How to detect the short circuit of an electric motor stator?
You unpack the rotor, the stator of single power supply, for the moment, a long time will burn the coil, you do not know what type of motor has no capacitor, if found stator coil line is relatively new, generally not short. Or look at the capacitor, wiring is a problem.
The stator is seldom damaged, and short circuit multimeter measurement is available. Can not be directly connected with the power supply, do not need to change the stator, it only need to rewind coil. Most of the stator injuries are carefully observed and can be found.
The coils of the series motor rotor are connected on the commutator, and the line resistance between the commutator piece and the piece is very small, about 1 euro. The multimeter measures the same line resistance between the sheet and the piece, and is insulated from the metal body for good, otherwise it is damaged
