Claim Text:
1. A structure for measuring iron loss of a motor stator core, comprising: an auxiliary core with two end surfaces in a longitudinal direction, wherein each end surface contacts an inner end surface of two adjacent stator teeth among a plurality of stator teeth in a radial direction in order to measure iron loss of a stator core in which a plurality of slots and the plurality of stator teeth are alternately formed on an inner circumferential surface of a stator yoke in a circumferential direction; a pair of excitation windings provided at portions of the auxiliary core in the longitudinal direction spaced-apart from each other; a B-coil that is a sensor coil provided at the auxiliary core so as to be positioned inside any one excitation winding of the pair of excitation windings; and fixing protrusions protruding from the both end surfaces of the auxiliary core to extend in the longitudinal direction, and inserted into the slot between the two adjacent stator teeth to be fitted and fixed in the circumferential direction.
