The QTL 385 and QTL 485 come in two heights, 85 and 105 mm. When using the integrated cooling ring suitable for water cooling a continuous torque range of 407 up to 907 Nm can be achieved. In combination with a very high motor constant, it means that the motor produces a lot of torque without generating a lot of heat. This means that the peak performance is especially impressive, with a range of 1026 up to 2202 Nm it stands high above comparable torque motors in the market. At 480 Vac the maximum speed of the smallest torque motor, QTL385-85, is 231 RPM.

Features such as large inner diameter, strain-relieved cable exit, integrated temperature sensors, high motor constant, low thermal resistance, and low stator and rotor mass differentiate the QTL motors from other torque motors currently available. The very large inner diameter it allows for easy routing of cables or fitting other parts through the rotor. It, therefore, suits a wide variety of markets including rotary indexing tables, printing, material handling, packaging, and laser cutting.
