Electric Motor Maintenance and Repair Services
Since 2023, CEAR has successfully incorporated Rancan Elettrotecnica, a national reference point for electric motor maintenance, analysis, repair, and balancing services.
For our team, the electric motor repair process begins not when we receive the machine, but when you call us to report an efficiency issue. Our approach is focused on the proactive identification of the root cause of the failure to ensure a lasting solution that prevents recurring machine downtime.
Our Approach to Repair and Reliability
Our attention is paramount, from disassembly to the crucial electrical and mechanical inspections. Our team’s experience translates into a series of specific tests tailored to the machine type, ensuring that no potential cause of failure is missed during the diagnosis. The manner in which the failure occurred provides precise guidance on the measures necessary to guarantee optimal operation.
Often, for specific operational needs (such as humid environments, high temperatures, or inverter-fed motors), we customize the repair process. This involves equipping the electric machine with specialized electrical and mechanical modifications that significantly enhance its reliability.
For comprehensive verification, instrumental predictive analysis [Link to page] performed upon functional restart is essential. This analysis uncovers underlying plant inefficiencies that impact the electric motor, such as unbalance in other rotating components, misalignment, structural resonance issues, or inverter power supply malfunctions.
