The displacement angle is determined by the following relationship:
X = (Z ÷ 2π) × sin(Ta ÷ Th) where:
Z = rotor tooth pitch
Ta = Load torque
Th = Motors rated holding torque
X = Displacement angle.
Therefore if you have a problem with the step angle error of the
loaded motor at rest you can improve this by changing the
“stiffness” of the motor. This is done by increasing the holding
torque of the motor. We can see this effect shown in the figure 5.
Increasing the holding torque for a constant load causes a shift in
the lag angle from Q2 to Q1.
Step Angle Accuracy One reason why the stepper motor has achieved
such popularity as a positioning
device is its accuracy and repeatability.
Typically stepper motors will have a step angle accuracy of 3 – 5%
of one step. This error is also noncumulative from step to step.
The accuracy of the stepper motor is mainly a function of the
mechanical
precision of its parts and assembly. Figure 9 shows a typical plot
of the positional accuracy of a stepper motor.
Step Position Error
The maximum positive or negative position error caused when the
motor has rotated one step from the previous holding position.
Step position error = measured step angle - theoretical angle
Positional Error
The motor is stepped N times from an initial position (N =
360°/step angle) and the angle from the initial position
