2.4.6 Measures to suppress temperature increase of the servo motor

 When installing the servo motor, pay attention to the cooling conditions (such as size of the
2
heat sink) provided in the specifications of each servo motor type.
 The heat generated during motor operation is dissipated to the heat sink through the motor
mounting surface. Therefore, if the surface area of the heat sink is too small, the
temperature of the servo motor may increase abnormally.
 If it is difficult to apply large heat sinks in the operating environment or if the ambient air
temperature or altitude exceeds the given specifications, take the following measures:
(1)
(2)
(3)
Important: do not place a gasket or other insulating materials between the servo motor and heat
2-14
Reduce the full-load rating of the servo motor. For more details, refer to the
specifications of each servo motor type. When selecting servo motors, consider
motors with the power capacity 1 to 2 levels higher.
Reduce the acceleration and deceleration of the work cycle to lower the motor load.
Apply external forced air cooling to the servo motor by using cooling fans or other
methods.
sink, as it may cause motor temperature increase and poor noise immunity, and result
in malfunction.
