frequency of the power supply.
Induction motors have variable speed depending on the load.
Synchronous motors require external excitation to generate a magnetic field, while induction motors are self-starting.
Synchronous motors are used in applications where constant speed is required, such as in power plants, while induction motors are used in most industrial applications.
Examples of synchronous motors include synchronous generators and synchronous condensers, while examples of induction motors include fans, pumps, and compressors.
