Specific stepper motor parameters

1. Step angle – represents angular displacement of the rotor for one control impulse;

1. Maximum no load start frequency – represents the maximum control impulse frequency at which the unloaded 
2. Best stepper motor can start, stop or reverse without losing steps;
3. Limit start frequency – represents the maximum impulse frequency at which the motor can start without losing steps, when a given moment of inertia and torque load are presented at the shaft;
4. Pull-in torque – represents maximum torque load at the shaft, at which the motor can start without losing steps;
5. Maximum no load frequency – represents the maximum impulse frequency that the motor can follow without losing synchronization;
6. Maximum frequency – maximum frequency of impulses at which a motor keeps its timing for given torque load and inertia;
7. Pull-out torque – maximum torque that can be maintained by the motor at a certain speed, without losing steps;
8. Angular speed – is calculated as a product between the stepping angle and the control frequency;
9. Detent torque – represents the value of the holding torque presented by at the motor shaft when it is not electrically energized.
