- Burned PM generator charging a lithium battery. How do I make them play well together?
I have a burned stator for a PM generator mounted in the accessory case of an internal combustion engine. The stator has 2 sets of 5 coils creating 2 20 amp generators. I am using a lithium battery and the engine builder blames the battery for the burned stator. He says the lithium battery has much lower internal resistance that a lead acid battery and thus will allow the generator to create a level of power that overheats the stator. I would like information on two approaches to the problem.
First: is there a way to mimic the resistance of the lead acid battery and still allow the lithium battery to charge. The goal would be to throttle the current output of the generator.
Second: I'm thinking of trying to rewind the stator myself. I would appreciate any suggestions as to how to reduce the heat damage potential. I believe the builder used hi temp magnet wire, probably 200C. I would use 240C. It doesn't look like any type of overall coating was used.
I will appreciate any help, suggestions.
