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.

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. ## Frequently Bought Together - RATTMMOTOR Nema34 12N.m Closed Loop Hybrid Servo Motor Stepper Motor 12nm 1700oz-in 156mm 6A 2 Phase & HSS86 Servo Driver & 3m Wire CNC Controller Kit for CNC Router Engraving Milling Machine - RATTMMOTOR 400W 70V DC Switching Power Supply,5.7A AC 110V/220V to DC 70V Transformer Switch Power Source Adapter Regulated Converter for LED Strip Light Display,CCTV,CNC Router Machine,Stepper Motor - Nema 34 Stepper Motor Steel Mounting Bracket with Mounting Screws --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.in/products/45948033-12n-m](https://www.desertcart.in/products/45948033-12n-m) --- *Product available on Desertcart India* *Store origin: IN* *Last updated: 2026-08-15*
