Now that we understand "Maximum Holding Torque", we can learn more about some of the other terms we use in our specifications.
Q: What is the difference between "Maximum Torque" and "Permissible Torque" of my geared step motor? (Planetary and harmonic geared types only.)
EXAMPLE ON PAGE 23: http://www.orientalmotor.com/products/p ... es_USA.pdf
Maximum Torque is the maximum torque that can be used for a short time; usually only during acceleration and deceleration. Using geared step motor beyond its "permissible torque" will have detrimental effects on the life of the gearhead.
Permissible Torque is the torque limited by the mechanical strength of the gearhead when operated at a constant speed. For the types excluding planetary and harmonic geared types, the total torque (load torque + acceleration/deceleration torque) should not exceed this value.
