Apparatus and method for measuring performance of motor ring iron core

Abstract

A device and method for measuring the performance of a motor ring iron core. The large-section cylindrical conductive core of the device runs through the annular iron core to be tested, and a voltage drop occurs at its two ends when it is energized; the upper and lower conductive joints are respectively connected to one end of the conductive core, and one of them is detachable; The measuring circuit is connected with the upper and lower conductive joints; the two ends of the wires passing through the tested ring iron core output the low voltage induced from the tested ring iron core; Or built-in program operation for display, including active power values ​​obtained based on the high current, low voltage or voltage drop values, or iron core performance values ​​obtained based on the above values. The measurement procedure is to adjust the power supply to select high current to measure low voltage or select low voltage to measure active power after determining the magnetic circuit parameters of the sample yoke. The measuring device and method can measure the performance of the iron core with relatively low-cost software and hardware circuits, and the operation is relatively convenient.

Description

technical field [0001] The invention relates to a device and method for measuring the performance of an annular iron core of a motor, and the IPC classification belongs to G01R33 / 12. Background technique [0002] The quality control of the motor core performance is traditionally measured by measuring the performance of the raw steel sheet used to manufacture the motor core or by judging the no-load performance of the product motor. Both operations are cumbersome or the measurement results are not direct. [0003] Except as specified in this manual, refer to "Basic Circuits" (National Defense Industry Press, 1st edition in 1979) and "Handbook of Electrical Engineering" for relevant terms and common sense. Contents of the invention [0004] The technical problem to be solved by the present invention is to provide a performance measuring device and method for a motor ring iron core, which is simpler than the traditional measuring device and method, and has direct measurement ...
