The QTL 385 series is a family of frameless 3-phase synchronous torque motors designed for high-torque applications. The stator outer diameter is 385 mm, with rotor inner diameter of 280 mm. Stator heights are 85 mm or 105 mm, and lamination stack heights are 60 mm or 80 mm. Maximum phase-to-phase voltage is 680 V ac rms. Continuous torque at 100°C is 407 Nm for the 85 mm variant and 560 Nm for the 105 mm variant. Continuous current is 15.7 A rms and 16.2 A rms respectively. Thermal resistance from coils to mounting surface is 0.039 K/W and 0.029 K/W. Water cooling flow is 9.8 l/min and 13.1 l/min to maintain ∆T=3K. Integrated PTC or Pt1000 temperature sensors are included. The design enables direct integration into rotary systems.
The QTL 385 and QTL485 torque motors supersede the QTL-210 -310 series as the biggest torque motors that Tecnotion has to offer. It has the same efficient and space-saving electromagnetic design scaled up for even higher torque demands. With a big inner diameter, it is very suitable to integrate into an (existing) application in a wide variety of markets like rotary indexing tables, printing machinery, and materials handling.
