Nowadays, the motors of woodworking CNC router machines are mainly divided into two categories: stepper motor and servo motor. The stepper motor is a semi-closed loop system. It is economical and could meet the requirements of general customers, so it occupies an important position in the market. On the other hand, the servo motor is a completely closed-loop mode, there is a measurement feedback system in it, so the accuracy is relatively high, the power is large, and the operation is stable. Customers who has higher requirements could choose the machine with the servo motor. Compared with the stepper motor, it is more expensive. At present, there is also a hybrid servo motor on the market, which is an improved version of the stepper motor. So customers could choose a suitable one among the three types based on your requirements.
