20BY45-67 PM permanent magnet 9 Ohm 20mm 18° step angle stepper motor for gearbox
Description:
This 20BY45-67 motor is our 20 mm permanent magnet PM stepper motor.
Motor’s coil resistance is 9Ω/phase, and it’s designed for low driving voltage (around 5V DC).
If customers want to drive the motor at higher voltage, we can adjust coil resistance to match it.
Also there are two M2 screws on motor’s cap, and they are used for fixing with gearbox.
Customers can also use screws to fix this motor on other components.
Connector type is 2.0mm pitch (PHR-4), we can change it into others if customers want to replace it.

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
