Factors influencing the decision
When deciding between overhauling and replacing an electric motor, the following must be analyzed:
- The motor’s age and construction
- Energy efficiency class
- The cost of overhaul compared to the price of a new motor
- Availability of spare parts
When overhaul pays off
Overhaul is justified when:
- The motor’s mechanical structure is undamaged
- The windings can be properly restored
- The motor has a specific/custom design
When replacement is the better solution
Replacement is recommended if:
- The motor uses outdated technology
- Energy efficiency is low
- The repair cost exceeds economic justification
Conclusion
Expert technical assessment is the key to making the right decision — one that ensures long-term stability and efficiency of the industrial system.
