This report outlines the design and implementation of the electrical circuitry, control design, programming, and physical assembly of a three-phase motor test system made for a customer at Murray State University with a budget of $1,000. It goes in depth into the theory behind motor test stations and the motivation behind different design choices. The three main components of the system are a 3-horsepower motor, a variable frequency drive, and a dynamometer to analyze the output of the motor. An electric circuit was also designed and included to display the different voltages and currents at different points in the system. This was used to physically orient the system and to decide where different parts went. The individual parts were tested in the preliminary design phase and were analyzed for improvements. These improvements were implemented, and the entire prototype was assembled in the final design phase. After this, the station was tested for accuracy and reliability.
