2.12.3 Power dissipation
Power from the servo motors is dissipated via the motor flange and the surface of the motor. The following factors
are important to ensure optimal heat dissipation:
•
Thermally open installation
•
Free convection
The motor data specified for the nominal operating point apply to a motor installed in a thermally open system. The
dimensions of the flange plates used for the measurement are shown in the table below.
Generally speaking, the larger the flange, the better the heat dissipation.
