Woodworking engraving machine spindle motor features:
The spindle motor is an integral part of computer engraving machine , its performance on the overall performance of computer engraving machine has a critical influence . Machining spindle is usually divided into two categories: precision machining spindles and spindle power cut .
1 , precision machining spindle is characterized by low noise, high speed , high accuracy, especially suitable for fine machining of the workpiece, such as seals , nameplates , badges and other gifts. Such motors are usually high-speed variable frequency motor , less power , generally in the 250W or less. The disadvantage is the poor ability to cut thicker materials , it is not suitable for cutting thicker materials .
2 , power off the spindle , is mainly used for cutting , high-power engraving , is characterized by power, cutting ability, especially for cutting word , three-dimensional characters, of course, can produce badges , nameplates , seals and so on. Such high-power spindle motor according to the characteristic frequency can be divided into high-speed brushless AC motor and brush AC motor , the main difference is : A, high speed brushless frequency conversion motor , variable speed range of 700 - sixty thousand RPM / min , and generally have the highest brush AC motor speed does not exceed 24 000 rev / min : B, high- precision brushless motor rotation frequency , low wear, low noise, the noise significantly lower than its brush AC motor ; C, brushless frequency conversion motor stall characteristics good , because there are special limiting circuit on the drive , short of burning the motor will not stall , while the exchange machine brush when overloaded or smoke will soon stall burned, and not repairable ; D, no brush motor with frequency inverter speed control technology , is a professional-grade products , long life , the manufacturers provide 1 year free replacement, after high-speed bearings can also be maintained by replacing the motor , and the AC motor brush motor life due to the use of about 300 hours have to replace the motor or brushless motor, brushless AC motors are usually one day so no warranty.
