Mendocino Motor - very detailed

UPDATE: 07. October 2018 Added: 22mm_solar_cell_holder.stl (for solar cells with a width of 22 mm) This is a mendocino motor designed by me. This motor is levitating and running as hell. I have nearly built 100 of them and they are all still running. The motor achieve a speed of higher than 2.000 rpm. Have a look on my YouTube video of how to assembling (The build instruction is very detailed). https://youtu.be/4mt1YPeHpcE (english) https://youtu.be/aY_bkcrWcqA (german) Just for fun a fully levitating mendocino motor :) https://youtu.be/4JPtCiPu0Ns The following Parts are required: Printed parts: 1 x mirror pad 2 x side part 1 x base magnet bracket 2 x solar cell holder 1 x coil holder Neodym magnets: 4 x side part magnet - N45-12-6 (diameter: Ø 12mm, height: 6mm) 2 x mirror pad magnet - N42-5-5-5 (edge length: 5mm) 1 x base magnet - N42-25-7 (diameter: Ø 25mm, height: 7mm) 2 x shaft magnet - N45-12/4-6 (outer diameter: Ø 12mm, inner diameter: Ø 4mm, height: 6mm) The shaft magnets and the side part magnets should be at least in N45 quality. Others: 1 x enameled copper wire Ø 0,28mm 1 x carbon fibre tube Ø 4mm 1 x chrome steel ball Ø 4mm 1 x aluminium tube Ø 12mm, length 140 mm 1 x mirror or similar round Ø 20mm 4 x seal ring 6 x solar cell (0.5V, 200mA or higher) 1 x super glue I have used solar cells with a dimension of 20 x 65mm, so the solar cell holders are designed for the width of 20mm. If you need other dimensions for the solar cell holder, please leave a comment. You will need M4 headless screws in different lengths for balancing the motor. Only use non magnetic screws like stainless steel A4 and/or polyamide. finally take note if balancing the motor, you need balancing statically and dynamically otherwise your mendocino motor will hit the ground as soon as the sun comes out.
