Vibration analysis provides detailed information about a machine’s condition. It has become part of the toolbox that most maintenance teams use to detect and diagnose problems and prioritize maintenance schedules. Our teams of vibration experts composed of engineers and technicians, all certified by the Canadian Machinery Vibration Association (CMVA) are assisting local maintenance teams with various vibration-related mandates, whether punctual or on a regular basis.

The strength of our vibration team resides in the detailed reports they provide, explaining their findings and listing possible causes and likely solutions to fix the issue before a dramatic failure occurs. Motion Electric can also perform the corrective measures, if needed. That is why we are your rotating equipment specialist!

Problems detected through vibration analysis:

  • Bearing wear
  • Unbalance
  • Misalignment
  • Bent shaft
  • Eccentricity
  • Resonance
  • Coupling looseness
  • Motor rub
  • Babbitt bearing instability
  • Gear faults
  • Belt problems
  • Etc.

Vibration analysis can be performed on mechanical and electromechanical units of the power train:

  • Electric motors and generators
  • Ventilators
  • Gearboxes
  • Pumps
  • Extruders
  • Blowers
  • Grinders
  • Etc.

Different types of vibration analysis to assess any type of equipment:

  • Flux and current analysis
  • Gearbox-specific vibration analysis
    • Low-speed diagnostic as low as 35 RPM
    • Spectral analysis
    • Lon wave form analysis technique
    • Gear profile analysis
    • Dedicated filters
  • Torsional vibration analysis (for shaft fissures)
  • Natural frequency investigation
  • Impact test
  • Dynamic absorber solutions
  • Babbitt bearing verification
  • Proximetric sensor readings
  • Orbit analysis
  • 16-channel parallel readings

Fiberscope inspection

Fiberscope inspection (or videoscopic inspection) uses a small camera mounted on a flexible fixture to take measurements in extremely small spaces like, for example, inside a slurry pump. One of the key features of this kind of inspection is that it can be performed without tapering the manufacturer’s seal thus not voiding the warranty.

Fiberscope inspection also reaches hard-to-access places without completely dismantling the unit, cutting the preventive maintenance time significantly.

Fiberscope inspection can be useful in the following situations:

  • Troubleshooting
  • Assistance in damage assessment
  • Staff training
  • Compliance inspection prior to start up
  • Gearbox gear inspection
  • End-of-warranty inspection
  • Bearing damage inspection
  • Measuring faults and monitoring their progression (starting at 0.002″)

Predictive electrical audit

Predictive electrical analysis is used to determine the current condition of an electric motor or generator’s insulation system.  When performed on a regular basis, inflection in the result helps detect deterioration before it causes a catastrophic failure.

Predictive electrical audits are recommended for all critical units and can include an assortment of the following:

  • Core loss test
  • Stator hot spots test
  • ELCID test
  • Partial discharge
  • Slow roll test
  • Single-phased rotor test
  • Roundness check
  • Turn-to-turn insulation test
  • AC drop volt test
  • Winding resistance
  • Insulation resistance
  • Megger
  • Polarization Index (PI)
  • Dielectric Discharge Test (DDT)
  • Laser alignment
  • Vibration analysis
  • Commutator profiler
  • Bar-to-bar resistance
  • Bar-to-bar drop test
  • Field stator volt drop test
  • Neutral setting verification
  • DC neutral point setting
  • Strand-to-Strand Testing
  • Surge Testing (for multi-turn diamond coils)
  • AC testing between turns (for multi-turn stator bars)
  • AC High Voltage Testing
  • Tan Delta Tip Up Testing
  • Semi-Conductive Coating Contact Resistance
  • Voltage Endurance Testing
  • Partial Discharge Testing
  • Blackout/ Ultraviolet Imagining

Predictive mechanical audit

Predictive mechanical audits are used to determine the current condition of an electromechanical unit.  When performed on a regular basis, inflection in the result helps detect deterioration before it causes a catastrophic failure.  Combined with Vibration analysis and fiberscope inspection, the mechanical audit gives the maintenance teams a complete 360 view of the unit’s condition.

Motion Electric Motor Services’ mechanical audit can include:

  • Laser alignment
  • Dynamic balancing
  • Dimensional integrity check using CMM equipment
    • FARO arm
    • Laser tracker
  • Oil analysis
  • Lubrication routines
  • Bearing analysis

Custom preventive maintenance programs

Motion Electric Motor Services’ experts team up with local maintenance crews to plan and perform preventive maintenance.  An optimized maintenance plan will ensure that the condition assessment of all critical units is updated frequently with pertinent data to make slight changes in the data easy to spot.  A high-performance maintenance plan is tailored to the specificity of each plan, taking into account the type of production, ease of access to spare parts or spare units, and critical operations.  An effective maintenance plan delivers optimal reliability and productive shutdowns.
