HT family are high torque density frameless brushless motors offering nine frame diameters and stall torque ranging from 0.008 up to 4.4 Nm (1.13 up to 623 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.
