TMM TORQUE MOTORS

After decades of worldwide presence in the machine tool industry with leading edge Torque Motors, ETEL is presenting the new TMB+ motor. TMB+ is an evolution of the renowned TMB Torque Motor that provides a combination of increased performance and new features while maintaining the interfaces of existing motors. In fact, the torque density of TMB+ is increased by up to 20% while keeping the exact same footprint and reducing the power losses by up to 30%. Speed range is also significantly extended. TMB+ is enabling enhanced machine performance and allowing new process to be achieved into existing machines without any design change efforts. With its outstanding performance level, TMB+ will give access to direct drive technology to more applications while keeping quality and reliability at their highest level and reducing cost of ownership. All TMB+ variants are available with an optional cooling jacket. It consists of a precisely mounted metal jacket that ensures water tightness and guarantee exact same motor performance than with the conventional “open cooling” mounting. There are two different cooling jacket types to fit any machine design: radial or axial water inlet / outlet. Characteristics - More than 60 standard sizes available - Active length up to 200 mm - Four different windings per diameter - Open or closed cooling variants - Nickel coating on stator and rotor - Water cooling channels - 600 VDC bus voltage - Very high continuous torque density - High peak torque - Low torque ripple - Compatible with IMTHP module for accurate thermal control Main specifications - External diameter up to 1'290 mm - Large hollow shaft up to 1'070 mm - Peak torque up to 42'900 Nm - Speed up to 4'590 rpm Refer to the corresponding specifications and catalog or ask for the torque motors handbook for more information.

The TMK torque motor range is a unique design redefining the working range of torque motors in the industry. The advanced electromagnetic design of TMK motors allows them to reach speed levels that were totally unsuspected for torque motors. The TMK maximum speed range can reach 8 times the speed of similar size conventional torque motors. In addition, the continuous and peak torque is larger than similar size torque motors. As such, TMK is a unique revolutionary design that drastically changes the definition of “high speed” in the torque motor world. Characteristics - 24 standard models available - More torque and more speed compared to classical torque motors - High motor robustness (fully encapsulated magnets) - Very high peak torque - TMK stator (up to Ø530 mm) compatible with the mechanical interface of the TMB series - Water cooling channels - 600 VDC bus voltage - Very high peak torque - Continuous torque increased by up to 30% vs TMB - Up to 8 times speed increase vs TMB - Field weakening compliant - Compatible with IMTHP module for accurate thermal control - Low torque ripple Main specifications - External diameter up to 1'050 mm - Large hollow shaft up to 800 mm - Peak torque up to 20'800 Nm - Speed up to 5'450 rpm Refer to the corresponding specifications and catalog or ask for the torque motors handbook for more information.

The TML torque motor is a low weight and low cost version of the famous TMB motor. This motor range is perfectly suited for applications that require the dynamic performance level of a direct drive torque motor while being less demanding in continuous torque. The TML is used in applications where water cooling is not requested. TML motors are designed with specific fixing lugs to be easily assembled into the final machine structure. Characteristics - 25 standard models available - Low cost - No water cooling option - 600 VDC bus voltage - Very high peak torque - Compatible with IMTHP module for accurate thermal control - Low torque ripple Main specifications - External diameters up to 581 mm - Large hollow shaft up to 420 mm - Peak torque up to 4'990 Nm - Speed up to 1'000 rpm Refer to the corresponding specifications and catalog or ask for the torque motors handbook for more information.
