Integrated System Build & Test

Team Vision for Integrated System Build & Test Phase

The goal for the Integrated System Build & Test is to assemble all the systems and test functionality. The blades have to interact with the magnetic couples to spin the motor. The blade RPM is found for three blade iterations. More motor research is conducted to ensure the desired output. The housing parts are machined using CNC.

Two iterations of the blades are manufactured by 3D printing. The designs vary in width. The entire system is assembled. The blades are connected to the outer magnetic couple plate, and the second magnetic couple plate is glued to the motor. All of the housing components are assembled and the motor is placed inside the housing.

Test Results Summary

The blade design used successfully spins the generator and allows the system to generate power. The system passes all waterproof testing. The electrical output requires a higher RPM than what was tested at.

Blade Options

Blade variations are designed to understand how the blade interacts with the flow of water.

Blade Variations

There are three main parts to the blade assembly. The hub that holds the blades, the blades, and the top that secures the blades in place.

Housing and Waterproofing

First water proof testing is a success. The gasket is assembled and submerged in water. No water leaked through the connection.

When the system is fully assembled the system remains water proof. In Pool Waterproof Testing (Video).

Electrical Output

The generator is tested by being spun by another motor. The generator is tested with a capacitor and without a capacitor to see the differenct involtage peak-to-peak.
