Please review the entire listing, and video to understand exactly what you're purchasing.
This listing is for a brand new Nema 23 600oz in stepper motor rated at 3.5A, 1/8 degree, featuring a single 8mm shaft with flat machined into it. These are 4 lead bipolar steppers.
This motor also features an integrated 24v brake which locks into position when the voltage isn't present. This motor is ideal for a heavy Z axis where ball screw transmissions are used causing the axis to lower when the motor has no "holding torque" from the controller being turned off.
They are also ideal for where you want to make sure your steppers never lose position when your controller is off, and the robot's axis are slightly hit, or bumped in high traffic shop environments.
Please review the video overview of mr covering the details of this motor.

Very few CNC systems require more torque than these provide at (600oz/in is 37.5in/lbs)
The brakes torque rating on this motor is 300oz/in (18.75in/lbs)
Motor wiring schematic for the motor, and brake is listed in the schematic above with polarities.
*Due to high demand these units can take up to 5 days to have stock replenished in the event there sold out.
These motors are very powerful considering there torque rating, and provide more than enough holding torque for light to medium grade CNC's.
These can also be used in robotics, and many other applications requiring a great deal of torque with 3.5A. These motors also feature 3.9 inductance rating so they hold their torque much better at higher IPM Speeds.
I encourage you to check my store to compliment these motors with a Gecko G540, shielded motor cables, and power supplies. I will offer the lowest combo pricing online period.
