The B-402-B-A3, produced by industrial automation leader Kollmorgen, is a highly efficient, low inertia servo motor designed for high acceleration rates. Its power capacity is 2.2 kW, and it reaches maximum speeds of 3000 rpm. Uniquely, this model can be fitted with front-mounted gearheads and an optional fail-safe brake, which provides 8 Nm of torque for emergency braking or static parking. Significant for its compact design, the B-402-B-A3 maintains a high torque-to-volume ratio and has a continuous torque of 7.4 Nm. Compliant with IP 65 and IP 67 sealing standards, the motor can function while immersed up to six feet underwater for 30 minutes. Brushless resolver feedback is shielded by the motor housing, while the explosion-proof design enables safe use in hazardous environments. Additional attributes include a DC tachometer, a 0.6% average to peak voltage ripple for smooth low-speed motion, and class H armature insulation for operation up to 180 ᵒC.

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!

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.
