Unimotor fm is a high performance brushless AC
servo motor range with frames from 075 mm to 250 mm, matched for
use with Control
Techniques servo drives. The ‘fm’ stands for Flexible Motor and
is designed to accommodate a wide range of applications. The motors are
available in seven frame sizes with various mounting arrangements and motor
Unimotor fm provides high-precision
over an extended duration requiring lower acceleration
and deceleration rates. The motor is optimized for high
stability in precision profiling applications including:
Unimotor fm motors are a perfect match to Unidrive M
Digitax ST servo drives.
Unimotor FM allows various feedback devices to be used, as standard an
incremental encoder is fitted as this offers an optimum balance of cost and
performance. SinCos and SLM feedback can be selected for increased
resolution and Resolver feedback is available for increased reliability in
High peak torque values allow smaller motors to be
used where the RMS value is low but the maximum torque is high
A wide selection of ready made cables are
available for quick and easy connection to Control Techniques drives
High inertia versions are available to allow
the motor inertia to be more closely matched to the load inertia for
increased performance and stability.
IP65 environmental protection is standard and
ATEX protection available as an option.
Motor brakes may be integrated within the
motor, a choice of parking brake or high energy dissipation brake is
Flexibility of the Unimotor range always ensure
the best fit for your application, as well as the various physical sizes
and feedback devices available, options extend to the type of
Brushless Servo Motor
Unimotor FM is a range of brushless AC servo motors which support a
winding to suit 200/240V or 400/480V nominal AC drives such as the ,
Unidrive classic, M’Ax and MultiAx range of drives. The range is available
in six frame sizes 055:075:095:115:142 and 190mm, each frame size has a
number of shaft diameter options and can offer various front flange mounting
The 190 frame motor has been increased in variants from 4 (A-D) to 8 (A-H).
The design also conforms to the sealing standard IP65 (when mounted and
Wide torque range
Unimotor fm offers the widest torque range,
