Radiator Plate Installation Conditions
• When connecting to a V-belt or timing belt, consult the manufacturer for belt selection and tension.
• A radial load twice the belt tension will be placed on the motor shaft. Do not allow a radial load
• Set up a movable pulley between the motor shaft and the load shaft so that the belt tension can
• The protective structure for the Servomotors is as follows:
When using the Servo Motor in an environment in which the shaft through-hole is exposed to oil
spray, use a Servomotor with an oil seal. The operating conditions for a Servomotor with an oil seal
are as follows:
exceeding specifications to be placed on the motor shaft. If an excessive radial load is applied, the
motor shaft and bearings may be damaged.
be adjusted.
IP65 (except for through-shaft parts and cable outlets)
Keep the oil level below the lip of the oil seal.
Set up good lubricating conditions so that any oil spray falls on the oil seal.
If the Servomotor is used with the shaft pointing upwards, be careful to not allow oil to accumulate
at the lip of the oil seal.
When the Servomotor is installed in a small space, the Servomotor temperature may rise unless
sufficient surface area is provided to allow heat dissipation from the Servomotor mounting surface.
Take measures such as inserting a radiator plate between the Servomotor mounting surface and
the flange. If radiator plates are not inserted, the motor may be damaged by increased
temperatures. For radiator plate specifications, refer to 3-2 Servomotor Specifications.
Servomotor heating will depend on the material of the mounting surface and on the installation
environment. Be sure to check the Servomotor temperature under actual operating conditions.
The Servomotor temperature may rise sharply if the Servomotor is installed in an environment
such as near a heat source. Take the following countermeasures as required by the installation
environment.
Reduce the load ratio.
Modify the Servomotor's heat dissipation conditions.
Forcibly cool the Servomotor by installing a cooling fan.
