We offer preventive and predictive maintenance plans for electric motors and generators


Preventive Maintenance

AC Motors

The induction electric motors  have multiple applications in the industrial sector. Our company knows what is necessary for their proper operation, so we have specialized procedures for the maintenance of your AC motors.

Among the services we offer:

  • Stator Core Loss test
  • Stator initial insulation tests
  • Disassembling and diagnosis of parts
  • Measuring of mechanical tolerances of shafts and End Bells in modern lathes
  • Bearing inspection and mounting using SKF procedures

DC Motors

The DC motors, due to their characteristics and design, require maintenance more frequently, since they are constituted by two independent windings and additional elements that make them more complex.

Among the services we offer:

  • Armature Core loss tests.
  • Initial insulation tests to field and armature windings.
  • Dissassembly and diagnosis of windings and parts.
  • Cleaning, drying and varnishing of field and armature windings.
  • Measuring of mechanical tolerances of shafts and End Bells.
  • Inspection, disassembly and assembly of bearings with SKF procedures.
  • Bearing replacement using induction methods.
  • Commutator surface improvement.
  • Concentricity verification
  • Brush holders cleaning, installation and brush seating. 


Predictive Maintenance 

Our company has digital insulation testers, specialized tools for predictive maintenance, which can be used in the workshop or in the field to monitor the integrity of the motor and its insulation. Our equipment can be used in Alternating Current (AC) and Direct Current (DC) Motors, Synchronous Motors, Wound Rotors, Armatures, Field Coils, among others. With our testers we can execute the following tests and more:

  • Surge Test
  • DC Hipot tests
  • Thermography
  • Partial Discharges
  • Vibration test
  • Shaft leakage current test
