1. Different
control precision stepper motor drive 'niche' concept. Two phase step Angle of stepper motor is 1. 8 degrees, yes, but now, 64 subdivision drive is also very common. Note that this time, the motor is 200 * 64 = 12800 pulse on a business trip. The common ac servo on market, encoder is 2048 or 2500 line. Of course, there are 17 encoder of the motor, however, stepper drives also have 256 subdivision. In terms of resolution, ac servo or higher, but far from floor. And, since mean control precision, then the used servo should know, servo dynamic repeatability is how many times the resolution. In terms of conventional design, type selection, the reproducibility index x 5 as the resolution of the servo feedback. In this way, the control precision of servo really better than servo?
2, low frequency characteristics of different
when the stepper motor fine fraction reaches more than 32, basic is no the problem of low frequency vibration. The servo wants to maintain an accurate and stable low-speed used people should know how hard it is to adjust parameters (Good as long as the speed, do not place, do a little)
3, different frequency torque feature
for torque, need to add that the servo itself is not keep the torque, and stepper motor has a torque. The difference is that the servo motor of the so-called static, is actually a process of dynamic balance, the motor won't really stop in the designated position,So shall the repeatability of ac servo to the 3 - feedback resolutionFive times, and stepper motor can be higher resolution than reproducibility)。

4, overload capacity different this have nothing to say, but for the moment to waste, or a little advice. Many stepping drive provides a flow function, without all the torque output, can reduce the current, reduce the torque.
5, different running performance
lost step is, indeed, step motor fatal flaw, but the server can not consider deceleration curve? You really give a step signal is a try, how electricity opportunities of jitter. But trembled to tremble, eventually will stop in the right position, it does better than step by step. If the positioning control, the jitter doesn't matter, if it is a process control, who dare to use so much?
6, different speed response performance
because ac servo can have instant high torque output, so performance may be better than the stepping to accelerate, but panasonic added to 3000 RPM in a few milliseconds, first tried to speak again, ok? And said to the response, it is said that the essence of the ac servo defects & ndash; —Lagging behind. Response 2 milliseconds, general motors, speed loop position loop response has rarely see the data, is thought to be 8 milliseconds. Servo always hand when it comes to quick start stop, limit its response frequency, and stepper motor basic need not consider the problem of response time. Use stepper motor can be easily done 100 times a second start-stop, each move 20 microns, with servo you can give it a try.
stepping servo, and it doesn't matter, have their own applicable occasions, in general, big load, the application of high speed, don't use stepper motors, but the occasion of low load and low speed, high subdivision of the stepping performance is better than ac servo
