Services
Electric Motor Repairs
Our electric motor repair service addresses AC, DC, and servo motors up to 500kW. We conduct core loss testing, coil winding, and impregnation to restore functionality. With 24/7 emergency support, we minimise downtime through rapid diagnostics and precision overhauls. Our engineers utilise laser alignment to ensure optimal performance post-repair.
Laser Alignment
Precision laser alignment reduces machinery vibration by 50%. We correct angular and parallel misalignment in motor couplings, extending bearing lifespan. Our technology provides documented measurements for compliance and maintenance planning, improving energy efficiency by up to 15% through reduced friction.
Vibration Analysis
Using Emerson 2140 data collectors, we identify bearing faults and mechanical looseness through vibration signatures. Our Dragon Vision motion tracking visualises pipework failures and resonance issues. This predictive maintenance approach reduces unscheduled downtime by detecting problems before escalation.
Thermography
Our infrared surveys detect overheating components and electrical faults in distribution systems. Non-intrusive inspections identify insulation defects and overloaded circuits while equipment remains operational. This proactive method prevents failures, saving up to 30% in maintenance costs through early intervention.
AEGIS Ring Installation
We install AEGIS SGR and PRO Series rings to protect VFD-driven motors from electrical bearing damage. This solution channels harmful shaft currents safely to ground, preventing premature failures. Recommended during motor start-up, it extends bearing lifespan beyond three years in high-risk applications.
