Application of synchronous motors
1. They are used in power houses and substations in parallel to the bus-bars to improve the power factor.
2. Synchronous motors are also used to regulate the voltage at the end of transmission lines.
3. In factories having a large number of induction motors, or other power apparatus operating at lagging power, they are employed to improve the power factor.
4. Typical applications of high speed synchronous motors are such drives as fans, blowers, dc generators, lines shafts, centrifugal pumps and compressors, reciprocating pumps and constant speed frequency changers, rubber and paper mills etc.
