Advantages:
- The main advantage of stepper drives is accuracy. When current is supplied to the windings, the stepper motor will rotate strictly at a certain angle. The positioning error is within 3 - 5% of the step and this error does not accumulate from step to step.
- The dependence of engine speed on discrete pulses allows you to control the engine without feedback.
- The cost of stepper drives is on average 1.5-2 times cheaper than servos. A stepper drive, as an inexpensive alternative to a servo drive, is best suited for automating individual components and systems where high dynamics are not required.
