  • HT Frameless Direct Drive Torque Motors

Allied Motion's HT family are high torque density frameless direct drive brushless motors offering nine frame diameters and stall torque ranging from 0.008 up to 9.2 Nm (1.0 up to 1277 oz-in). HT torque motors offer a clear aperture hollow-shaft of up to 63.5 mm (2.5 in). All frameless HT models are equipped standard with a Hall commutation switch assembly.

Frameless HT torque motors are designed for direct axis integration in machine applications where component rotor-stator solutions are the better choice over housed motors.

Performance of the standard HT frameless direct drive torque motors is summarized in the table below.

Modified standards and completely custom designs are often provided by Allied Motion to our customers. Contact us to discuss your specific application requirements.
