Hi All,
Hoping you can advise. I'm building an EV on budget to learn and have fun.
I managed to find an old forklift motor which was a nightmare to source in the UK but 3 months later here I am playing with the brush advance.
Ive attempted the brush advance twice and I've had the same result both times. When I apply power (12v) it turns so slowly (1 rpm?), then stutters stops and the battery begins to hiss and then fire comes out some of the cells...(yes fire, like a firework) then I get scared and disconnect.
I've enclosed some pictures. I can't figure out what I'm doing wrong and any idea's would be nice.
I don't know much about the motor, it came from a Balkancar 72v forklift. It's 11" diameter. I'm not even sure if my series connection is correct but it runs fine when the brushes are in their normal position.
The way the armature is wound it looks like maybe their is a brush advance built in already perhaps??? See my pic with the ruler. (again, just my guess?)
I needed to build a round disc from a 7" tile cutter to hold the brushes for the advance. as seen on one of the pic's.
Many thanks in advance.
