Component list: (1) motor mount - sheet metal, (2) DC motor, (3) rotor body, (4) rotor mount - sheet metal, (5) magnets, (6) screw
Task 1, Rotor Mount Fabrication
Cut rotor mount metal strip from bulk strip metal. (photo 2)
Rotor mount length is set by the by desired magnet location. It is spaced approximately 80% of the stir bar length. Using longer bar magnets on the rotor body allows for a wider range of magnetic stir bar sizes.
The motor shaft through hole (red) should be larger then the shaft (R).
The screw holes (r) to attach to the Rotor Body are spaced symmetrically (L) around the center. Be careful not to place them too far, where the magnets will be attached.
