Description

Torque QMT-HA 385 series
Maximum efficiency with more torque

At just Ø385, this HA 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.

Torque
  • Ultimate torque: 1115 – 2678 Nm
  • Peak torque: 987 – 2371 Nm
  • Continuous torque: 481 – 1261 Nm
  • The build heights are: 385-90 // 385-110 // 385-130 // 385-160

Applications
Torque direct-drive torque motors are designed for integration in semiconductors, machine tooling, robotics, display applications and the printing industry. The QMT-HA 385 series targets use cases that need high torque density, compact mechanical impact and direct-drive performance.
