For the first time at IMTS, ETEL will unveil the newest advancement of their torque motor family, the TMB+. 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.
Continuing its reputation of being a worldwide leader in direct drive technology, ETEL continuously strives to deliver the most top-of-the-line product on the market and the TMB+ is a further example of this. The TMB+ is fully pin-to-pin compatible with the TMB series but offers an increased performance of up to 22% continuous torque and up to 4% on top of it is already high peak torque. Also the TMB+ has reduced power losses, four different winding options per size and a new 200mm 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.
The TMB+ series is designed specifically for direct drive applications and offers the following advantages over transmission-based devices:
- Fewer parts requiring lower overall costs
- Stable performance along the machine’s lifetime due to zero maintenance being required
- No backlash, allowing for better accuracy and repeatability
- Smooth, precise, and efficient motions
- Compact design
ETEL takes pride in their policy of full disclosure about their motor performance. It is standard for all data sheets to list its specifications at its highest operating temperature so that no special design is required to reach them, ensuring that the user is able to utilize every bit of power that the motor is capable of producing.
