DC Motor Refurbishment

Project Overview

The client contacted Mechanica to tender for the removal, refurbishment and re-installation of a Laurence Scott DC motor. Working on a clean water delivery site, part of the specification was for all engineers to hold a ‘water hygiene card’.

Project Workscope & Completion

Offering the best value solution, and qualified M&E site teams, Mechanica were awarded the project. Mechanica M&E site teams attended site, electrically disconnected and removed the motor utilising the pumping station pendant crane. The DC motor was then electrically tested, stripped, cleaned and all components inspected, with a photographic report being issued to the client. The refurbishment consisted of skimming the commutator, undercutting the micas, supply and installation of new bearings and brushes. The rotor was then dipped in varnish, stoved and dynamically balanced. On completion of the refurbishment process, the motor was installed, electrically connected and commissioned – taking all vibration analysis and temperature readings.
