摘要
This paper refers to a "DC Motor Duty Meter" project which aims to develop a comprehensive condition monitoring tool for DC motors used in mining excavators. The paper presents experimental waveforms measured internally and externally to the motor at different rotation velocities. The paper focuses on analysis of these waveforms both in time and frequency domains. The findings of the analysis are discussed in relation to the motor performance and commutation quality.
