Presented by Tom Bishop, P.E.
EASA Senior Technical Support Specialist

The EASA/AEMT Rewind Study was published in 2003, prior to the introduction of premium efficient (IE3) motors. The recently completed follow-up study evaluated motors with premium efficiencies to confirm that, as with the earlier study, the efficiency of these motors can be maintained during rewind and repair by using established good practices.

This webinar covers the results and the technical details of this most recent study.

It will benefit service center managers, customer service representatives, sales representatives, supervisors and technicians.

Intended primarily for service center personnel, the guide which is now an independent document and not part of the complete EASA/AEMT rewind study report, outlines the good practice repair methods used to achieve the results given in both studies. It contains repair tips, relevant motor terminology, and information about sources of losses in induction motors that affect efficiency.
