Brushless Torque Motors
High torque density frameless
brushless motors
Continuous stall torque fro m
0.007 Nm (1.0 oz-in) through 9
Nm (1277 oz-in)
Continuous powe r 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). Each frame series is available in
up to six stack lengths, enabling
designers to choose from a number of
performances in each series.
Continuous stall torque ratings range
from 0.007 Nm (1.0 oz-in) up to 9 Nm
(1277 oz-i n). Wi nding 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 applicatio ns 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.
