Motorised siren 540 motor
by nic6911, published
I have made a new housing for an old 540 motor I borrowed. The new housing fits a 540 motor and has feet for mounting.
I have made a video with the 540 running the fan. The 540 is old an defect so it takes 20 amps of my powersupply and drops the voltage to around 3-4V! But it makes a lot of noise though!
New impeller unit with screw for fixating the wheel on the axis of the motor.

That sounds a bit strange.. I have tried to slice the model and viewed the layers.. The model seemed okay, but I will try to print it in a few days.
Ok, i printed the parts but i need the wall thickness to be a bit thicker. Also tried to have the Siren_impellerMartinuntitled.stl printed but half way I found out it was printing a big solid cilinder.. and this was not support material.
anyway when i have some time again I will try some more.
Ohh. But the one you refer to is for fixating with bolt and nut. The other one is just pushed on the shaft. I have not tried to print the one you refer to, but only the one that is pushed on the shaft.
I just havent had the time to print and test the one with bolt and nut yet. So would not delete the old file yet...

The wheel is designed to fit a 3mm shaft.
Mount the motor in the housing and push the wheel on the motor, fixate with screw and m3 nut.
