Measures To Suppress Temperature Increase Of The Servo Motor - Delta ASDA-B3 Series User Manual

Installation
3. If the servo motor must be mounted with the shaft end up, do not use it in a machine,
gearbox, or other environment where the servo motor may have contact with oil or water.
2
4. Do not use the servo motor in an environment with cutting fluids. Depending on the type of
cutting fluids, sealing materials, coated colloids, cables, or other components may be
affected or even deteriorated.
5. Do not continuously expose the servo motor to oil mist, water vapor, oil, water, or grease.
If you cannot avoid using the servo motor under the above conditions, take prevention
measures to avoid dirt and water from entering the machine.

2.4.6 Measures to suppress temperature increase of the servo motor

1. When installing the servo motor, pay attention to the cooling conditions (such as size of the
heat sink) provided in the specifications of each servo motor type.
2. The heat generated during the 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.
3. If it is difficult to apply large heat sinks in the operating environment or if the ambient air
temperature or height exceeds the given specifications, take the following measures:

Important: do not place a gasket or other insulating materials between the servo motor and heat
2-12
(2)
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, affect noise immunity, and result in
malfunction.
