High speed spindle motor

Abstract

The invention discloses a high speed spindle motor. The high speed spindle motor is a two-pole asynchronous motor, the driving voltage is 400 V, the frequency is 0 Hz-350 HZ, the rated current is 0.45 A, and the motor comprises a shell and a cover plate fixed on the shell; the shell is internally provided with a spindle winding, a motor rotor, an output shaft and a steering selector switch as well as a power switch, the spindle winding is fixed in the shell, the motor rotor is fixed on the output shaft, and the output shaft is connected with a rotor; and the steering selector switch is electrically connected with the spindle winding coil, and the power switch is electrically connected with the spindle winding coil. The high speed spindle motor provided by the invention has the advantages that the volume is small, the weight is light, the noise are low, the energy dissipation is low, the maximum revolving speed can achieve more than 15000 rpm, and the high speed spindle motor can meet the spindle driving requirements of various high-speed spinning machines.

Description

technical field [0001] The invention relates to a high-speed spindle motor. Background technique [0002] The twisting spindle speed of a modern high-speed spinning machine can usually reach 10,000rpm or more, and the positioning quantity of a single machine exceeds 200 spindles. As early as 2000, European companies applied high-speed spindle motor technology to the false twister drive of high-speed draft texturing machines, which was unanimously recognized by domestic and foreign customers. The direct advantages brought by this driving method are high efficiency, energy saving and low noise. It has played a positive role in reducing costs, saving energy, and improving the production environment. [0003] The high-speed spindle motor technology developed by our company is developed based on the advanced spindle motor technology in Europe. It has the advantages of small size, stable speed, low energy consumption, low noise, good heat dissipation, and long life. Since more...

AI Technical Summary

Problems solved by technology

The dragon belt is driven by a high-power motor, which not only makes a lot of noise during operation, but also consumes a lot of energy due to the long path of the transmission wheel combination

The combination of mechanical parts of the transmission mechanism is complicated, there are many repeating units, and the damage rate is also high

When any transmission unit fails, the entire equipment must be stopped for replacement, seriously affecting production efficiency

Since the spindle shaft relies on the tension of the dragon belt to compress the transmission, the tension of the dragon belt must be adjusted frequently, and the wear is also very serious. It is necessary to stop the machine to correct the tension of the dragon belt almost every month. The life of the ordinary dragon belt can only last for one year. about
