Whether used as singlemotor or multimotor drives, they are suitable for applications where loadindependent speeds or synchronous operation are required under strict observance of defined speed relations within a large frequency range, such as in the: •Chemical fiber industry (spinning pumps, godets, drive rollers)
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.
micro spinning mills in a single room. micro spinning mills in a single room integrated spinning mill will soon become the first in the world where a farmer can enter the gates with a bale spourt disc get price [Chat Online] where are applied of computer in spinning mills.
Jan 29, 2013· Fiber spinning Textile and paper mill 5. Supply Frequency to the synchronous motor is controlled from the inverter which receives its firing pulses from a frequency controlled oscillator. The machine will exhibits conventional behavior. Up to base speed the motor operates at constant torque and above base speed are obtained by clamping the ...
The true synchronous mode is used only in multiple synchronousreluctance and permanentmagnet motor drives, in applications such as paper mills, textile mills, and fiberspinning mills, because of the problems associated with hunting and stability.
Jul 11, 2019· Synchronous motor finds application where operating speed is less (around 500 rpm) and high power is required. For power requirement from 35 kW to 2500 KW, the size, weight and cost of the corresponding three phase induction motor is very high. Hence these motors are preferably used. Ex Reciprocating pump, compressor, rolling mills etc.
EE 2403 SPECIAL ELECTRICAL MACHINES UNIT I – SYNCHRONOUS RELUCTANCE MOTOR 1. What is a synchronous reluctance motor? It is the motor driven by reluctance torque which is produced due to tendency of the salient rotor poles to align them selves with synchronously rotating field produced by .
May 12, 2010· 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.

Apr 15, 2017· Operation of variable frequency control of multiple synchronous motor drive A selfcontrolled synchronous motor drive employing a load commutated thyristor inverter is shown in Fig. In large power drives wound field synchronous motor is used. Medium power drives also employ permanent magnet synchronous motor.
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.
The Difference Between Synchronous and Asynchronous Motor are explained considering factors like type, slip, requirement of additional power source, slip ring brushes,cost, efficiency, power factor, current supply, speed, self starting, effect in torque because of change in voltage, applications.
Jul 17, 2016· Hi, as the name suggests, a synchronous machine is a magnetically locked machine that runs at constant speed irrespective of load, or does not run at all (if it does not have an induction machine coil built in). This makes the application related ...

Rocznik.
are the applications of vernier motor x Direct drive application x Application which required high torque at low speed. is synchronous reluctance motor. It is the motor driven by reluctance torque which is produced due to tendency of the salient rotor poles to align themselves synchronously rotating field produced by stator.
With synchronous motor technology, speed is directly proportional to AC input frequency – for example, at 120 Vac, 60 Hz, an AC synchronous motor will turn at 72 rpm. This speed can be varied by varying the frequency, although most applications simply use gearing or a belt or chaindrive system to achieve the desired load speed.
