Reverse Engineering
Precision Replication for Seamless Replacement

When legacy motors reach the end of their life cycle and direct replacements are no longer available, reverse engineering offers a reliable and efficient path forward. It’s not just about copying—it’s about recreating with precision.

Our latest project involved a medium-voltage, small-frame size 315 motor, designed with a custom base plate to achieve a 425 mm shaft height, exactly matching the client’s original setup. The motor was also fitted with an invertible terminal box, allowing flexible mounting on either side (left or right)—a small but critical feature for operational efficiency and warehouse optimization.

This is just one example of what we do:
We carefully analyze and deconstruct original motors, understand every structural and functional aspect, and then recreate them using advanced technology and a commitment to exactness. From torque and load characteristics to dimensional fit and mounting configuration, our reverse-engineered motors are designed to integrate seamlessly into existing systems.

Whether it’s restoring equipment for industrial use or replacing discontinued models, we deliver motors that match the original in function, form, and performance—while often improving reliability in the process.

When replacement isn’t available, we recreate it. Accurately. Reliably. And on time.

MV Project Delivery to Power Plant

Valiadis S.A. is proud to announce the successful completion of a medium-voltage motor replacement project for a major power plant, following our participation in an international tendering process.

Our company was awarded the contract for the design and manufacturing of four custom medium-voltage electric motors, and the project has now been completed, having passed a full load witness test with excellent results.

All motors were individually engineered to meet exact performance and dimensional requirements, replacing legacy units through a reverse engineering process. This marks the second time we have delivered motors to the same facility—the first was back in 2017. Such repeat trust from our customers is a source of pride and a strong endorsement of our quality and reliability.

Project Specifications:

• 2 pcs – 3-phase motor, 1200 kW, 1500 RPM, B3, 6 kV / 50 Hz, IP55, water-cooled – Model: TMKHV-W 500-4

• 2 pcs – 3-phase motor, 1200 kW, 1500 RPM, B3, 6 kV / 50 Hz, IP55, water-cooled – Model: TMKHV-W 450-4

This project highlights our ongoing commitment to engineering excellence, customer satisfaction, and long-term support for demanding industrial applications.

Complexul Energetic
Medium Voltage Motor Project – Romania

In July 2017, we proudly completed the delivery of four medium-voltage electric motors to Complexul Energetic Oltenia (CEO), one of Romania’s most significant contributors to national energy production.

The project was awarded to Valiadis S.A. through an international tendering process finalized in late 2016. Following extensive coordination, testing, and quality control, all items were successfully manufactured, approved, and delivered on time.

Complexul Energetic Oltenia is a strategic power provider in Romania, with over 13,300 employees and a vital role in maintaining the country’s energy security. With substantial coal reserves capable of sustaining electricity generation for decades to come, CEO plays a critical part in the Romanian National Power System.

The motors we delivered were custom-built to meet precise technical requirements and replace CEO’s aging equipment—enhancing reliability and efficiency across their operations.

Project specifications:

• 3-phase motor, 1000 kW, 1000 RPM, B3, 6000 V / 50 Hz, IP55, IC611 – Model: TMKHV 500-6

• 3-phase motor, 640 kW, 3000 RPM, B3, 6000 V / 50 Hz, IP55, IC611 – Model: TMKHV 400-2

• 3-phase motor, 500 kW, 1500 RPM, B3, 6000 V / 50 Hz, IP55, IC411 – Model: KHV 355-4

• 3-phase motor, 400 kW, 1500 RPM, B3, 6000 V / 50 Hz, IP55, IC511 – Model: KHV 560-4

This delivery reaffirms our ability to execute complex international projects with precision, responsiveness, and long-term reliability in mind.

High-Power Medium Voltage Motors Delivered as Drop-in Replacements

In November, we delivered two high-performance medium-voltage electric motors to a cement plant, following a request for fully interchangeable spare units. To meet the requirements, both motors were developed through complete reverse engineering, ensuring that every detail—mechanical and electrical—matched the client’s original specifications.

Delivered units:

• 2400 kW, 6 poles, 4.16 kV, 50 Hz, IC616, Frame size 560

  • Inverter duty motor

• 900 kW, 6 poles, 4.16 kV, 50 Hz, IC611, Frame size 500

  • Slip ring motor

Both motors are now on-site as operational-ready spares, providing immediate backup capability for critical cement plant operations.

This project reflects our ability to deliver custom, high-power motor solutions designed to integrate seamlessly into existing infrastructure—especially in industries where downtime is not an option.

Power Plant
Medium Voltage Reverse Engineered Motors Delivered and Running

In June, we successfully completed the delivery of two medium-voltage electric motors to a power plant, following an international tender in which Valiadis S.A. was selected as the best bidder.

The motors—designed to replace existing equipment—were supplied as spare units and required full reverse engineering to match the mechanical and performance specifications of the originals. After delivery, both motors were installed and are now operating with excellent results.

Delivered units:

• 630 kW, 8 poles, Frame size 560, 6.3 kV

• 280 kW, 8 poles, Frame size 450, 6.3 kV

This project is yet another example of our expertise in supplying customized medium-voltage solutions—especially when exact replication is required to ensure seamless integration with legacy infrastructure.
