TECHNICAL ASPECTS 
FRAME SIZES / HP RATINGS  ENCLOSURES 

Synchronous motors are capable of being operated under a wide range of power factors, both lagging and leading. Hence, it can be used for power factor correction purposes, in addition to supplying torque to driven loads.

Application areas :
1) Because of high efficiency and high speed synchronous motors (above 600 rpm) are well suited for loads where constant speed is required such centrifugal pumps, belt-driven reciprocating compressors, blowers, line shafts, rubber & paper mills etc.

2) Low speed synchronous motors
(below 600 rpm) are used for drives such as centrifugal and screw-type pumps, ball and tube mills, vacuum pumps, chippers and metal rolling mills etc.

3) Used for voltage regulation of Transmission lines.
