3.3 Thermal Management
The driver temperature depends on the ambient and liquid temperature, as well as on the hydraulic operation
point. Figure 18 and Figure 19 illustrate the temperature characteristics of the motor depending on these
parameters.
Figure 18: Temperature curves for the IPD-100.1-50 driver @ 25°C liquid temperature
(Pumping with pump head DCP-200, temperature is measured inside of the integrated motor and controller,
contact temperature of surface is below this temperature)
Figure 19: Temperature curves for the IPD-100.1-50 driver @ 60°C liquid temperature
(Pumping with pump head DCP-200, temperature is measured inside of the integrated motor and controller,
contact temperature is below this temperature)
