Hello together
I am experiencing a sparking problem on a D.C. Motor application with two brushes, permanent Magnets, it is working in gasoline namely a driving a fuel pump. I am not so much experienced about electronics therefore kindly ask for your support. In comparison to normal runnunig motors without any extreme wear at brushes, the following comparisons are done:
Brush holders compared - geometrically ok
Spiral springs compared - ok
Material and grades of commutator and brushes -ok
No assembly failure in pump including motor
No electrical differences in comparison to specs and series armatures
Only the magnetic field is little bit low but within design spec
Kindly request help.
Thanks.
