Description
This tiny stepper motor is the same quality and step-size as the big NEMA-17's we stock, but so cute so it will work with compact CNC builds. This 4-wire bipolar stepper has 1.8° per step for smooth motion and a nice holding torque. The motor was specified to have a max current of 600mA so that it could be driven easily with an Adafruit motor shield for Arduino, Motor Bonnet for Raspberry Pi or our Feather Motor controller & and a wall adapter or lead-acid battery. It's rated for 3.9V, if you have a stepper driver with current limiting, use that to keep the power down. If you have a non-current-limiting driver such as the motor shield/hat/feather we found 5V DC power worked well to power the stepper controller.
The cable has ready-to-go wires - the drive-shaft does not have a D cut in it, but you can clamp to it pretty easily. We drove it with an Adafruit motor shield for Arduino and it hummed along nicely at 50 RPM.Please note: the wire colors on these motors may vary!
If you have a motor with Green/Black/Yellow/Red color wires, to connect to our shield/hat/featherwing, put the wires in this order: Black, Red, skip ground if there is one, Green, Yellow.
If you have a motor with Yellow/Red/Orange/Blue color wires, to connect to our shield/hat/featherwing, put the wires in this order: Red, Blue, skip ground if there is one, Yellow, Orange.
