Reverse Engineering Project — 1,450 kW High Voltage Motor

We just completed a reverse engineering project involving a high-voltage electric motor, rated at 1,450 kW, 12 poles, 6.6 kV / 50 Hz, frame size 800.

The unit was built to support heavy industrial operations within the mining sector.

Technical Overview

• Power: 1,450 kW
• Voltage: 6.6 kV – 50 Hz
• Poles: 12
• Frame Size: 800
• High Voltage configuration
• PT100 temperature sensors in both stator windings and bearings
• Space heaters for anti-condensation protection
• Integrated flywheel and coupling assembly

Engineering Scope

This project required full reverse engineering of an existing machine, ensuring dimensional compatibility with the original installation while upgrading monitoring and protection features.

Special attention was given to:

• Thermal monitoring (windings and bearings)
• Mechanical balancing with flywheel integration
• High-voltage insulation integrity
• Structural robustness suitable for mining environments

Frame 800 machines operate at the upper end of industrial motor construction. Handling, assembly, and testing require dedicated infrastructure and precision alignment procedures.

This project remains part of our ongoing commitment to delivering large-scale, high-voltage solutions where reliability is not optional.
