Please help me if i'm interpreting the following datasheet of the stepping motor correctly..
**broken link removed**
Rotor step angle : 18 degree
Gear ratio : 1/36
Step size degree in full step mode : 0.5 degree
Step size degree with 6 micro steps : 0.083 degree
Does the "rotor step angle" mean "full step"?
If we call,
Number of rotor teeth : N
Numbe of phases: m
So, based on the formula:
step angle = 360 / (Nxm)
Here m = 2
step angle = 18
--> N = 360/ (18x2) = 10 . Is this correct?
The "Step size degree in full step mode" means the fullstep after going through the gear ratio? As i found that
0.5 degree = 18 degree/36.
And the microstep part, does it mean that if i decompose 1 fullstep into 6 microsteps, i would get 0.083 per microstep? As i can see that
0.083 = 0.5/6
But how can i relate this to the number of levels of the sine & cosine voltages (or resolution) generated for microstepping?
