This is a 20mm bipolar stepper motor with 4 cables (2 phases)
There is a gearbox in the motor and gear ratio is 85:1.
If customers need unipolar motor with 5 cable, we are able to customized it and change coil winding of the motor.
Coil resistance is 40Ω/phase, and this motor’s rated voltage is 5V DC.
If customers require higher rated voltage, we can adjust coil winding and increase its resistance.
The gears inside gearbox are POM plastic gears, we can also make it metal for higher torque since metallic gears have higher strength.
