Test Rig Evolution
The picture above was created using Inventor. It was the first design created, it is based on a horizontal alignment.
The image above shows the initial idea for the clamp design. The basis of the idea was to hold the motor and generator, while making contact at the smallest area possible.
Second Preliminary Design
The image above shows a huge change in the initial rig design. This design was changed from a horizontal alignment to a vertical one. The vertical design helps in that gravity is now helping with alignment, as opposed to the initial horizontal alignment, where gravity was pushing the devices down, making it harder to align them.
Final Rig Design
The design above is the final rig design, its the design that has been chosen by the group. This design allows for smooth changes in the distance between the motor and the generator. It incorporates the use of a micrometer, which helps because the gap between the motor and generator can be set to an exact value. This final design also contains two load cells, one which will be calculating the force of attraction between the magnets, and the other will be used to calculate the torque induced by the rotating disks. The load cells are necessary to gather the information required to quantify the performance of the device.
The design above is the updated final rig design, its the design that has been built. This design no longer incorporates the use of a micrometer, a scale is now being used, which still gives accurate and exact values. As demonstrated in the picture above, orange pads can be seeing. These pads consist of a silicon rubber which allows for a higher coefficient of friction, helping the clamps hold on to the motor/generator with ease.
