The difference between the servo motor and the step motor, and the usage
Step motor and servo motor are used for position control, low speed, Simple, inexpensive, suitable open loop control! With more and more time, the XY frame is driven by the embroidery machine, and the step motors are generally sold separately, and the market drivers are also very generic. Servo motor is the servo system accurately, should be a complete set of sales motor and drive, the precision is high and stable! The more famous is the panasonic servo, general is the closed-loop control system! Of course the price is high!
The servo motor will be able to do so, so servo can be seen as stepping into the advanced version. In general, it is because of cost and wiring (simpler). Compared to the beginning, the advantages of servo system are many, the location is accurate, the response is fast, the closed-loop control (not losing step), the self-protection system is perfect. However, the price is expensive, the wiring and setup are much more complicated.
The servo is generally used in high-power high-precision situation, the step power is small, the accuracy is poor, the cheap
