Good Practice Guide to Maintain Motor Efficiency

  • Category: Promotional/Customer Education Materials
  • Format: Paperback
  • Number of pages: 36
  • Size: 8.5" x 11"

The purpose of this guide is to provide repair/rewind practices and tips that will help service center technicians and motor winders maintain or increase the efficiency, reliability and quality of the motors they repair.

Some of the included procedures derive directly from the 2019 and 2003 rewind studies by EASA and AEMT of the impact of repair/rewinding on motor efficiency. Others are based on the findings of an earlier AEMT study [1998] of small/ medium size three-phase induction motors and well-established industry good practices.

The procedures in this guide cover all three-phase, random-wound induction motors. Much of the guide also applies to form-wound stators of similar sizes.

(Note: This guide provides many specific procedures and recommendations. Alternative practices may accomplish the same results but must be verified.)

Table of Contents Overview
• Terminology
• Energy losses in induction motors

Some elements of this Good Practice Guide To Maintain Motor Efficiency, particularly those concerning changes to windings, do not apply to hazardous area/explosion-proof motors (e.g., UL, CSA, IECEx). Do not use this guide for those types of motors.
