Overview of Status of Analysis, Design, Fabrication, Tests, etc.
We have currently assembled a functioning test rig for a 9 coil array.
We are trying to decide the ideal wiring of these 9 coils to reduce the amount of H-bridges needed in the final design.
We have currently designed the steel plates and magnetic cores used in the device.
We have created drawings to be sent out to local manufacturers.
Accomplishments from Previous Week
Meeting with Sponsor
Purchased 10 H-bridges
Purchased ESP32
Assembled a 9 coil prototype with unique control of the coils to limit the amount of H-bridges needed in the final design
Goals for Next Week (list names after each item). Use specific and measurable objectives.
Pick up the coils from our sponsor (Joshua)
Finalize drawings to be sent out for manufacturing (Seth).
Contact local machine shops to see who can manufacture and assemble our cores and plates.
Send them the coils and our drawings of cores and plates for machining (Anna).
Create a 9 coil prototype with different ways to control the coils (Joshua and Rendale).
Then analyze the magnetic field properties of the new coils.
Sponsor Comments from Last Meeting and Actions Taken to Address these Comments (indicate date of comments and if via email or in person)
In person 1/25
Pursue a 36 coil arrangement.
Design solidworks drawing of the steel plates, and magnetic cores (MAE).
Reach out to local machine shops to manufacture and assemble the 9 coil array to save time.
Set up a test rig with the coils to determine different ways to control the array (ECE).
If the prototype with 6 x 6 coils is able to accomplish alternating between small and large volumes, then we can expand it further to 81 coils
Instructor Comments from Last Meeting and Actions Taken to Address these Comments (indicate date of comments and if via email or in person)
In person 1/23
Concern about the resistance of coils from the manufacturer
Concern about the battery capabilities if we pursue controlling the coils individually.
The battery need to be selected carefully, considering the way how coils are connected based on the new design (in series/parallel)
Comments from Other Students in the Class (indicate date of comments and if via email or in person)
N/A
Risks and Areas of Concern
Finding a battery to produce the requirements needed from the coils.
Not sure if the speed of stir bar's rotation could reach the desired value for stirring the solution.
Resources or Information Required but not Available
None
Schedule
Send out the Solidworks drawings to local manufacturers
Create a 9 coil test rig to determine the ideal coil control
