3.5 Coupling
3.5.1 Preparation
Turn the motor by hand before coupling to detect any possible damage due to handling.
Removeanyprotectionfromtheshaftextension.Draino󰀨anycondensationwhichmayhaveformed
inside the motor by removing the plugs from the drain holes.
3.5.2 Balancing
Rotating machines are balanced in accordance with standard NEMA MG1.
The motors are balanced with ½ key as standard unless otherwise indicated. Any coupling element
(pulley, coupling sleeve, slip-ring, etc.) must therefore be balanced accordingly. To determine the motor
balancing, refer to the nameplate.
The coupling needs to be adapted to the length of the key, or the visible parts protruding from the key
need to be machined. A customized key can be used.
