HANDLING
DO NOT lift the servo
motor by holding the
! shaft or connectors.
Care should be taken
when lifting the larger
frame size motors,
CAUTION
which can weigh
as much as 85kg. Use mechanical
assistance where possible. The 190mm
and 250mm frame size motors have
lifting eyes to aid handling.
INSTALLATION
Before you attempt
any installation
operations, please
make sure that the
voltage supply to the
motor is off, and the
DANGER
cables are
High Voltage
disconnected.
During operation the
motor surface
temperature may
exceed 100°C. Ensure
that temperature
sensitive devices do
not touch the motor
CAUTION
The machine runs hot
surface.
Mount the motor on a suitable thermally
conductive surface as this will assist in
reducing the motor body temperature and
allow sufficient space around the motor
for the free circulation of air. Ambient
temperatures of between 0°C and 40°C
are acceptable. If the thermal path via the

MECHANICAL INSTALLATION

Unimotors are manufactured in accordance
with the standards EN60034, EN60072-1
(dimensions and output series for rotating
electrical machines) Type N (Normal class),
ISO1940-1 (balancing to G6.3), ISO8821
(half key convention), and are sealed to
IP65.
Bolt the motor flange to a substantial metal
plate.
Correctly locate the registration spigot.
The motor shaft should be correctly aligned
with the driven load.
Ensure the output key is correctly seated
before mounting keyed components to the
shaft.
If you want to run a keyed motor with no
coupling fitted, then to reduce risk of injury,
remove or tape the output key first.
Do not use a hammer to fit components
to the shaft. This will damage the motor
bearings and the feedback device.
Use a bolt and washer to draw components
onto the motor shaft using the tapped hole
in the end of the shaft.
Remove components using a suitable gear
puller.
During connection care must be taken to
ensure suitable sealing for cable outlets.
The conductor size for the Power cable
should be selected according to the motor
stall current.
Allow sufficient room for access to the
cables and connectors. The minimum cable
