Choose good computer engraving machine spindle motor

Pay attention to the computer engraving machine spindle motor. Spindle motor is an important components of computer engraving machine, the performance of computer engraving machine has vital effects on the performance of the machine. Machining spindle is usually divided into two categories: precision machining spindle and high power to cut off the spindle. 1, fine machining spindle is characterized by low noise, high speed, height, suitable for machining special fine artifacts, such as seals, nameplates, badges gifts, etc. Such motor is usually high speed frequency conversion motor, power is small, under 250 w. Weakness is the ability to cut off the thick material is bad, not to cut off the thicker material. 2, high power to cut off the spindle, is mainly used for cutting, high power, is characterized by large power, strong cutting ability, especially suitable for cutting yu, three stereoscopic word, of course also can make the breastpiece, nameplate, seals, etc. Such high power spindle motor according to the characteristics of general can be divided into frequency high-speed brushless ac motor and A brushless ac motor, the main difference is: A, high speed brushless frequency conversion motor, speed range is 70060000 r/min, and generally have highest brushless ac motor speed is not more than 24000 r/min: B, frequency conversion brushless motor rotation of high precision, wear small, low noise, noise is much lower than A brushless ac motor; C, locked-rotor characteristic frequency conversion brushless motor is good, because the inverter with current limiting circuit, blocked for a short period of time not burning motor, brush with ac machine in the seams or locked-rotor when smoke burned soon, and repair; D, brushless frequency conversion speed regulating motor adopts frequency conversion control technology, is a professional product, long life, manufacturers provide 1 year free replacement, later also can be used to replace the high-speed bearing the machine maintenance, and brushless ac motor due to the use of electricity fee to life around 300 hours have to replace the motor or motor carbon brush, so the carbon brush ac motor is usually a day also not warranty.
