Torque motors


Torque Motors

Torque motors are permanent-magnet direct drive motors that rotate along an axis. They can be used wherever a rotary movement is required and offer numerous advantages over conventional servo drives.

Our torque motors are:

  • Extremely compact,
  • Provide an extremely stiff drive train
  • Eliminate the need for time-consuming mounting procedures 
  • Are virtually maintenance free
  • Can be integrated directly into the machine structure, while the spacious open inner diameter enables wire and cable feedthrough.

QTR-A-65 Series

Peak 0.39 .. 3.67Nm
Continious 0.27 ..  2.32Nm

The QTR-A 65 is the smallest torque motor in the Tecnotion QTR range. This motor is optimized for small and low voltage applications. The 65 Series is available in four motor ‘heights’ or ‘sizes’, a 17, 25, 34 and 60 size motor.

Compact sizing and low voltage support make the 65 mm QTR motor ideal for robotics applications.

The build heights are: QTR-A-65-17 // QTR-A-65-25 // QTR-A-65-34 // QTR-A-65-60

Torque 65 series


QTR-A-78 Series

Peak 0.8 .. 7.5Nm
Continious 0.55 .. 4.75Nm

The QTR-A 78 is the second size available in the Tecnotion QTR range. As with the 65 Series motor, the 78 series motor is optimized for low voltage applications with a small build-space available. The largest QTR-A 78-60 motor offers a peak torque of 7.5Nm.

Small build-space and a large 29 mm inner diameter make the QTR 78 motor a favorite in semiconductor machinery.

The build heights are: QTR-A-78-17 // QTR-A-78-25 // QTR-A-78-34 // QTR-A-78-60

Torque 78 series


QTR-A-105 Series

Peak 1.9..18Nm
Continious 1.4..12Nm

The QTR-A 105 is where the medium-range of Tecnotion QTR motors starts. QTR-A 105 motors are available with a wide range of options such as different winding types and a digital hall sensor. 

Various medical and health care applications benefit from the large inner diameter of the QTR 105 as well as the flat designs, starting at just 17 mm.

The build heights are: QTR-A-105-17 // QTR-A-105-25 // QTR-A-105-34 // QTR-A-105-60

Torque 105 series

QTR-A-133 Series

Peak 3.7..35.3Nm
Continious 2.6..21.9Nm

The QTR-A 133 is the second medium-range QTR motor. It covers the torque range from 2.6 to 21.9Nm. The largest 60 mm high QTR-A-133-60 motor offers a peak torque of over 35.3Nm. Different winding types are available, optimizing Back EMF.

High peak force make the QTR 133 Series ideal for usage in testing equipment.

The build heights are: QTR-A-133-17 // QTR-A-133-25 // QTR-A-133-34 // QTR-A-133-60

QTR-A-160 Series

Peak 6.2..58.3Nm
Continious 4.1..36.3Nm

The QTR-A 160 series is the largest in diameter of the QTR motor range. The smallest motor measures just 17 mm in height, the largest motor excels with a 58.3 Nm peak torque.

Power and size make that the QTR 160 Series motors can often replace large factory machinery. They are the best choice when implementing factory automation to the fullest.

The build heights are: QTR-A-160-17 // QTR-A-160-25 // QTR-A-160-34 // QTR-A-160-60

QTR 160 motor overview

To top things off the entire series comes with completely sealed stators and integrated temperature protection and measurement sensors.


With continuous torque ratings ranging from 0.7 Nm to 40 Nm, these motors can play a pivotal role in increasing the availability and cost-effectiveness of many different applications in industries like:

  • Semiconductor
  • Printing
  • Robotics
  • Machine tooling
