Good practice guide to maintain motor efficiency
Engineering360 News Desk | February 22, 2021The Electrical Apparatus Service Association (EASA) has published a “Good Practice Guide” that can help end users obtain three-phase electric motor repairs and rewinds that maintain the motor’s energy efficiency and reliability.
The guide explains in practical terms industry best practice repair/rewind procedures from ANSI/EASA Standard AR100-2020: Recommended Practice for the Repair of Rotating Electrical Apparatus that apply to all three-phase electric motors, including premium efficiency/IE3 motors. Based on rewind studies by independent test facilities, these procedures maintain and sometimes even improve the efficiency of repaired/rewound motors.
The document covers best practices for inspection, testing, mechanical repair and electrical rewinds. It also explains how repair procedures can affect common types of motor losses and motor efficiency, underscoring the importance of requiring service providers to follow the repair best practices in ANSI/EASA AR100-2020.
