Product Description

Kollmorgen has over hundreds of years of expertise in providing innovative solutions in the drive and control niche. Their products can be found in major industries all over the world. The TBM series of frameless motors are one of the leading products by Kollmorgen. These frameless motors are direct drive high torque motors designed to deliver power where space is premium.

The TBM-7631-A is part of the TBM product family. This motor has three stack lengths per frame and has two standard winding options per frame. The TBM-7631-A has a low cogging design and is RoHS compliant. It also has banded rotors and laser marked armatures. This means that the markings remain on the armature regardless of the wear and tear. The TBM-7631-A is designed in such a way so that it has minimized inertia and weight and can still deliver high power. Common applications of this motor are weapon stations, sensor gimbals, UAV propulsions, robotic joints and UAV propulsions.

The TBM-7631-A has a continuous current of 10.9 Arms and a peak current of 36 Arms. The design voltage of this motor is 48 Vrms and has a back EMF of 18 Vrms/kRPM. The inductance of this motor is 0.60 Mh and viscous damping of 1.60E-02. The TBM-7631-A has 12 poles and a weight of 738 grams. This motor can be modified with hollow, keyway, flat, round, or flanged rotor hub geometry. The lead length for the base model is 400 mm. Upon customer request, the lead length can be reduced to as much as 150 mm or increased to as much as 1200 mm. The TBM-7631-A can be fully customized as per customer specifications.
