Through this paper, vibration and thermal condition monitoring of the electric drive implementation is analyzed. In the first part of the paper, the physical working principle of a three-phase squirrel cage motor along with NEMA/IEC operating standards are presented first. After that, general mathematical models of forced vibrations and heat, physical parameters that indicate the condition of the squirrel cage motor, and the drive as a whole are given. Frequencies of forcing functions induced by various faults specific to the centrifugal pump electric drive are defined, as well as the methodology and instruments necessary for conducting periodic vibration monitoring as a part of the condition-based maintenance strategy. Along with that, a review of continuous thermal condition monitoring by localized temperature measurement using contact temperature sensors and periodic thermal condition monitoring by global temperature measurement using thermography is given. In the second part of the paper, hands-on implementation of periodic vibration monitoring on five medium and high-power centrifugal pump electric drives of the two water supply network's pump stations is introduced. Also, an example of overheating protection activation enabled by continuous thermal monitoring and its contribution to the evaluation of the electric drive's condition has been presented. Through the analysis of the vibration measurement results derived from periodic vibration monitoring of five centrifugal pump electric drives in various conditions, vibrations characteristic of certain faults introduced in the theoretical part of the paper have been recognized along with the state of the fault's development. Further maintenance actions are considered based on the evaluated condition of the drives, and the final review of conclusions is given.
