Which start/stop frequency is possible or advisable?
Support » FAQ » Stepper motors
The max. possible start/stop frequency depends on the frictional load or frictional torque but principally on the inert external masses and is specified as fs at no-load operation of the motor in the torque characteristics.
If a straight line is placed between fs and the max. torque, in this approach the possible start/stop speed can found very roughly at the intersection point of the torque and straight line where the acceleration torque Ma = J * a to the frictional torque must be added.
The recording of actual start/stop characteristics can only be incorporated through elaborate measurement results with different external inertial masses, which are then entered as a plurality of characteristics in the torque characteristics as parameters. As, on the other hand, the exact moments of inertia at the beginning of the project are often not yet available, we can determine the possible start frequencies experimentally in our laboratory with different inertial masses.
