Abstract
An electric machine includes laminations stacked along a longitudinal axis to define a stator core. The laminations cooperate to define a plurality of slots that extend in a direction parallel to the longitudinal axis, and include a first lamination, a second lamination, and an insulation layer between the first lamination and the second lamination. A plurality of windings is disposed in the plurality of slots, the plurality of windings operable to conduct a current at a desired voltage and a desired frequency. A sensor coil surrounds a portion of the laminations and conducts a first signal. A detector is electrically connected to the sensor coil to measure the first signal and to compare the first signal to a second signal, a difference between the first signal and the second signal being indicative of a short circuit between the first lamination and the second lamination.
