4-1 Installation Conditions
Radiator Plate Installation Conditions
When you mount a Servomotor onto a small device, be sure to provide enough radiation space
on the mounting area. Otherwise the Servomotor temperature rises too high to break. One of the
preventive measures is to install a radiator plate between the motor attachment area and the
motor flange. (See below) Refer to the "Servomotor Specifications" (P.3-33) for the radiator plate
specifications.
The temperature rise differs by the mounting part materials and the installation environment.
4
Check the actual rise by using a real Servomotor.
Depending on the environment, such as when the Servomotor is installed near a heating element,
the Servomotor temperature may rise significantly. In this case, take any of the following
measures.
Other Precautions
Take measures to protect the motor shaft from corrosion. The motor shafts are coated with anti-
corrosion oil when shipped, but anti-corrosion oil or grease should also be applied when
connecting the components which apply load to the shaft.
4-5
• Lower the load ratio.
• Review the heat radiation conditions of the Servomotor.
• Install a cooling fan and apply forced air cooling to the Servomotor.
Do not apply the commercial power supply
directly to the motor. Failure to follow this
guideline may result in fire occurring.
Never repair the product by disassembling
it. Failure to follow this guideline may result
in electric shock or injury.
