The AKM21G-BNM22-00 from Kollmorgen is a high-performance member of the AKM Synchronous Servo Motors series designed for demanding industrial automation environments. This robust 3-phase motor operates at an input voltage of 230 V and delivers a rated load of 2 HP, ensuring reliable power for precision tasks. With a standstill torque of 0.50 Nm and a peak torque of 1.51 Nm, the AKM21G-BNM22-00 provides both steady-state control and dynamic overload capacity. The motor’s rotor moment of inertia of 0.11 kgcm² supports rapid acceleration and deceleration cycles without compromising stability. Compact yet powerful, this servo solution balances torque density and minimal footprint for space-constrained installations.

Technical performance is anchored by the Frequency Inverter Drive architecture, which delivers smooth current modulation across all 3-Phase windings. The motor’s winding inductance of 2.18 mH and torque constant of 0.10 Nm/A optimize responsiveness and energy efficiency during transient loads. High-resolution positioning is achieved via the integrated Comcoder feedback system, ensuring sub-millimeter accuracy in motion control loops. The smooth shaft and NEMA flange configuration simplify mechanical integration, while the frame dimension of 58 mm provides a standardized envelope for mounting and alignment. With a rotor length index of 1, the design maintains low inertia without sacrificing torque output.

Operational reliability is elevated by the inclusion of a 24V holding brake, which secures the load instantly upon power loss or command hold. The winding designation G and standard customization level guarantee reproducible manufacturing quality and streamlined maintenance. Thermal stability is inherent in the motor’s robust construction, enabling continuous operation at rated current while minimizing temperature rise. Engineers benefit from the motor’s optimized shaft detail, which resists axial and radial stresses, reducing wear and extending bearing life. The combination of precise feedback, low friction, and balanced rotor dynamics ensures consistently smooth and repeatable performance in stop-and-go processes.

Integration into complex automation systems is seamless thanks to the AKM21G-BNM22-00’s compatibility with Kollmorgen drive controllers and common industry protocols. The servo motor’s standardized NEMA mounting and electrical interface simplify mechanical assembly and wiring tasks on the plant floor. Its high torque-to-inertia ratio and reliable Comcoder feedback make it ideal for applications such as robotic manipulators, conveyor indexing, packaging machinery, and CNC tooling. By combining rugged industrial grade components with flexible drive compatibility, the AKM21G-BNM22-00 offers a versatile solution for precision-driven manufacturing processes.

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!
