The difference between servo motor and stepper motor, and use, that is, when to use servo motors, when the stepper motor,
Stepper motor can be completed, servo motor can do, so servo can be seen as stepping advanced version.Step selection is usually due to cost considerations and wiring (relatively simple); compared with the start, servo system has many advantages, accurate positioning, fast response, closed-loop control (without losing step), self protection system perfect. But the prices are expensive, wiring and settings are much more complicated
Servo motor accurate point is servo system, should be sold in general are sets of motor plus drive, high precision and stability!Famous is Panasonic servo, generally closed loop control system! Of course, the price is high!
The step is simple, the price is low, and it is suitable for the open-loop control that is not required! With more embroidery machine when the above XY frame drive, stepper motors are generally sold separately, the market is also very versatile drive.
Stepper motors and servo motors are used for position control with little speed,
