ABSTRACT:
A probe includes at least one core and at least one sense coil associated with the core. The ends of the core are arranged in a contact-free, spaced relationship between opposed surfaces of adjacent lamination teeth of a stator. Air gaps are maintained between the ends of the probe core and the opposed surfaces. The total of the two air gaps is constant. The probe is supported on a carriage arrangement and moved along the teeth. Variations in leakage flux produced with the stator energized with an energization winding to produce a flux which is a few percent of is normal energization level, are monitored.
