The main cause of the burning of refrigeration compressor windings

The damage of the motor coil is mainly manifested as the destruction (short circuit) and open circuit of the stator winding insulation. After the stator winding is damaged, it is difficult to be found in time, which may eventually cause the winding to bur器2䀀
