Product Description

Kollmorgen has a long history of manufacturing top quality industrial grade motion components and systems. Their products can be found in industries such as automotive, defense, aeronautical, medical, and robotics. Kollmorgen’s product portfolio includes servo drives, digital amplifiers, frameless motors, embedded PCs, and linear positioners. The TBM series is one of the products that the company specializes in.

The TBM series are frameless DC motors that are known for their performance, durability, minimal maintenance, and efficiency. The TBM-12941-B is part of the TBM series. This motor has an armature outer diameter of 129 inches and a stack length of 41 inches. The TBM-12941-B weighs 3.17 Kg and has an inertia of 7.21E-04 Kgm². The maximum static friction for this unit is 0.346 Nm with peak-to-peak cogging friction of 0.216 Nm. This motor is RoHS compliant and has laser marked armatures. The low cogging design and banded rotors contribute to the smooth and efficient performance of the TBM-12941-B. It also has a rotor hub geometry for easy installation.

This frameless motor has stainless steel yokes for maximum corrosion protection and has pre-aligned/factory installed latching hall effects. To avoid overheating, it must be installed and mounted with a heatsink. This frameless motor has 12 poles and comes with customer specified bolt hole circumferential pattern. Generally, this module comes in Black/White/Red lead colors, but they can be changed to other colors as specified by the customers. The KTY or PTC type thermal sensors can be embedded in the motor slot. The TBM-12941-B has a type ‘B’ winding. The inductance for this motor is 0.68 mH. The peak torque can be limited by the lead wire gauge.
