Allowed loads for WECM (IEC 80) motors, according maximum speed:
Direction
Axial*
Radial**
Notes:
* Axial max. load (radial zero).
** Radial max load (axial zero).
1 - All belt loads are considered to act in vertically downward direction.
2 - Overhung loads include belt tension and weight of sheave.
3 - Overhung load limits do not include any effect of unbalanced magnetic pull.
Only remove the corrosion protection grease from the shaft end and flange immediately before the
motor installation.
Unless specified otherwise in the purchase order, WEG motors are dynamically balanced with "half
key" and without load (uncoupled).
The driving elements, such as pulleys, couplings, etc., must be balanced with "half key" before they
are mounted on the shaft of the motors.
ATTENTION!
 The air used for cooling the motor must be at ambient temperature, limited to the
temperature indicated on the motor nameplate;
 Take the required measures in order to ensure the degree of protection indicated on
the motor nameplate:
Unused cable inlet holes in the terminal boxes must be properly closed with
blanking plugs;
The cable entries used must be fitted with components, such as, cable glands
and conduits;
Components supplied loose (for example, terminal boxes mounted separately)
must be properly closed and sealed;
Fixing elements mounted in the threaded through holes in the motor enclosure
(for example, the flange) must be properly sealed.
 For flying leads motors, do not push the overlength of leads into the motor in order to
prevent that they touch the rotor.
