ElectroCore Arabia carried out multiple MV and LV motor rewinding, overhauling, and testing projects at our Dammam workshop. The scope included complete stator rewinding for medium and low voltage motors, armature rewind for DC machines, insulation system upgrades, VPI (Vacuum Pressure Impregnation) treatment, and comprehensive electrical and performance testing to restore motors to OEM specifications.
Scope of Work
- Motor receipt, identification, and pre-inspection documentation
- Complete stripping and removal of old/burnt windings
- Stator core cleaning and slot preparation
- New coil forming and winding insertion (form wound and random wound)
- Inter-turn insulation and phase insulation installation
- Connection and lacing of winding leads
- Vacuum Pressure Impregnation (VPI) with Class F or H resin
- Curing and baking of impregnated windings
- DC armature rewinding and commutator inspection
- Insulation resistance (IR) and polarization index (PI) testing
- Surge comparison testing for inter-turn fault detection
- Hi-Pot testing, run testing, and performance verification
