3.4 Handling of motors
Assembling motor axis and transmission element
Couplings, pulley, and motor pinion (transmission elements) must be assembled
using adequate tools. Otherwise the motor shaft can be distorted which damages
the resolver. Never use a hammer, as this will damage the equipment.
CAUTION
When fitting the transmission element, make sure not to use high force or other
methods that can damage the transmission element, shaft, resolver, or connection
box.
The motor axis should be fitted using a press tool or a method with a dolly. Use
heating if required.
The maximum allowed press force depends on the assembly method. See the
following figures and tables.
Note
Grease the shaft after assembly to avoid oxidation.
Assembly with press tool
Assembly using a press tool with dolly is the best method. The tool can be fitted
on the motor shaft as shown in the following figure.
Note
This method is not applicable for MU 100 since it does not have a flange on the
motor shaft.
