When to use a stepper gear motor

A reduction stepper motor is a stepper motor with a reduction gearbox. The most common purpose is to increase the output torque of the motor without significantly increasing the size of the motor flange, and when selecting the type, the two main parameters of torque and speed should be synthesized first.

Geared motor torque and speed is often determined by the capacity of the gearbox rather than simply based on the motor torque X reduction ratio. Compared to stepper motors, gearboxes are often the weakest link in the domestic manufacturers, gearboxes are often prone to vibration, noise, life and other aspects of the problem.
In addition to the torque there are other reasons to use a reduction stepping motor, for example, through the reduction ratio to let the motor speed to avoid the resonance point of the system; load inertia is too large when the gearbox to let the motor and the load inertia has a reasonable match, to avoid overshooting the load when the load is shut down; through the reduction ratio to reduce the step angle.
