What is one notable benefit of a synchronous motor?

A synchronous motor is particularly valued for its ability to provide power factor correction, which is a notable benefit in various applications. This ability stems from the motor's design, where it runs at synchronous speed with the supply frequency, allowing it to either absorb or supply reactive power to the electrical grid. By supplying reactive power, synchronous motors can help improve the overall power factor of a system, reducing losses and improving efficiency in power distribution.

In scenarios where inductive loads are prevalent, such as in industrial environments, synchronous motors can play a crucial role in mitigating the effects of those loads, facilitating a more balanced power system. This characteristic makes them especially useful in applications where energy savings and system efficiency are critical.

Conversely, while options such as high starting torque, low maintenance, and compact size may have their advantages in some contexts, they do not encapsulate the primary benefit of synchronous motors as effectively as their capability for power factor correction. High starting torque typically is a feature of other types of motors, while low maintenance and compact size aren’t defining traits of synchronous motors compared to alternatives like induction motors.
