When the engraving machine manufacturer customers consult and understand the equipment, the salesperson often asks the customer whether to choose the stepper motor or the servo motor. Relatively speaking, the price of the stepper motor will be much cheaper. So, how should the customer use a stepper motor driver? Depending on the current of the motor, a driver greater than or equal to this current is used. A subdivided drive can be used if low vibration or high precision is required. For high torque motors, use high voltage drives as much as possible to achieve good high speed performance.
Secondly, the woodworking machine stepper motor is also divided into two phases and three phases. The 2-phase motor has a low cost, but the vibration at a low speed is large, and the torque at a high speed is rapidly lowered. The 3-phase motor has less vibration and high-speed performance, which is 30~50% higher than that of the 2-phase motor. It can replace the servo motor in some occasions.
