4.1.3 Determination of water pressure p
To achieve the water flow rate determined in 4.1.2, the hydraulic resistance of the cooling circuit in the motor
must be overcome. The maximum pressure difference across the motor's water connections can be
determined from the following diagram, which depends not only on the flow rate but also on the type of
motor.
Example
•
Q_Water: 1.6 l / min
→ ∆p:
2 bar
Corrosion protection
It is advised to add a corrosion protection into the cooling medium (water). A suitable agent can be, for
example, Protectogen C Aqua by Clariant. Information of the mixing ratio between the cooling medium and
the corrosion protection agent can be taken from the manufacturer's instructions.
•
Mixing of various corrosion protection agents is to be avoided.
•
Corrosion protection products must be matched to the materials of the cooling circuit
(see table of materials in the cooling circuit).
Mounting
The supply or conduction of the cooling medium to the stator is carried out via two connecting thread (see
illustration above). The connection can be realized by M5 push-in fittings.
