I hope people are reading (more info) on the right-hand side of the video.

@ Ground loop. Do not use a stepdown transformer , this will introduce extra losses . Unwind generator coil and count the turns .You can then calculate volts per turn . The rewind it with thicker wire to give desired volts out .

Hi All,

Firstly, many many many thanks for the advice. Oscar, Mondrasek, Neptune and Ossie your advice has helped me to achieve a working motor.

Whilst my coil winding skills are improving, I have not managed to get the full 20 metres onto the core. My last attempt (quadfilar per Ossies video) got me to 4 metres wound on before the centre hole closed up. So I have ended up with one core total length 16 metres and the first redo has only 12 meters. Never the less, I am sure you can imaging my suprise when I powered on the 12v and gave the rotor a gentle bump. It continued and continues to rotate at, I think, 170RPM. ( 6 magnets and pulse from hall effect is 35 milliseconds.  1/.035 * 6 ).

I am hoping if time permits, to get my other two coils wound (hopefully get the full 20m on them with more practice). Then see if I can redo the first two.

With the rough setup that I have and switching with a ciruit similar to JLN - cant buy those hall effects, so had to go with 5v regulator and Jaycars 5v H/E sensor, the current draw at 12v is only 300ma and thats with a 12v car lamp in series with the coils (helps to keep the current down and gives me a visual on coil activation).

The shaft  is an ac fan motor from an airconditioners indoor unit - this has been sandwiched between to chip boards for stability.For the rotor, I have used a piece of MDF and the 6 magnets are held in place with copper saddles and a screw.

Once again, thanks for the assist.

Kindest Regards, Penno

Excellent work Penno, excellent work!!!!!!!
