Description: Stepper motors are great motors for position control. They can be found in desktop printers, plotters, 3d printers, CNC milling machines, and anything else requiring precise position control. Steppers are a special segment of brushless motors. They are purposely built for high-holding torque. This high-holding torque gives the user the ability to incrementally “step” to the next position. This results in a simple positioning system that doesn’t require an encoder. This makes stepper motor controllers very simple to build and use.

These stepper motors, in particular, are used with the Shapoko CNC machine and offer 125 of torque and 200 steps per revolution. Additionally, each motor has been equipped with extra long 600mm AWG22 wires, making them ideal for CNC applications.

Note: This is a Bipolar stepper.

    NEMA 23 Mounting Holes

    To clarify, the 125 Stepper Motor uses the NEMA 23 mounting holes. The motor size of this stepper motor is slightly smaller than what you would expect for a NEMA 23 motor size width and length. Try looking at the datasheet for more information about this motor’s dimensions.

  • Good Morning

    What is the max supply voltage for this motor?

    Could I use 12V or 24V?

    And what is the current for power supply I could use?

    Thank you

  • Found a torque curve datasheet for this motor.

    It’t for a different brand but same model, and several others within the series.

    At 600 pulses per second torque is about 0.83 Nm and at 2100 pps about 0.72 Nm

    • Thanks for the resource, when you say RPM I believe you’re actually referring to PPS. With 200 steps per revolution 600PPS actually corresponds to 180RPM, and 2100PPS corresponds to 630RPM

      • I’m glad you spotted that! Thanks! I completely missed the PPS rather than RPM on the data sheet, so used to working with RPM torque curves. I’ll have to edit my post. :D

  • How can I connect this drive shaft to something without welding tools?

    • Look for couplers online. “Stepper motor couplers” should do the trick. Most motor shafts will not be completely circular but have a little portion that’s flat. Couplers are cylinders designed to slot into that shaft, with a hole at the other end to connect it to another shaft of you choosing. If my description doesn’t make sense, check it out online, here’s an example of one -

      • Thanks for the link, but this motor shaft is actually completely circular.. I’m not sure why the manufacturer would make it this way, but I’m thinking I might have to drill a small hole so that I can use a set screw or something.

  • what drive that i can use it with this motor? and what the power supply?

  • Can I use the “Big Easy Driver” to control this stepper motor? ( )

  • I was just looking at this product, saw it said it was unipolar, saw Pokey’s comment then refreshed the page and the Wiki link and wording was changed to Bipolar. Nice!

  • Wouldn’t this be a bipolar stepper since it has only four leads?

It’s working perfectly

I am very happy to owned product like this motor

Strong and precise!

This stepper motor is a great buy. Very sturdy/solid build in a compact design. Works as described and I have no complaints about it.
