4.7 Check before commissioning
Prior to commissioning, important components should be tested. See the table below.

Task
Prior to
commissioning
Electrical
connection
Tighten the plug thread.
(Torque 5 Nm)
Tightness
Check that external bearings are securely threaded onto
the stator with no gap.
(Torque 6 Nm)
Ease of movement
Align the motor for load attachment so that the slider can
move freely.
4.8 Design of water cooling
This paragraph relates to the ATEX linear motor versions with liquid cooling (motor identification numbers
with the suffix
–FC). The heat produced by the motor is dissipated by the liquid cooling. If the motor is
operated with a liquid-cooling, the continuous force value increases many times in comparison with the self-
cooling.
T_Flow:
Flow temperature
T_Back:
Return temperature
ΔT:
T_Back-T_Flow
T_Water:
( T_Back) / 2 (Mean coolant temperature)
Q_Water:
Flow
Δp:
Differential pressure
With the water cooling, the coolant is passed through the cooling circuit of the motor flange.
Starting from the adjusted mean coolant temperature T_Water all other parameters of the cooling circuit may
be dimensioned based on the diagrams referred to:
•
T_Water -> Pv_Max (Continuous power dissipation) -> Q_Water ->
Δp
The design is illustrated by an example in the following.
