摘要： A structure for measuring iron loss of a motor stator core is provided. The structure includes an auxiliary core whose both end surfaces in a longitudinal direction come in contact with inner end surfaces 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 is provided at portions of the auxiliary core in the longitudinal direction spaced-apart from each other. A B-coil that is a sensor coil is provided at the auxiliary core so as to be positioned inside any one excitation winding of the pair of excitation windings. Fixing protrusions protrude 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. Accordingly, it is possible to quantitatively and accurately measure iron loss of the motor stator core for each manufacturing process.

摘要： A stator support member of a rotating electrical machine is provided with a cooling channel formed in the stator support member to cool a stator. The stator support member is manufactured to have the cooling channel of a hermetically sealed structure so that a cooling fluid may flow along the cooling channel. In particular, the support member having the cooling channel is divided into a ring-shaped outer part and a ring-shaped inner part (two-piece type) and the separately manufactured ring-shaped outer part and inner part are combined together.
