Embodiment Construction

[0052] Hereinafter, the present invention will be explained more fully with reference to the accompanying drawings, so that those skilled in the art can implement exemplary embodiments of the present invention.

[0053] Reference Figure 7 The structure for measuring the iron loss of a stator iron core of a motor according to an exemplary embodiment of the present disclosure may include a C-shaped auxiliary iron core 100 in a substantially letter "C" shape. The C-shaped auxiliary core 100 may have a substantially uniform width in the longitudinal direction. The fixing protrusions 102 may protrude from both end surfaces of the C-shaped auxiliary core 100 in the longitudinal direction and extend longitudinally. The fixing protrusion 102 may protrude from the center of the two end surfaces of the C-shaped auxiliary core 100 in the width direction. The fixing protrusion 102 has a square shape, but it may have other shapes as long as it is inserted and fixed in the groove between the...

Abstract

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.

Description

Technical field [0001] The present invention relates to a structure for measuring the iron loss of a stator core of a motor, and more specifically, to a structure for measuring the manufacturing iron loss of a stator core of a motor, which can accurately measure the stator of the motor by using a C-shaped auxiliary core Iron loss in each step of the core manufacturing and assembly process. Background technique [0002] Generally, an electric motor is called a motor, and is a device that converts electrical energy into mechanical energy by using electric power received by a conductor through which electric current in a magnetic field flows. A motor generally includes a cylindrical stator and a rotor, the cylindrical stator is fixed in a frame and a coil is wound around it, the rotor is disposed inside or outside the stator, and transmits power when rotated by induced magnetic force formed near the coil. [0003] According to the principle of rotation, motors can be classified into ...
