Electrical (AC & DC): 1. Obtain critical nameplate for all motors/equipment, if available, prior to disassembly. Take good pictures of all sides, leads, j-boxes or any accessories prior to disassembly. 2. When feasible, install j-boxes on all repaired motors that are returned to the plant. These jboxes do not need to be in “new” condition, as they are for lead protection only. If not feasible, use best practice for that motor to protect the leads from damage during shipment or storage. 3. Digital reports of all electrical testing must be kept and submitted with every motor. Testing must include mega ohm readings at the required voltage, Polarization Index (P.I.), Phase Balance, Induction, capacitance, (preferred equipment: PdMA MCE Test for off-line testing and PdMA Emax Test for on-line testing.) 4. Never perform a pre-burn on windings prior to job approval. 5. Varnish treatment for new rewinds shall include one(1) Vacuum Pressure Impregnation (VPI) and one(1) overcoat (in VPI varnish) for random and form wound stators with leads attached submerging only connection point of leads to lead insulation. 6. All leads must be a minimum of 12” in length. Do not use glass lead wire for any leads (including jumpers/leads for sync motors). 7. Do not extend leads that are shorter than 12" unless the stator is being rewound or unless the leads are damaged. 8. For rewinds, ensure that only three leads exit the motor frame if capable, except for multiple speed motors or motors with space restrictions. 9. If available, solid barrel lugs are required for all replacement lugs. Lug size #10 and up is to be crimped using an electric or pneumatic powered crimping tool set for the proper torque required for the lug size. 10. Follow Alabama State Port Authority specifications for laminated core testing. Maximum allowable coreloss is 4.0 watts/lb. Quote replacement core iron if this specification is not met. Do not roast & strip windings prior to job approval, even if the hot spots are in the slots. 11. Surge and hi-pot testing reconditioned motors is allowed at the proper test voltages. 12. DC and Synchronous motors: perform AC drop test on all DC field frame coils and record. 13. DC motors requiring a new commutator shall be replaced with a solid riser type commutator. 14. DC and Synchronous armatures/rotors must be submersed, soaked and cleaned in a tank using a desalination process with appropriate cleaning solvent safe for windings. 15. Coat all armature banding with Viton, regardless of if the banding was replaced or not. 16. DC and Synchronous motors: replace all carbon brushes in kind. 17. DC and Synchronous motors: clean, coat with clear insulator and reuse if brush boxes/holders are in acceptable condition. Only replace if they are in unacceptable condition. Materials: 1. All repair parts & components furnished must be new genuine OEM parts only unless approved by ASPA
