Complete solution of ETEL TMB+torque motor selection parameters

In the application fields of high-end CNC machine tools, semiconductor manufacturing, robot joints, and precision turntables, direct drive torque motors are gradually replacing traditional "servo motor+decelerator" solutions due to their advantages of zero backlash, high rigidity, high dynamic response, and low maintenance costs. The TMB+series of ETEL (a Swiss company under the Heidelberg Group) is a well-known frameless torque motor product line in the industry, providing a complete selection spectrum from diameters of 0140mm to 1221mm and peak torque from tens of Newton meters to tens of thousands of Newton meters. This article is based on the official technical data manual, systematically interpreting the model system, core performance parameters, thermal management points, and selection methodology of the TMB+series, to help motion control engineers quickly locate suitable motor specifications.
