Professional motor rewinding for DC and AC, LV and HV motors up to 11 kV. ISO 9001:2015 certified.
At GEF Technologies Sdn Bhd, we specialize in professional motor rewinding services for DC and AC, LV and HV motors up to 11 kV. With over 20 years of engineering expertise and ISO 9001:2015 certification, we deliver reliable, efficient, and long-lasting motor repair solutions trusted by industries across Malaysia.
Our rewinding procedures are performed in accordance with EASA AR100-2020 and IEC 60034 standards. Such a process typically involves the following steps:
Testing insulation resistance, winding condition, and root-cause analysis to fully understand the extent of damage before proceeding.
Removal of damaged windings and preparation of stator core for insertion of new coils. Dry-ice blasting and washing bay used for thorough cleaning.
Making of precision-formed coils with insulation for protection. Each coil is manufactured to exact winding data specifications.
Winding insertion, connection, and resin impregnation. For HV motors, resin-rich coils are used for superior insulation performance.
High temperature curing of resin in temperature-controlled ovens for long-term durability. Lathe machining ensures correct fitment of all rotating components.
Perform various electrical tests (surge, hi-pot, insulation resistance) and mechanical tests (vibration, bearing noise) to ensure quality before dispatch.
Paint job and preparation for reinstallation at customer site. Our team can assist with on-site commissioning and laser alignment.
