Abstract

The invention relates to a method of a spinning frame synchronous frequency converter and a rare-earth permanent magnetic synchronous motor. The method comprises the steps of supplying working voltage to the synchronous frequency converter and the rare-earth permanent magnetic synchronous motor by a power supply; controlling the rare-earth permanent magnetic synchronous motor to run by controlling the synchronous frequency converter; controlling the rare-earth permanent magnetic synchronous motor to drive a spinning frame main shaft to rotate. By adopting the synchronous frequency converter and the rare-earth permanent magnetic synchronous motor, motor inversion and shaking caused by a transmission device after the motor is started can be effectively avoided, broken yarns in the spinning process can be reduced, the yarn quality is improved, and an energy-saving purpose is realized by utilizing the characteristic of the permanent magnetic motor.

Description

technical field [0001] The invention belongs to the field of spinning frames, and in particular relates to a method for synchronous frequency converters and rare earth permanent magnet synchronous motors of spinning frames. Background technique [0002] At present, ordinary frequency converters and rare earth permanent magnet asynchronous motors are commonly used in the spinning frame to drive the main shaft. After the motor is started, this transmission method will easily cause the motor to reverse and vibrate, which will cause the yarn to break during the spinning process. yarn, affecting the yarn quality. Contents of the invention [0003] The object of the present invention is to address the above-mentioned defects and provide a method for synchronous frequency converter and rare earth permanent magnet synchronous motor of spinning frame with energy-saving effect, which can not only avoid motor reversal, but also reduce yarn breakage and improve yarn quality . [00...
