木工雕刻機的主軸電機特點與分類
來源：http://www.tj9.net 時間：2021-09-08
作為木匠雕琢機設備的配件就是主軸電機。主軸電機是電腦雕琢機的主要構成部件，其功能對電腦雕琢機整機的功能有著到關主要的影響。加工主軸凡間分為兩類：精細加工主軸和大功率割斷主軸。
As a carpenter's carving machine equipment center, the accessory is the spindle motor. Spindle motor is the main component of computer engraving machine, and its function has a major impact on the function of the whole computer engraving machine. Machining spindles are divided into two categories: fine machining spindles and high-power cutting spindles.
1、精 密加工主軸的特點是低噪音、高轉速、高精度，合適加工特殊精 密的工件，如印章、銘牌、胸牌禮物等。此類電機凡間為高速變頻電機，功率較小，普通在250W以下。缺陷是割斷厚的資料的才能較差，不合適割斷較厚的資料。
1. Precision machining spindle is characterized by low noise, high speed and high precision. It is suitable for machining special precision workpieces, such as seals, nameplates, badges, gifts, etc. This kind of motor is a high-speed variable frequency motor with small power, usually below 250W. The defect is that the ability to cut thick data is poor, and it is not suitable to cut thick data.、
2、大功率割斷主軸，首要用于割斷、大功率雕琢，特點是功率大，切割才能強，特殊合適割字、三維立體字，當然也可以制造胸牌、銘牌、印章等。此類大功率主軸依據電機的特征普通可分為無刷頻高速交流電機和有刷交流電機，其首要區別是：
2. The high-power cutting spindle is mainly used for cutting 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 manufacture chest plates, nameplates, seals, etc. This kind of high-power spindle can be generally divided into brushless frequency high-speed AC motor and brush AC motor according to the characteristics of motor. The main differences are:
A、無刷變頻電機轉速高，變速局限為700--60000轉/分鐘，而普通有刷交流電機Highest轉速不超24000轉/分鐘
A. The speed of brushless variable frequency motor is high, and the speed change is limited to 700-60000 R / min, while the high speed of ordinary brush AC motor does not exceed 24000 R / min
B、無刷變頻電機扭轉精度高，磨損小，噪音低，其噪音大大低于有刷交流電機
B. Brushless variable frequency motor has high torsion precision, low wear and low noise, and its noise is much lower than that of brush AC motor
C、無刷變頻電機堵轉特征好，因為變頻器上有非凡的限流電路，短工夫的堵轉不會銷毀電機，而有刷交流機在超負荷運轉或堵轉時會很快冒煙銷毀，且不成修復
C. Brushless variable frequency motor has good locked rotor characteristics, because there is an extraordinary current limiting circuit on the frequency converter, the locked rotor in a short time will not destroy the motor, while the brush AC machine will smoke and destroy quickly during overload operation or locked rotor, and it cannot be repaired
D、無刷變頻電機采用變頻節制技能調速，是級產物，壽命長，廠家供應1年包換，今后還可以經過改換高速軸承對電機進行維護，而有刷交流電機因為運用電機壽命大約在300小時就得改換馬達或電機碳刷，所以碳刷交流電機是也不保修。
D. Brushless variable frequency motor adopts variable frequency control technology for speed regulation. It is a professional product with long service life. The manufacturer provides free replacement for one year. In the future, the motor can be maintained by changing the high-speed bearing. However, the brush AC motor has to change the motor or motor carbon brush because the service life of the motor is about 300 hours, so the carbon brush AC motor is not guaranteed for one day.
