Title:
SYSTEM AND METHOD FOR MONITORING STATUS OF ONE OR MORE COMPONENTS OF ELECTRICAL MACHINE
Document Type and Number:
Japanese Patent JP2023024732
Kind Code:
A
Abstract:
To provide improved systems and methods for monitoring the wear state of a carbon brush of an electrical machine.SOLUTION: A system includes: a carbon brush having an upper face, a lower face on a side opposite to the upper face, and a length from the upper face to the lower face, the length being diminished from an initial length as the lower face of the carbon brush wears away during use; a spring which has a coiled portion and an elongate portion extending from the coiled portion, and is configured to provide a force bringing the lower face of the carbon brush into contact with a rotating conductive surface of an electrical machine; a spacer which is coupled to the upper face of the carbon brush and disposed between the coiled portion of the spring and the upper face of the carbon brush; and a wear state monitor including a sensor. The sensor is configured to measure an amount of diminution in the length of the carbon brush from the initial length thereof as the lower face of the carbon brush wears away during use.SELECTED DRAWING: Figure 1
