1. Stepper driver + stepper motor
The stepping system is currently the most used drive system on the market. The most popular is the three-phase hybrid stepping motor, which accounts for more than 90% of the market share. The reason is that the price is low and it is equipped with a high-segment drive. The effect is good. But the defects are also more obvious, such as: resonance, noise, increase in speed, decrease in torque, prone to losing steps after working for a long time, and excessive temperature rise of the motor.
2. Hybrid servo drive + motor
The use of hybrid servo has not been popular in China. There are many reasons for this. There are not many foreign manufacturers of hybrid servo, and the price has no great advantage compared with AC servo. It can only be used in some special industries. Improvements include: improving high-speed performance, reducing heat generation, and reducing resonance.
3. AC servo drive + AC servo motor
The use of AC servo in engraving machines 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 of the machine tool, electrical appliances, control systems, and transmission systems. It is the same as the barrel principle, the shortest The board determines the amount of water in the barrel, so AC servos are generally used in high-end models. AC servo has: fast response, large torque, high speed, high precision, low heat generation, continuous long-time work, complete alarm system, etc. Disadvantages: Different equipment needs different servo parameters, and the adjustment parameters require high-level technical engineers.
