Efficiency Testing Of An Electronic Speed Controller, Grace Cowell, Matthew Hudson, Marcus Pereira
Mechanical Engineering
This project required the development of a rig that could experimentally determine the efficiency of an Electronic Speed Controller (ESC). The selected design focuses on measuring the losses due to heat from the device and comparing this to its input power. The selected design is a flow rig that utilizes the heat equation q=ṁcpΔT. The rig provides a steady state measurement of the ESC heat output by passing a known mass flow rate of air across the ESC and measuring the temperature difference. It uses a flowmeter to determine ṁ, thermocouples to determine ΔT, and a table lookup to determine …

Mechanical Engineering
PG&E’s Diablo Canyon Power Plant requested a full-sized Flow Loop Simulator to train technicians by giving them hands-on experience. The basic design requirements were established to determine the scope of the project and develop the specific characteristics of the system. The detailed system design is composed of a piping schematic, a three-dimensional layout of the system components and piping, and a skid structure for the support and transportation of the system. Heat transfer and fluid mechanics were used to analyze the system to size components.
