Permanent magnet synchronous motor (PMSM) drives are used for high-performance applications like servo and robotics drives, electric vehicle, spinning and rolling mills, packaging industries due ...
Synchronous motors have a unique and merited position as the most efficient electrical drive in the industry and are often 1-2% more efficient than induction motors. Power Factor Correction Synchronous motors can operate at leading power factors, providing VARs to the power system, reducing demand charges often caused by induction motors.
The true synchronous mode is used only in multiple synchronous-reluctance and permanent-magnet motor drives, in applications such as paper mills, textile mills, and fiber-spinning mills, because of the problems associated with hunting and stability.
The next process is spinning. Before the thread is ready for final spinning it is thinned down in two or three stages by processing it on a fly or speed frame. A motor with smooth acceleration is necessary to rive Considerations for Textile Industry in this frame. The drive motor should be capable of working in high ambient temperatures.

VFD in Textile Machines With the continuous improvement of the technical level of textile machinery mechatronics, AC variable speed has become a trend. Almost without exception applied in most of the new development of textile machinery products in the AC induction motor frequency control devices.
Jul 16, 2010· Best Answer: A synchronous electric motor is an AC motor distinguished by a rotor spinning with coils passing magnets at the same rate as the alternating current and resulting magnetic field which drives it. Another way of saying this is that it has zero slip under usual operating conditions. Contrast this with an induction motor, which must slip in order to produce torque.
