Hello everyone !!This is my first post on this forum but I have been reading
about all the great work you guys have been doing on motor conversions
and was inspired to try one myself.I have no electrical knowledge or experience
but I was helped along the way with a lot of advice from Zubbly. Thanks , Zubbly.
Here is my first successful conversion unit. I'll post some test results soon.
I am now in the process of setting up a pulley system to do some tests.
For this conversion i used four curved skewed anti cogging N40 magnets.
Each magnet measures approximately 1.75" x 1.25" x .25".I have no info on the
motor except that it is a standard 3 phase belted fan motor that used to
drive blowers in a heating/cooling system.This was confirmed by Zubbly.
The shaft measures 5/8".The motor already had 12 lead wires so i did not have
to do any rewiring .There is no cogging with the skewed magnets.I can easily
turn the shaft with two fingers.i had tried this conversions first with
four curved magnets that were not skewed and there was some cogging.With
the skewed magnets there is no cogging .I did try to do some tests using a
cordless drill but i do not know if i am using my meter correctly.Before
rectification i am getting 57VAC at about 354 RPM when i set the meter on
the 200 mark for ACV.After rectifying i did the test again. When i set
the meter on the 1000 mark I am getting 251 VDC at 1160 RPM and 71 VDC
at 345 RPM.When I set the meter to the 200 mark I am getting 70VDC at
1160 RPM and 20 VDC at 345 RPM.What am i doing wrong ?All these tests were done with out load.
