Description

The QTR 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 78-60 motor offers a peak torque of 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.
