Recommended practice for the repair of rotating electrical apparatus, 2020 ed.

November 11, 2020 – An updated edition of the American National Standard for the repair of motors and generators, ANSI/EASA AR100-2020 “Recommended Practice for the Repair of Rotating Electrical Apparatus”, was recently published.

“If a service centre conducts repairs in accordance with ANSI/EASA AR100-2020, end users can rest assured they receive a quality repair that maintains reliability and efficiency,” said Linda Raynes, EASA president & CEO.

The 2020 edition describes industry best practices for the repair, rewinding, and testing of electrical apparatus to maintain or enhance the reliability and energy efficiency of both AC and DC motors and generators.

EASA says the 2020 edition contains more than 40 revisions. Changes include revised performance levels for the surge testing of motor windings, as well as new requirements relating to terminal leads, cooling systems, and thermal protectors.
