The high-voltage motor, previously supplied by an Italian
manufacturer, was fully reverse-engineered and produced domestically through a
three-year collaboration between Pardis Petrochemical and an Iranian
knowledge-based firm.
According to Milad Mo'tamedi, head of the electrical unit at Pardis
Petrochemical, the original foreign-made electromotor went offline due to
rotor-stator contact, prompting the company to pursue a domestic alternative.
“Given the high cost of repair and replacement, we opted for in-house
engineering and local development,” he said. “After a thorough technical
evaluation, we selected a domestic knowledge-based company to lead the project,
working closely with our technical teams to design, build, and test the
equipment.”
The new electromotor was installed in Phase I of the complex and ran
continuously for three months, during which it matched the performance of its
imported counterpart in key metrics such as power output, current, vibration
levels, and efficiency—reaching an operational efficiency of approximately 94%.
Mo'tamedi noted that achieving precise dimensional tolerances, rotor
cap alignment, and weld quality were among the main technical challenges the
project successfully overcame.
The electromotor, a critical component of the ammonia unit, powers the
amine pump and is considered one of the most sensitive electrical assets in the
production process. The equipment passed all vibration, electrical, and
functional tests before being brought online.
Strategic Role of Knowledge-Based Firms
Mohsen Moftahi, engineering sales manager at the knowledge-based
company, emphasized the importance of iterative improvement during the project.
“After delivering the initial prototype, we implemented significant
design and material enhancements. The final version was technically sound, reliable,
and fully compliant with operational demands,” he said.
Moftahi also highlighted the project’s economic benefits, noting that
the final cost was about one-fifth that of the foreign equivalent, inclusive of
all design, production, refinement, and testing expenses.
“This wasn’t just an industrial order—it was a turning point in the
domestic development of complex equipment,” he added. “The success of this
collaboration demonstrates how strategic partnerships between the petrochemical
sector and knowledge-based firms can generate national value, create high-tech
jobs, and strengthen the country’s industrial resilience.”
The project aligns with Iran’s broader national goals to support local
production, reduce foreign currency dependency, and expand technology-based
infrastructure in key industries.
