Large synchronous motors in rating of 25 000 hp and higher have been used in Thermal Mechanical Pulp (TMP) plants. Applications to Jordans, grinders and vacuum pumps drives are alos common. As compared to an induction motor, a synchronous motor can be designed more specifically for the ...
Synchronous motors are like induction motors in that they both have stator windings that produce a rotating magnetic field. Unlike an induction motor, the synchronous motor is excited by an external DC source and, therefore, requires slip rings and brush
aRare-Earth Permanent Magnet Synchronous Motor (PMSM) has a rapid development on its application in industries and civil lives for its simple structures, small dimensions, high efficiency and fine power factor. 稀土元素永久磁铁同步电动机 (PMSM) 有在它的应用的迅速发展在产业和民用生活中为它的简单的...
This paper presents the state of the art in the area of industrial applications of sensorless control for permanent-magnet synchronous motor (PMSM) drives. A new emerging technology is becoming mature to come to the market, based on high-frequency signal injection, that makes it possible to achi...
This paper presents an overview of IEEE 1349-2011, a guide that assists individuals, organizations, and suppliers with the application of motors in Class I, Division 2 and Class I, Zone 2 locations, where flammable gases and vapors may occasionally be present. AC synchronous and induction motor...

In cement industry many application machines such as excavators, induced draft fan, mills, conveyors, crushers and kilns which are driven by induction and synchronous motor are controlled by variable frequency drive. The control process through variable frequency drives leads to efficient speed control,...
