How to choose spindle motor of woodworking engraving machine spindle motor

How to choose the spindle motor the spindle motor is an important component of the computer engraving machine, and its performance has a vital impact on the performance of the computer engraving machine. Machining spindles are usually divided into two categories: precision machining spindles and high-power cutting spindles. 1, the characteristics of fine processing spindle is low noise, high speed, high precision, suitable for processing particularly fine workpiece, such as seal, nameplate, badge gifts, etc. This kind of motor is usually a high-speed variable frequency motor with low power, generally below 250 W. The disadvantage is that the ability to cut thick materials is poor, and it is not suitable for cutting thicker materials. 2. High-power cut-off spindle is mainly used for cutting off and high-power carving. It is characterized by high power and strong cutting ability. It is especially suitable for cutting characters and three-dimensional characters. Of course, it can also make badges, nameplates, seals, etc. This kind of high-power spindle can be generally divided into brushless frequency high-speed AC motor and brushed AC motor according to the characteristics of the motor. The main differences of woodworking engraving machine are: A. Brushless variable frequency motor has high rotating speed and variable speed range of 700-- 60000 rpm, while the maximum rotating speed of General brush AC motor does not exceed 24000 rpm: B. Brushless variable frequency motor has high rotating precision, low wear and low noise, its noise is much lower than that of brushed AC motors; C. The brushless variable frequency motor has good locked-rotor characteristics. Due to the special current limiting circuit on the frequency converter, the short-term locked-rotor will not burn the motor, the brush AC machine will soon smoke and burn when it is overloaded or blocked, and it cannot be repaired; D. The brushless variable frequency motor adopts variable frequency control technology for speed regulation. It is a professional-grade product with long service life. The manufacturer provides free replacement for one year. In the future, the motor can be maintained by replacing high-speed bearings, however, the brush AC motor has to replace the motor or the motor carbon brush because the service life of the motor is about 300 hours, so the carbon brush AC motor is usually not guaranteed for one day.
