    How to choose a geared stepper motor?

    • Selecting a geared stepper motor will result in increasing the output torque and decreasing the speed. Simply, the Gearbox Output Speed is:
      Geared Stepper Motor Speed
    • The gearbox output torque will depending on many factors, it can be calculated by:
      Geared Stepper Motor Torque
    • The Gearbox Step Angle can be determined by:
      Geared Stepper Motor Step Angle
    • When choosing a stepper motor with a gearbox, keep in mind that the gearbox Max Permissible Torque, beyond which the gearbox could become damaged.
