1. Step driver step motor
Stepping system is the most used drive system on the market at present. The most popular is the three-phase hybrid stepping motor, which accounts for more than 90% of the market share, because the price is cheap and has a good effect with the Lesai high segmentation drive. But the defects are also more obvious, such as: resonance, noise, speed improvement torque reduction, long-time to work is easy to lose the step, the motor temperature rise is too high.
2. Hybrid servo-drive motor
The use of hybrid servo in China has not been popular, there are many reasons, foreign manufacturers do hybrid servo is not many, and the price compared with AC servo is not very great advantage, can only be used in some special industries. Improvements are: improve high-speed performance, reduce fever, reduce resonance.
3. AC servo driver AC servo motor
AC servo in the use of engraving machine is less, the main reason is that the price is higher, the application of ac servo for the structure of machine tools, electrical appliances, control system, transmission system has certain requirements, like the piece of barrel principle, the shortest board determines the amount of barrel water, because some ac servo is generally used in high-end models. AC servo has: fast response, large torque, high speed, high precision, less heat, lasting for a long time to work, complete alarm system, etc. Disadvantages: different equipment should use different servo parameters, adjust the parameters require a high level of technical engineers.
