Synchronous Motors  
         
   
" GE " make Synchronous Motors are constant speed machines i.e running at its synchronous speed.

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.
 
       
 
DC motors requires a basic understanding of the design and operating characteristics of the various types available: the series motor, the shunt motor, and the compound motor. Each type has unique operating characteristics and applications.
