Electrical Capabilities

Heavy Electric Motor Rewinding & Testing

Featuring computer-controlled burn-off ovens, precision automated coil winders, VPI epoxy resin vessels, and dynamic load testing bays in Jeddah, Dammam, and Yanbu.

Class H (180°C) Inverter-Duty Copper Rewinding

High-grade corona-resistant copper magnet wire and Nomex slot liners engineered to withstand severe VFD voltage spikes (dV/dt) and extreme Gulf ambient operating temperatures.

Vacuum Pressure Impregnation (VPI) Epoxy Treatment

100% void-free solventless epoxy resin penetration ensuring superior dielectric insulation strength, moisture resistance, chemical protection, and mechanical coil rigidity.

Baker Surge, Hi-Pot & Core Loss Diagnostic Testing

Comprehensive computerized testing suite including insulation resistance (Megger), polarization index (PI), surge comparison, and core loss stator evaluation before and after rewind.

Mechanical Journal Restoration & VFD Integration

Rotor dynamic balancing to ISO standards, bearing journal thermal spray metallizing, housing line-boring, and variable frequency drive (VFD) control panel integration.

Suffering from Motor Burnout or Insulation Trip?

Our rapid technical teams provide 24/7 teardown, rewind, and emergency site motor replacement.
