Before answering this question, let's understand what are stepper motors and gear motors?

Stepper motors

The stepper motor is an open-loop control element stepper motor that converts electrical pulse signals into angular displacement or linear displacement. In the case of non-overload, the speed and stop position of the motor only depend on the frequency and pulse number of the pulse signal, and are not affected by the load change. When the stepper driver receives a pulse signal, it drives the stepper motor to rotate a fixed angle in the set direction, which is called "step angle", and its rotation runs step by step at a fixed angle. The angular displacement can be controlled by controlling the number of pulses, so as to achieve the purpose of accurate positioning; at the same time, the speed and acceleration of the motor rotation can be controlled by controlling the pulse frequency, so as to achieve the purpose of speed regulation.

Gear motor

The geared motor is composed of a reducer (gearbox) + a motor. The motor provides high speed, but the torque is small and the inertia is large. The function of the reducer is to reduce the speed, increase the torque, and reduce the inertia to reach the ideal speed and torque. For example, common electric curtains and electric rolling gates use geared motors with slow speed and large torque.

The difference between stepper motors and gear motors

Simply put, the stepper motors can be controlled at a fixed length and a fixed speed. For example, the speed of the workbench can be set freely when the workbench moves 1 meter. Common application cases include the stepper motor of the workbench of a milling machine.

The difference between the two is:

The stepper motors can be fixed speed and timing (how long you want to go and how fast you can turn); the speed of the reducer is determined by the reduction ratio, and the speed cannot be adjusted;

But the torque of the stepping motor is small, and the torque of the geared motor is large.
