Microstepping drives, like Applied Motion’s ST, STR and STAC drives, nullify the smoothness benefit of 0.9 degree step motors because these drives are capable of creating equal smoothness with 1.8 degree motors. However in some applications microstepping is not available, such as when a very basic full or half step drive is used, and for these applications a good way to gain smoothness is to use a 0.9 degree motor.
These new motors offer the same great performance and price as our other step motors. They come in NEMA frame sizes 14, 17 and 23. Please visit the 0.9 degree motor page to learn more.
