Electronic Speed Controller Thermal Management

This experiment was coupled with an acoustic test for NASA’s QUiet Electric ENgine (QUEEN). A cold plate with water was used to cool the electronic speed controller of the motor under different conditions (shown on right). Part 1: Fixed motor RPM, translating to fixed power/heat dissipation (4W per MOSFET) of electrical components, with variable cooling capacity measured by flow rate of cold plate water in gpm. Part 2: Fixed cooling power (1 gpm) with variable RPM.
