QTR Torque Motor Series

Tecnotions’ smallest and medium range torque motors offer a range of options. The QTR torque motor series are available with different winding types, flying leads, and an optional digital hall sensor.

The QTR 78 is the second size available in the Tecnotion QTR range. This series offers a continuous torque ranging from 0.57 up to 4.41Nm. The largest QTR 78-60 motor offers a peak torque of over 7.5Nm. To provide maximum flexibility and integration the QTR 78 uses flying leads instead of a power cable.  The build heights of the QTR 78 are: 78-17 // 78-25 // 78-34 // 78-60. Check all advantages and features,  for an explanation of torque motors.

Ultimate torque: 1.22 – 10.85Nm
Peak torque: 0.84 – 7.57 Nm
Continuous torque: 0.57- 4.41 Nm

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

The direct-drive technology of brushless torque motors is an ideal way to enhance the productivity, accuracy, and dynamic performance of applications. This technology lowers costs, shrinks space requirements, and reduces wear and tear. Torque motors eliminate the need for mechanical transmission components such as gearboxes, belts, and speed reducers. This reduces transmission losses and eliminates the cost and maintenance required for additional components. And because there is no contact between the rotor and stator, there is no mechanical wear, meaning less maintenance and longer life.

The advantages of the QTR torque motor series are:

• Ultra-thin design
• Highest torque density in the market
• Low thermal resistance
• Low cogging value, low total harmonic distortion(THD)
• Encapsulated design
• Shielded cable with strain relief
• Low stator and rotor mass
• Large inner diameter

Various applications such as semiconductors, life science, machine tooling, printing, rotary tables, factory automation, and robotics benefit the QTR motor series.
