Rewinding the generator is necessary in order to restore its normal operation. The winding can burn out due to contamination and loss of standing insulation. This procedure can be performed at home as well.
Instructions
Step 1
Take out the generator stator, the winding is on it. Place the stator on a non-combustible surface such as bricks or metal. Set fire to the old insulation, do not be afraid, it will not deteriorate the magnetic properties, and will not spoil the iron. Pre-measure the length of the protruding parts, because for some generators this is critical - it will not fit into the case.
Step 2
Count the number of turns, sketch the winding scheme and mark on the stator where the winding leads begin and end. Thoroughly clean the stator from dirt with a steel brush and prepare it for winding. Get syntoflex, which is an excellent insulating material, it is very durable and does not cut at the folds.
Step 3
Make insulating spacers that protrude 3-4 mm on each side of the groove. Wind half the turns of one phase and continue winding in the other direction to overlap the empty front ends. After completing one phase in this way, mark its end. Also wind the other two phases, making sure that the beginnings and ends of the windings are of sufficient length.
Step 4
Carefully seal the grooves, put those parts of the gaskets in them that protrude outward. Check that nothing protrudes beyond the iron inside. Try on the stator in the generator covers. Look carefully to see if there is any contact between the winding and the case. If such a defect occurs, then take measures to eliminate it.
Step 5
Connect and solder the winding leads. Insulate them thoroughly and check for a short circuit between the phases, if any, then make additional insulation at the point of contact. Immerse the stator in a special insulating impregnation varnish. After that, dry it by placing a light bulb inside, or in the oven over low heat. Install the stator in the generator.
