When a core loss test reveals localized hot spots, or visual inspection identifies physical damage, the ability to repair the damage in a cost-effective manner means the difference between repair or replacement.   

Topics include:   

  • What core loss flux level is correct? 
  • Clearing small localized hot spots 
  • What is the best way to clear surface shorting? 
  • Grinding versus spreading the laminations 
  • “Watt knocking” or physically manipulating the core 
  • Debunking the rusting myth — Coreplate, class F red insulator, waterglass 
  • Restack: complete or partial — Does lamination grade really matter? 

This webinar is intended for owner-managers, shop supervisors, machinists, service center technicians, and safety directors.
