The Beckhoff AM8121-3F21-0000 motor, part of the AM Synchronous Servo Motors series by Beckhoff, is a compact, high‑precision drive designed for light‑duty industrial automation tasks. As a permanent magnet‑excited three‑phase synchronous motor, it features a rated speed of 3000 min⁻¹ and a standstill torque of 0.50 Nm, ensuring stable performance during dynamic operations. With a peak torque of 2 Nm, this servo motor handles short bursts of high load, making it ideal for applications such as precise positioning in assembly systems or small conveyor drives where space is at a premium.

In terms of technical specifications, the AM8121-3F21-0000 delivers a rated power of 0.16 kW and operates on a nominal voltage of 24…48 V DC, optimizing energy efficiency in low‑voltage environments. It draws a standstill current of 4.0 A and can manage a peak current of 17.0 A, providing a broad operational envelope for varying load conditions. The torque constant of 0.13 Nm/A enables precise torque control, while the rotor moment of inertia of 0.134 kgcm² ensures rapid acceleration and deceleration with minimal overshoot. Convection cooling simplifies installation by eliminating external cooling hardware, improving reliability in confined spaces.

Additional features of the AM8121-3F21-0000 include integrated feedback via a resolver and a single‑turn absolute encoder for high‑resolution position control. Connectivity is secured through itec® plug technology, offering robust electrical contact even in vibration-prone environments. Rated for ambient temperatures from +5…+40 °C, this servo motor maintains consistent performance across typical industrial climates. By combining compact design, efficient power utilization, and precise feedback, the Beckhoff AM8121-3F21-0000 enhances throughput, reduces downtime, and delivers exceptional stability in modern automation systems.

Testimonials

We used Servo Supplier to refurbish old drives and buy reconditioned parts. We received great and timely service at a fair price. I recommend them to anyone who has aging equipment and can't find support from their OEMs. Highly recommend.

Bostik Inc.

WE absolutely LOVE Servo Supplier. They are quick, efficient and friendly. Honest too, which is huge in our industry. We deal with many different companies, and these guys are tops in our humble opinion. There has never been an issue with delivery, no warranties, no hidden fees, no surprises. Just what you want in the manufacturing business. Smooth, and we love smooth.

Technomech Inc

First-time customer. The ordering process was completely seamless. The part that we ordered was at our business within 2 days. Which was excellent! We had a piece of equipment down for a little more than 48 hours. Could have been a lot longer had we purchased from one of our normal suppliers.

Steve T. from NF&M International

I found these guys online and needed a somewhat obscure part quickly, and they delivered! Very quick process from the time I requested a quote to the shipping of my items. Great work Servo Supplier team!

FlexPac

Servo Supplier is my go to place for obsolete parts. They always seem to find them and the price is usually good. Any time I have questions they respond very quickly and professionally. I highly recommend them!

Middlesex General Industries

They were very quick to get the drive we needed shipped out to us. They were also very quick to respond and help with some pictures of information on the unit we ordered to ensure we received the right part.

Justin Ball from Miba

Understood our situation, and worked to help us get it solved. Very responsive, and stepped out to keep me informed until the product arrived. Exactly as described, and promised.

Brian Tomlin

This company was fantastic to work with! Very patient with us to make sure we were getting what we needed and extremely quick shipping. Would definitely purchase from them again and again!

Carla Morgan

We asked for a fast turn around and Wake was up to the task!
