UM, SL and DM motors are for
400/440V nominal AC drive supply voltage and are the
subject of this UM, SL and DM Unimotor manual.
EZ motors have identical mechanical
construction and feedback options, but support a
different winding to suit 220V nominal AC drives and
are the subject of a separate EZ servo motor manual.
The UM motor has been primarily designed to
operate with the Unidrive.
Feedback options include resolver; or
incremental, sincos single-turn, sincos multi-turn
The SL version is a UM motor fitted with special
electronic feedback that operates with
Control Techniques’ M’Ax and MultiAx drives.
This motor-drive combination offers extremely high
resolution, for superb system speed control. High
resolution is essential for many system applications
where speed and position errors must be miniscule.
The feedback comprises of a special Sincos
electronics, both contained within the standard UM
outline. The encoder has a memory programmed with
all the essential motor characteristics necessary to
automatically set all M’Ax parameters, giving an
instant ‘Plug and Play’ capability.
The DM motor is suitable for use with the
DigitAx drive. The stator connections to U and V
are interchanged to match the DigitAx.
Gearboxes - motor torque can be extended by
a good selection of factory-fitted gearboxes,
available to order in a wide variety of options.
Forced air-cooling - customer-fitted fan
blown boxes specially designed to fit the range of
motors, can directly enhance motor performance. (Not
suitable for SL).
Custom specials - a range of special
adaptations e.g. shaft or feedback type are already
designed and may be available where quantities
Cable assemblies - ready made power and
signal cables in lengths of 2-100 meters to connect
motors to the appropriate drive.
