Hello hackers,

So i started this project today and despite everything looking fine, my neodymium magnets are too strong for the motor !
I'm waiting to receive new batch of neodymium magnets from eBay !

The goal is to put everything in a PSX, the motor and the rest must be relatively small.
For that i got a Coprel motor: AC 230V, 50Hz, 17W, 0,17 Amp

For my speed control i'm using a KBMC-23BV, 230 VAC, 50/60 Hz, 2.5 Amp

Main unit:

The motor is attached with 3 cable ties.

For the PSX i've used my dremel to remove a bit of plastic and did my CAD file with solidWorks to put the neodymium magnets, here are some pictures of the design:3D Printed:
But the plastic bend and magnets goes stuck on the motor due to the force.

I plan to add a 40x40mm fan for cooling the motor and find new magnets and revise my CAD design to the according new magnets (or maybe using bakelite instead of plastic, i have no idea).

Power supply pinning of the PSX for future reference:
To be continued.
