The spindle motor is computer laser engraving machine
Choose good laser engraving machine spindle motor The spindle motor is computer laser engraving machine, laser cutting machine and photosensitive seal machine is an important part of the performance of computer laser engraving machine, laser cutting machine and photosensitive seal machine has a vital influence the machine performance.At present, the machining spindle is usually divided into two categories: precision machining spindle and high power to cut off the spindle.Fine machining spindle is characterized by low noise, high speed, height, suitable for machining special fine artifacts, such as seals, nameplates, badges gifts, etc.the prospect of laser engraving machine for sale is very good. Such motor is usually high speed frequency conversion motor, power is small, generally under 250 w, and faults is the ability to cut off the thick material is bad, not to cut off the thicker material.High power to cut off the main shaft, is mainly used for cutting, high power, characterized by large power, strong cutting ability, especially suitable for cutting words, three stereoscopic word, of course also can make the breastpiece, nameplate, seals, etc.Such high power spindle according to the characteristics of the motor can be divided into general frequency high-speed brushless ac motor and a brushless ac motor, the main difference is: A. high speed brushless frequency conversion motor, variable speed range is 70000-60000 revolutions per minute, and generally have highest brushless ac motor speed does not exceed 24000 RPM;the prospect of laser engraver for sale is very good. B. brushless frequency motor rotation of high precision, low wear, low noise, especially the noise is much lower than a brushless ac motor; C. brushless frequency conversion speed regulating motor adopts frequency conversion control technology, is a professional product, long life, and the manufacturer provides one 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 life of about 300 hours to replace carbon brush motor or motor, so the carbon brush ac motor is usually a day also not warranty.http://www.morngraver.com/laser-engraving-machine.html D. 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 and ac machine in smoking or locked-rotor will soon when the burned overloads, and repair.
