Synchronous motor basics: what you need to know
03/06/2015 · In an industrial setting, large synchronous motors, besides performing useful work, can serve to modify a harmful power factor. Often nonworking synchronous motors are kept online only because this is less expensive than deploying power factor correction capacitors. Due to the inertia of rest, a large synchronous motor with a heavy armature is not selfstarting. Such motors can be .

Synchronous Motor : Working Principle, Types, and Appliions
The moment of inertia of rotor stops the largesized synchronous motors from selfstarting. Because of this inertia of the rotor, it is not possible for a rotor to get in sync with the stator's magneticfield at the very instance power is applied. So some additional mechanism is required to help the rotor get synchronized. Induction winding is included in the large motors which generate ...
