Motor Current Analysis is an effective tool for diagnosing problems within the rotor circuit of induction and wound rotor motors such as:

Motor Current Analysis Benefits

• Performed on motors working under normal operating conditions, which allows for easy scheduling and extremely accurate test results.

• Motors can be scheduled for repair, reducing downtime and the cost of catastrophic failures.

• Results are stored in our computerized Predictive Maintenance Database for trending or future use.

• Current analysis can be used in conjunction with vibration analysis to help identify electrical vibration problems.

Roll Profile Analysis: Measuring Relative Motion Between Press Rolls

• Detects eccentric rolls

• Roll cover and felt fabric defects

• Roll imbalance

• Roll and felt barring (corrugation), together and separate

• Improper operating ratios of rolls and felt

Exact Measurements

Roll Profile Analysis uses a synchronization sensor to plot the roundness of each roll.

Operating Deflection Shape Analysis

L&S Electric's Operating Deflection Shape (ODS) Analysis allows you to actually see the dynamic behavior of your operating machinery through 3-D animation.

With this vital information, you have the ability to take appropriate action to correct resonance or looseness related problems and prevent machine and component failure.

Animating Equipment in Operation

ODS is the easiest way to actually see how a machine or structure moves during operation.

Foundation Security

Not only does ODS let you see how your equipment moves, it also detects problems in bases and motor frames.

Relieve Stress Before It’s Too Late...

...With 3-D ODS Imaging!

Electrical Winding Analysis Program

Winding Analysis Benefits:

• Increases equipment life

• Reduces repair costs

• Improves machine efficiency

• Reduces unscheduled down time

Winding analysis detects early stage problems in electrical equipment, which allows equipment to be repaired during planned down times. This reduces costly unscheduled shutdowns and can minimize repair costs associated with catastrophic failures. This nondestructive test can be used for motors, generators, transformers, and many other types of windings.
