3.4 Thermal Management
3.4.1 Motor Temperature
The motor temperature depends on the ambient and liquid temperature, as well as on the hydraulic
operation point and the characteristics (viscosity and density) of the liquid. Figure 16 illustrates the
temperature characteristics for aqueous liquids at room temperature. For higher liquid temperatures and
hydraulic operating points active cooling is recommended for example with the Air Cooling Module ACM-4.2
(see Figure 18) or the Fan Cooling Module FCM-2000.1 (see Figure 19).
Figure 16: Temperature curves for the LPM-2000.x motor @ 25 °C liquid temperature
(Temperature is measured inside of the motor, temperature of housing and sensor electronics is significantly below this temperature)
Figure 17: Temperature curves for the LPM-2000.x motor @ 60 °C liquid temperature
(Temperature is measured inside of the motor, temperature of housing and sensor electronics is significantly below this temperature)
