Stable running of double-twister motor for energy saving and enhancement of economic returns

Energy saving of electric motor is an important factor for the improvement of economic returns in textile industry.In this paper,the principle of voltage reduction and energy saving of asynchronous motor under light-load condition is discussed and the effect of the change of end voltage on the speed of rotor is analyzed,along with brief description of the mechanism and operation of the voltage stabilizing and energy saving system of the motor.Digital simulation of asynchronous motor equipped with stablizer used for twisters is performed and the effect on energy saving is investigated with a function of input voltage,rotation speed,power consumption of the motor.When the motor is running on the basis of energy saving,the influence of reduction of rotating speed on productivity should be considered.The methods for the textile industry to enhance its economic returns have been investigated.
