The high-speed asynchronous motor is the most simple, easy to manufacture and widely used of all kinds of motors. Its design and manufacture technology is quite mature, and there is no great difficulty in its application. In order to increase the specific power, the following research should be focused on: the speed of the motor should be increased as much as possible under the condition of mechanical strength, and the structure should be made of high temperature resistant, high strength and Light Weight Chin Alloy. High-permeability and low-loss ferromagnetic materials are used to increase the magnetic load of the motor, high-temperature resistant design measures are adopted, high-temperature resistant insulating materials are used to increase the electromagnetic load of the motor, and structural design measures are adopted to reduce the volume and weight of the motor. The gear reducer can be improved by using the mature gear reducer technology. On the premise of satisfying the transmission power, through the structure optimization design, using high-strength structural materials, as far as possible to reduce the volume and weight of reducer. Frequency converter compared to the ordinary inverter, the use of frequency converter has two very favorable conditions: power battery DC power supply, can be directly carried out DC-AC inverter, less than the ordinary inverter a rectification link, the number of power devices is greatly reduced, the circuit complexity is low, the conversion efficiency is high, and the reliability is high. The hot drawing process uses steam to heat the fiber and then stretch it 4-5 times. It is completed by drawing machine, drawing machine is divided into import and export two parts, equipped with two sets of roller, driven by two asynchronous motor, motor power is 18.5 kw and 5kw, each equipped with two frequency converters for speed adjustment (can be adjusted separately or 2 groups of speed proportional synchronous regulation) .
