Summary:PURPOSE:To automatically detect the defect sections of windings, by permitting electrode brushes to follow the windings and by detecting discharge with a discharge detector. CONSTITUTION:Electrode brushes 3 start rotating with the driving of motors 4 set at four sections of the connection side of windings 2, the counter- connection side, the inner diameter, and the outer diameter in the left and right directions. If there is any damaged section on the windings 2 while the electrode brushes 3 are turned one time along the windings 2, discharge or leakage current is generated at the damaged section between the windings 2 and the electrode brushes 3, and the discharge or the current is detected by a discharge detector 6, and signal is fed to a controlling micro-computer 7. By the controlling micro-computer 7, the electrode of the generated signal of the damaged section and the output of a rotary encoder 5 for detecting the section are read, and the damaged section of the windings 2 is stored.
