3.4 Thermal Management

The driver temperature depends on the ambient and liquid temperature, as well as on the hydraulic operation
point. Figure 11, Figure 12 illustrate the temperature characteristics of the motor depending on these
parameters.

Figure 11: Temperature curves for the IPD-600.2-50 driver @ 25 °C liquid temperature
(Typical data for pumping with pump head LPP-600.29, temperature is measured inside of the
integrated motor and controller, contact temperature of surface is below this temperature.)
