New IEEE Standard - Active.
Best practice methods for the inspection, testing, mechanical repair, rewinding, assembly and acceptance testing, as well as recommended and maintenance practices for direct current electric motors and generators, are covered in this recommended practice.

This document covers general recommendations for the repair of dc electric motors and includes guidelines for both the user and the repair facility. It is not intended to replace specific instructions contained in the manufacturer’s instruction book or in any contractual agreement between a manufacturer and a purchaser of a given machine. For the purpose of this document, the term “motor” is used in lieu of, and it is equal to, the terms dc motor, dc generator, and dc machine. This standard covers reconditioning, repair, and rewind of horizontal and vertical wound-field direct current motors and generators. It applies to all ratings above 0.75 kW (1 hp). This standard applies only to the repair of machines, and in cases involving modifications to the basic design, care must be taken so as not to negatively affect the safety and reliability of the motor. Excluded from the scope of this standard are the following: Specific requirements, certification, and inspection required for explosion proof, dust ignition proof, flameproof, and like motors having a listing issued by a Nationally Recognized Testing Laboratory (NRTL), for example, American Bureau of Shipping (ABS), Underwriters Laboratories, Inc. (UL), Factory Mutual (FM), and Canadian Standards Association (CSA). For motors in this category, the user should verify if the repair facility should be certified by such an agency. Also excluded are permanent magnet (PM) machines.
This standard is intended to be used and referenced by users of motors that need repair as well as by users and operators of establishments that offer motor repair services. It has been developed primarily for the needs of the petroleum, chemical, paper and other process industries but can be adapted to other applications or industries such as traction motors, rolling mill motors, mine hoists, motor-generator sets, excavators, ship propulsion and oil field. The use of this standard by users and repair facilities is expected to result in higher quality, cost-effective, timely repairs. It also provides a means of evaluating repairs and facilities.
