2.3 POWER SUPPLY MODULE (PSM) SELECTION
2.3.1 Selecting a Power Supply Module
Select a power supply module (called a PSM below) required for
driving the linear motor as follows.
NOTE
PSM selection described in this subsection
assumes the use of linear motors only along one
axis. When there is another feed axis or a spindle,
consider and add the PSM capacity required for it.
<1> Check the rated continuous output of the linear motor.
Check the rated continuous output of the linear motor to be used
according to the cooling condition and maximum speed to be
used. Calculate the rated continuous output for each motor model
by using the expressions in the following table based on the
speed range used.
Example:
- Motor model:
Symmetrical arrangement of two L
iS 300A1/4 machines.
- Cooling condition: Water cooling
- Maximum speed to be used: 2 m/s
According to the following table, when water cooling and 2 m/s
is specified, the output for two machines is calculated as follows:
P = (0.1 × 2 + 0.07) × 2 = 0.54 (kW)
