Measures To Suppress Temperature Increase Of The Servo Motor - Delta ASD-A2-0121 Series User Manual

Chapter 2 Installation
If you cannot avoid using the servo motor under the above conditions, please take prevention
measures to avoid dirt and water for the machine.

2.9.6 Measures to Suppress Temperature Increase of the Servo Motor

1. When installing the servo motor, please pay attention to the cooling conditions (such as size of
the heat sink) provided in the specifications of each servo motor type.
2. The servo motor generates heat during operation, and the heat generated by the servo motor
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.
3. If it is difficult to apply large heat sinks in the operating environment or if the ambient air
temperature exceeds the given specifications, please take the following measures:
(1) Reduce servo motor full load rating: for more details, please refer to the specifications of
each servo motor type. When selecting servo motors, consider motors with the power
capacity 1 to 2 levels higher.
(2) Reduce the acceleration and deceleration of the work cycle to lower the motor load.
(3) Apply external forced air cooling to the servo motor using cooling fans or other means.
Important: avoid placing a gasket or other insulating materials between the servo motor and heat sink, as this
may result in motor temperature increase, inferior noise resistance, and motor malfunction.
