Torque Motors
High torque density frameless
brushless motors
Continuous stall torque from
0.008 Nm (1.1 oz-in) through 9
Nm (1277 oz-in)
Continuous power ratings from
7 W through 665 W.
Allied Motion’s HT (High Torque)
series of frameless brushless torque
motors are available in nine diameters
from 19.3 mm (0.76 in) up to 127 mm
(5 in). The HT0080x series is featured in
this datasheet.
Each frame size is available in up to six
stack lengths, enabling designers to
choose from a number of performance
levels in each frame size.
Continuous stall torque ratings range
from 0.008 Nm (1.1 oz-in) up to 9 Nm
(1277 oz-in). Winding voltage is 24 V
and 100 V for the largest two frame
sizes. Integral Hall effect commutation
sensors are provided as standard, and
require no setup on the part of the user.
The standard HT series motors are
especially well suited for direct
integration into applications that
demand high power density motors with
minimum size, weight, and inertia. Non-
standard models of the HT series are
also available in stator diameters up to
239 mm (9.42 in).
Typical applications for the HT series
are semiconductor manufacturing
equipment, medical systems, including
life support, robotic systems, laser
sighting and control, and cryogenic
cooling pumps, to name a few.
