NOTE
1 This data provides reference values and does not
represent guaranteed values.
2 The values of air cooling depend on the state of
cooling, but lie between those of no cooling and
those of water cooling.
3 The water cooling data is collected based on the
required cooling capability described in Part I,
"SPECIFICATIONS".
4 The values of water cooling for LiS 900A1/4 and
lower models assume that the optional cooling
plate is mounted.
5 This data is calculated from data measured using a
single coil slider unit with peripheral components
such as a heat sink not mounted and with the coil
slider stopped. So, this data is considered to
approximate an increase in temperature under a
relatively severe use condition. An increase in
temperature observed with an actual machine
depends on the state of peripheral component
installation, heat capacity, operation conditions,
and so forth. An increase in temperature slightly
varies, depending on the model of coil slider.
6 By using more powerful cooling, the continuous
rated force can be increased to some extent.
However, be careful not to cause condensation on
the coil slider by excessive cooling.
2.10.2 Temperature Increase on the Surface of the Magnet Plate
A magnet plate itself dissipates almost no heat. So, an increase in
temperature on a magnet plate is mainly caused by radiant heat from
the coil slider and slight heat conduction through the air. This means
that under an ordinary use condition, the temperature on the surface of
a magnet plate increases by about 5 K at most. However, the
temperature can increase more if the magnet plate faces the coil slider
at all times in an area and the operation condition is relatively severe.
In many cases, the magnet plate need not be cooled. To suppress or
shield an increase in temperature by all means, however, take
measures such as blowing air onto the magnet surface or building a
cooling mechanism under the mounting surface of the magnet plate.
NOTE
1 The customer is to prepare a cooling mechanism
for a magnet plate, and equipment and
components required for cooling a magnet plate.
2 When cooling a magnet plate, be careful not to
cause condensation by excessive cooling.
