360/1.8 = 200 full steps × 16 = 3,200 steps/rev. Resolution = 360/3,200 = 0.1125°.

200 × 200 / 60 = 667 pulses per second.
Multiply full steps per revolution by the microstep divisor. Full steps = 360 / step_angle. A 1.8° motor has 200 full steps; at 1/16 microstepping that becomes 3,200 steps per revolution.
| Microstep | 1.8° Motor | 0.9° Motor | Resolution |
|---|---|---|---|
| Full (1x) | 200 | 400 | 1.8° / 0.9° |
| 1/4 | 800 | 1,600 | 0.45° / 0.225° |
| 1/16 | 3,200 | 6,400 | 0.1125° / 0.056° |
| 1/32 | 6,400 | 12,800 | 0.056° / 0.028° |
Back-EMF and driver voltage limit max RPM. As speed increases, back-EMF opposes the supply voltage, reducing current and torque. Higher voltage drivers allow higher max RPM.
Yes. At higher microstepping, each step delivers less holding torque. Full stepping provides 100% torque; 1/16 microstepping typically provides about 10–20% of holding torque per microstep.
Most 3D printers and CNC machines use 1.8° (200 steps/rev). Precision applications like astronomical trackers may use 0.9° (400 steps/rev). Higher resolution increases smoothness but reduces max speed.
