Big 3D printed BLDC with partial stator

thingiverse

I designed this motor to test an idea of a motor with partial stator.(direct drive wheel) The flux is axial, so a had to add two small bearing to support the rotor. I printed In PLA and it melts after a while, so if someone could please test it with diferent materials. Configuration: 60 poles rotor 6 poles stator Here is a short video of it working: https://youtu.be/qhBkIagETwc List: Print 1 x of each part. 0,3mm Cooper wire 60 - magnets 10 x 5 x 3mm 1 - 626 bearing (6 x 19 x 6mm) 2 - cooler bearings (3 x 8 x 4mm) 1 - M6 x 18mm 2 - M3 x 10mm 2 - m3 nuts 2 - washer 3mm (spacer for the small bearings) 3 - 3mm screws for plastic (fix stator on arm) 6 - iron core( 6mm diameterx 10mm height) 1 - cable tie. Instructions: Assembly the magnet on wheel in pairs ( N S N S...) and the 626 bearing. Insert the iron cores on the Stator Bottom and add the Stator top. It will create a space between the printed parts of 5mm. Assembly the smalls bearing on the arm with the M3 screws and nuts according to the picture. Don`t forget the spacers! The step bellow is just a suggestion. If you test a different winding configuration, please post it here! Cut 3 cooper wires of 1,5m for each phase and wind it 25 turns on each core in pair (U1 V1 W1 U2 V2 W2). Solder it as star configuration. Fix the Stator on Arm with the 3mm screws and use a cable tie to support the cables. Using the M6 screw, assembly the wheel on the arm. I used a Hobby esc 40A to test it. Have fun!
