High torque multiple gear ratio double stacked 15mm stepper motor
with worm gearbox
Description:
This is 15mm diameter double stacked motor with worm gearbox.
This motor is a double stacked motor.
It is two 15mm stepper motors combined together to provide motor
torque.
The efficiency of this motor is about 80%, and a double stacked
motor has about 1.8 times of torque compared to a single 15mm
motor.
We have different gear ratios for you to choose, from 21:1 to
1030:1

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
