ETEL unveiled the newest advancement of their torque motor family, the TMB+ during IMTS 2016. In order to keep up with the high demands of the machine tool market, ETEL has taken its existing TMB line of torque motors and redefined it to increase its overall torque, size selection, and winding options to expand upon an already extensive and well renowned series of direct drive motors.
The TMB+ is fully pin-to-pin compatible with the TMB series but offers an increased performance of up to 22 percent continuous torque and up to 4 percent on top of its already high peak torque. Also the TMB+ has reduced power losses, four different winding options per size and a new 200 mm active length for each diameter, increasing its overall size selection from the TMB. These options help propel ETEL torque motors beyond the competition and pushes towards the goal of making direct drive technology as accessible as possible.
The TMB+ series comes in 62 standard model sizes with four different windings each, allowing the user to get maximum performance depending on how much torque, current, and speed needs is required. TMB+ motors can achieve a peak torque of up to 42,900 Nm and utilize flux weakening to increase it is speed capabilities. It also has the option of coming with ETEL’s IMTHP thermal module which, when coupled with ETEL’s torque motors, enables users to reduce their amount of safety margins while receiving precise and reliable temperature monitoring. ETEL torque motors are compatible with most CNC controllers.
