Brushless motor multi-pole magnet ring magnetic flux online detection device and detection method

Abstract

The invention belongs to the field of detection devices, and provides a brushless motor multi-pole magnet ring magnetic flux online detection device which aims to solve the problem that an existing magnetic flux detection device fails to automatically carry out judgment and data record tracing. The brushless motor multi-pole magnet ring magnetic flux online detection device comprises a detection unit, and a Hall sensor used for converting magnetic flux signals into voltage signals is installed on the detection unit. The detection device further comprises an A / D card used for collecting the voltages signals of the Hall sensor; a processor used for processing the signals collected by the A / D card; a storage device used for storing collected signal data; and a printer used for generating labels. The A / D card transmitted the collected signals to the processor; a qualified value range is stored in the processor; when the signals collected by the A / D card are within the qualified value range in the processor, the processor controls the printer to print the labels; and when the signals collected by the A / D card are out of the qualified value range in the processor, the processor emits out alarming signals. The brushless motor multi-pole magnet ring magnetic flux online detection device is capable of automatically recording a measurement result, and a unique code is generated for a product, so that tracing management is convenient.

Description
