ETEL has unveiled 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 its 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% continuous torque and up to 4% on top of it is already high peak torque. The TMB+ also 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.
The TMB+ series comes in 62 standard model sizes with four different windings each, allowing the user to get maximum performance depending on the torque, current, and speed requirements. TMB+ motors can achieve a peak torque of up to 42,900 Nm and use flux weakening to increase its speed capabilities. It also has the option of coming with ETEL’s IMTHP thermal module which, when coupled with ETEL’s torque motors, lets users 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 these 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
