Tecnotion QTR torque: more and more flexible

Servotecnica announces a new series of Tecnotion QTR torque motors.

Officially unveiled at SPS IPC Drivers 2017 in Nuremberg, the new 65 and 78 mm motors are now available for applications requiring even more compact systems, but with the same high quality standards of current QTR motors, with which they also share low axial height and high torque density. The special rotor design makes possible the large inner diameter. This makes it possible to use hollow axles, even for the QTR 65 motor.

Four different stator heights are available for each diameter. The small QTR motors therefore suit a wide variety of markets including semiconductor, medical, machine tooling and robotics.
QTR 65 and QTR 78 motors have a brushless design. No mechanical transmission is needed. Torque ranges from 0.3-2.3 Nm continuous for the QTR 65 and 0.6-4.7 Nm continuous for the QTR 78. Speed ranges from 410-6200 rpm at just 48 volts. To provide maximum flexibility and integration the QTR 65 and QTR 78 use flying leads instead of a power cable.
