【国外标准】 IEEE Standard for the Repair and Rewinding of AC Electric Motors in the Petroleum, Chemical, and Process Industries

This document covers general recommendations for the repair of alternating current (ac) 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 shall equate to, the terms wound rotor, generator, and machine. This standard covers reconditioning, repair, and rewind of horizontal and vertical induction motors and of synchronous motors. It applies to all voltages 15 kV and less, and all ratings above 0.75 kW (1 hp). This standard applies only to the repair of motors, 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 shall verify if the repair facility shall be certified by such an agency; Any specific or additional requirements for hermetic motors, hydrogen-cooled generators, submersible motors, or Class 1E nuclear service motors; Direct current (dc) motors.
