The QMT-HA 385 series consists of frameless torque motors with a stator outer diameter of 385 mm and a mounting height ranging from 90 mm to 160 mm. The motors are 3-phase synchronous, with a maximum bus voltage of 680 V dc, and deliver continuous torque between 481 Nm and 1261 Nm depending on variant, with peak torque up to 2371 Nm. The rotor height varies from 51 mm to 121 mm, and rotor inertia ranges from 0.107 kgm² to 0.253 kgm². All variants feature 56 poles, water cooling capability, and integrated PTC130 and Pt1000 temperature sensors. The motor constant ranges from 124.6 (Nm)²/W to 356.0 (Nm)²/W. Thermal resistance from coils to mounting surface ranges from 0.017 K/W to 0.042 K/W. The series is partly approved, with full approval pending.
The QMT-HA 385 series redefines what's possible in the same stator size. Delivering up to 41% more performance, it upgrades your machine with minimal mechanical impact. The HA series distinguished itself with an increased rotor height while keeping the outside of the stator equal. With seamless torque transfer directly to your tooling, energy loss and backlash are eliminated. Lower costs, higher efficiency, and precision that goes beyond industry standards - whether you aim for more productivity or unmatched accuracy.
