ETEL is renewing its torque motor product range by adding a new motor type, the TMB+. 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. TMB+ has been unveiled during the IMTS 2016 machine tool exhibition in Chicago, IL, USA, in September.
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.
