Understanding the market[edit | edit source]

A Market Equivalent Motor by DC Micro Motors People looking to purchase motors similar to the ones produce here would be our target audience.

Things lacking from this design that are to be improved upon:

  • There is a lot of expensive composite materials in this design. This can be cut down to improve cost savings.
  • Being able to build your own at home can cut down on downtime and failures
    • Product is designed for future applications to insert printed magnets.
  • The design is parametric for different pole combinations.

The first prototype of the motor had clearance issues, and we are hoping to have this issue resolved through design iterations and slower print speeds. This has not been tested for comparison metrics, but once we get the magnets and ESC we will begin to track data.

Project goals[edit | edit source]

  1. Create a repeatable and cost effective motor design
  2. Design magnetic slots for future applications
  3. Updating design for coil winding ease
  4. Track data to compare to market motors


Design[edit | edit source]

Hardware[edit | edit source]

  1. Roller Skate Bearings for collar shaft
  2. Magnetic PLA
  3. Shaft for rotational output
  4. RC ESC
  5. Breadboard for electronic wiring
  6. Potentiometer for motor control
  7. Magnets for inserts

Software[edit | edit source]

Arduino Code

Running Motor[edit | edit source]

Just a sample video of our motor running using a basic RC ESC, breadboard, and potentiometer.

The next steps[edit | edit source]

Our teams next steps are to finish gathering materials, running tests and collecting data for comparison. We could fine tune our designs for tighter tolerances to get better efficiency.
