Classification of micro mold engraving machine drive system

1. Stepper driver + stepper motor Stepper system is currently the most used drive system on the market. The most popular is the three-phase hybrid stepper motor, which accounts for more than 90% of the market share. The reason is that the price is cheap. , The effect is good when it is equipped with a Leicai high-resolution driver. However, the defects are also obvious, such as: resonance, noise, speed increase, torque reduction, long-term work is easy to lose steps, motor temperature rise is too high, etc.

2. Hybrid servo driver + motor hybrid servo has not been widely used in China. There are many reasons for this. There are not many manufacturers of hybrid servo in foreign countries, and the price does not have a great advantage compared to AC servo. Used in some special industries. Improvements include: improving high-speed performance, reducing heat generation, and reducing resonance.

3. AC servo driver + AC servo motor The use of AC servo in the engraving machine is still relatively small, the main reason is that the price is relatively high. In addition, the application of AC servo has certain requirements for the structure, electrical appliances, control system and transmission system of the machine Just like the principle of wooden barrels, the shortest board determines the amount of water in the wooden barrels, because some AC servos are generally used in high-end models. AC servo has: fast response, large torque, high speed, high accuracy, less heat, continuous long-term work, complete alarm system, etc.

Disadvantages: Different equipment needs different servo parameters, and the adjustment of parameters requires high-level technical engineers.
