Various gear ratio 20mm 18° step angle stepper motor with gearbox

Description:

This is a 20mm stepper motor fitted with a gearbox.
The stepping angle of a single 20mm motor is 18°/step.
With the gearbox, the step angle of the motor is smaller and the torque of the motor is much improved. (depending on gear ratio)
Customers can choose different gear ratios according to their own requirements.
In addition, other parameters such as motor resistance/cable length/connector type, output shaft length, shape, etc. can be customized.
Motor starting gear: M 0.25 Z14 L 1.5, the height from the upper end face of the shaft to the motor end cover is 3.8~4.2
The output torque is the motor torque and the reduction ratio multiplied by the efficiency. The efficiency is related to the number of gear stages. The reference is as follows: 3/4 stage, 85%, and each subsequent stage is multiplied by a 0.9

Application of stepper motors:

Stepper motors are used for precise control, widely used on medical equipment, 3D printer, industrial precise control, automation equipment, etc.

Stepper motors can be used in any mechanisms requirement precise conrtol and rotational/linear movement.


Advantage of stepper motors:

Stepper motor can reach precise control even without close-loop encoders / without feed back system, also they do not have electrical brushed. Thus there is no electromagnetic interference and electrical sparks issues. In some cases, they can replace DC brushed motors/ brushless motors.

Stepper motors are easy to control with drivers, and this feature establish its important position in the field of precise control.

1. Precise control achievable, programmable

2. Without electromagnetic interference & electrical sparks

3. Small size

4. Reasonable price

5. Low noise

6. Long service life


Stepper motors are widely used among all industries.
