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
