Review: Great little Motor - I used this in a fully automated durability test, at work, where it ran a 6" butterfly valve open and closed. A PLC was used to automate the test. To drive the butterfly valve, a 90deg gearbox and some shafts were used. The main reason I bought this motor was because it had a Torque vs Frequency graph, which is almost spot on. I used that graph to calculate which planetary gearbox reducer I would need, so, I could get the correct output shaft speed and torque for our test. The torque output was verified through the use of a torque transducer and a data acquisition system. The test was setup to have the motor stall out at a predetermined torque when it reached the end of the butterfly valves travel, 20.7 ft-lbs or 26.5 ft-lbs, dependent upon which portion of the durability test we were at. It was stalled over 10,000 cycles before the test completed. The motor was run like this for about a month and a half. Keep in mind that there was some downtime for maintenance and inspections throughout the test, so it's not like it ran for a month and a half straight. During this time the motor didn't receive any maintenance, just our test specimens. The test also wasn't run over the weekends either. I'm impressed it was able to take that many stalls without any issues. The motor still ran fine at the end of the test. The output shaft was still tight in the housing without any side to side motion. It didn't over heat. Overall, it's a nice cheap durable motor.
Review: A professional CNC stepper motor - Spend extra, get closed loop! Was really easy to install! (I'm not even a professional CNC'er.) I have this motor for about 3 years now. I'm still very satisfied. speed and torq in abundance. Learn to use the switches on the stepper driver to get faster speeds

### ⭐ Works at slow speeds, NOT, NOT a servo
*by A***K on April 15, 2019*

To call this stepper a "servo" is not accurate at all. While it works OK at slow speeds (true servos do not care about speed) if you attempt to move the stepper at more than 3000 PPS it will fault out even under a light load. Probably OK for a CNC mill, but NOT suitable for moderate speed motion control.
