Tecnotion QTL 210, 230, 385 and 485 Torque Motors
Tecnotion QTL 210, 230, 385 and 485 are frameless, three-phase synchronous torque motors for direct integration into a machine axis. They share an open-center architecture but differ substantially in diameter, torque, inertia and cooling arrangement. The 230, 385 and 485 include a cooling ring that the machine housing must complete; these are motor components rather than complete supported rotary axes.
Key Specifications
Architecture | Frameless three-phase synchronous motor; separate stator and rotor; external drive, feedback, bearings and housing required |
QTL-A-210-65 / -85 / -105 | Continuous 65 / 103 / 142 Nm; stall 46 / 73 / 100 Nm; peak 140 / 211 / 281 Nm; Ultimate 173 / 259 / 346 Nm |
QTL-A-230-65 / -85 / -105 | Continuous 67 / 107 / 147 Nm; stall 48 / 76 / 104 Nm; peak 140 / 211 / 281 Nm; Ultimate 173 / 259 / 346 Nm |
QTL-A-385-85 / -105 | Continuous 407 / 560 Nm; stall 288 / 396 Nm; peak 833 / 1111 Nm; Ultimate 1026 / 1368 Nm |
QTL-A-485-85 / -105 | Continuous 659 / 907 Nm; stall 466 / 642 Nm; peak 1342 / 1789 Nm; Ultimate 1651 / 2202 Nm |
Stator OD / rotor ID | 210: 210 / 140 mm; 230: 230 / 140 mm; 385: 385 / 280 mm; 485: 485 / 366 mm |
Maximum voltage rating | 480 VAC RMS phase-to-phase (680 VDC in the catalog); this is a maximum rating, not a required supply setpoint |
Thermal rating conditions | Continuous and stall data use 100°C coils and a 20°C mounting surface; catalog specifications ±10% |
Transient rating definitions | Peak: 6 K/s temperature rise; Ultimate: 20 K/s; both stated with magnets at 25°C |
Cooling-ring models | 230, 385 and 485; housing, seals, coolant connections and external circulation remain integration work |
Temperature sensors | Three PTC 1 kΩ and three Pt1000 elements listed in the QTL tables |

Applications and Industries
Tecnotion identifies rotary indexing tables, printing machinery, materials handling and related industrial machinery as QTL applications. Consider the motor for those mechanisms where the large bore and direct-drive topology fit the motion cycle. The machine still needs validated bearings, feedback, thermal management, guarding and control; these are selection possibilities rather than claimed ATC installations.
Industrial automation
Review Summary
The QTL family is a strong candidate for an OEM rotary table, printing axis or handling mechanism where direct drive and a large center opening justify custom mechanical and thermal engineering. Choose the exact diameter and height against moving torque, holding torque and the full speed cycle. A 2202 Nm Ultimate headline does not describe continuous output, and a cooling ring does not constitute an installed cooling system.
