Why is maintenance required for synchronous motors used as condensers?

The maintenance of synchronous motors used as condensers is primarily necessary due to the presence of moving parts that require service. Synchronous motors have rotors that rotate in synchrony with the frequency of the electrical supply, and these rotors are essential for their operation. The moving parts can wear out over time due to friction and mechanical stress, which can lead to decreased efficiency, potential failure, or safety hazards if not regularly serviced.

Regular maintenance ensures that bearings, windings, and other mechanical components are in good condition and function correctly. This service can include lubrication, alignment checks, and inspections to prevent breakdowns that could disrupt operations.

While factors like efficiency, heat generation, and mechanical complexity can impact the overall performance and operational considerations of synchronous motors, the critical need for maintenance in this context specifically arises from the requirement to manage the mechanical integrity of the moving components.
