I took motor and circuit board(s) to my friend, he have oscilloscope and other electrical stuff needed and skills to check out, what is the problem with lathe's electricals. |
| John Rudd:
If you any further help let me know....I also have the schematic if needed.... :zap: Good luck with the repair... |
| cre8tor:
I tested motor before I took motor to my friend and run it (slow) about one minute and after running motor it was very hot. So my friend opened motor and noticed something like this, maybe this is the real problem :doh: : I have to take dremel to my hands and try to get motor work. |

What do the brushes look like? Looks like your armature segments are touchi g each other, useba small hacksaw blade to scrape between the segments and make sure they are not shorting to each other |

Brushes were in good shape. But First time when I get this lathe, lathe wouldn't start at all and when I rotated motor from spindle, it like scratches very badly. But when I opened motor, I couldn't see anything what could have damaged commutator. |
