Exact step angle | |
| This motor is basically a 48 step per revolution stepper motor driving a complicated planetary gearbox. After disassembly I determined what the full step angle was. The spec says the gear ratio was 35.4/1 but this is not quite correct. I found the gear box gear ratio was 35.45454545454/1 or exactly 390/11. 360 deg * 11 / 390 * 48 degrees per step. Or approximately: 360 / 1701.81818181818 = 0.21153846153846 degrees per step. Not the .2118 degrees per step as in the data sheet. Duane | ||

| This motor has a complicated planetary gearbox. After dis-assembly I found the full step angle was exactly: 360 * 11 / 18720 degrees per step Or approximately: 360 / 1701.81818181818 = 0.21153846153846 degrees per step Not the .2118 degrees per step as in the data sheet. Duane | ||

Exact step angle/ | |
| Due to the fairly complicated planetary gear reduction the exact step angle is not .2115 degrees per step but is: 360/18720*11 degrees per step. This is about: 0.21153846153846 degrees. | ||
