Checking the armature with the battery without hitting iron, short-circuit faults, putting it on the car to tell the fire, the spark is very strong, but what is the reason for a starting car?

This phenomenon is probably due togeneratorThe high voltage is too high or the load current is too large to cause local unstable damage to the armature or magnetic field winding, but it has not yet developed to the extent of complete short circuit or hit iron, so use low voltage detection, thisgeneratorWhen you hit the car, when you start the insulation, it has not been completely broken, so it is strong with a rowing. Later, there is a rapid development of damage under higher voltages and large currents, so running Can't charge it up. At this time, if the generator is checked, when the wire is the yarn wire, it can be obvious to see the coke phenomenon. In this case, it is generally re-winding. If the coke is not too serious, it can continue to use after the immersion paint is dry. In addition, the generator does not find that the hesitation speed does not meet the requirements, so that the generator is very weak, the voltage is equal to or less than the battery-end voltage, of course, will not be charged.
