## Abstract

Disclosed herein is a system and method for induction motor intra-core rotor bar surface magnetic field analysis comprising a system and method of excitation and detection by placing a flux sensor array directly between core limbs of a non-contact exciter for observation of the rotor bar current flux pattern.

## Claims

### Claim 1

A system and method for induction motor intra-core rotor bar surface magnetic field analysis, comprising:
a flux sensor array; and
a non-contact excitor having core limbs, wherein said flux sensor array is disposed between said core limbs of said non-contact excitor.
