SKF Dynamic Motor Analyzer EXP4000
Integrated testing capabilities
The SKF Dynamic Motor Analyzer EXP4000 integrates a wide range of monitoring capabilities which meet high quality standards. Designed for in-service monitoring of power circuit issues, overall motor health, load, and performance, it gives the user a comprehensive look at overallmotor integrity. This instrument was designed for remote monitoring from the Motor Control Center (MCC) or through the EP1000 connection. It is a non-hazardous, low voltage, battery operated unit, which makes it highly portable and durable for use in tight and rugged locations. and competitive advantage. This instrument provides data on degradation of motor performance and the effects of overheatingon motor operation. Survey plant wide efficiency, determine load mismatches, oscillating load and transient peak energy. Results are immediate, showing operating efficiencies, thereby allowing the user to determine the true cost of wasted energy.

Comprehensive analysis

Continuous innovation
Continual design breakthroughs demonstrate our ongoing commitment to quality, reliability,

The SKFDynamic Motor Analyzer EXP4000 performs seven major functions to enhance a P/PM program. Within these functions evaluate the incoming power, motor and load utilizing a system wide approach to predictive maintenance, troubleshooting and quality assurance. This motor analyzer offers a wide variety of capabilities for the maintenance professional to understand the condition of the rotating system. Itis programmed to supply information on

voltage level, voltage balance, harmonic and total distortion, rotor cage condition, motor efficiency, effective service factor, overcurrent, operating condition, torque ripple, load history among others. This wide range of tests allows exploration of the true condition of motor integrity and conditions related to motor performance.

Advanced datacollection and organization
Once testing is completed, results can be saved and stored for each motor. This type of documentation is critical for any maintenance program. It allows the recalling of information for true trending capabilities. Test results are managed using standard MS Access relational database file formats. Reports can be quickly generated through the main print console, allowingoperators visual confirmation of motor integrity. The software and data transfer package enables the creation of multiple databases to organize collected data to specifications set by users. This eases communication channels by handling data in a manner that is useful, complete and accessible.

harmonics tests. These issues identify improper tap settings on supply transformers, poorly distributedsingle phase loads, overloading (saturating) supply transformers, excessive VFDs on low voltage busses, excessing non-harmonic frequencies on a VFD, missing line inductors on VFD applications, missing or open power factor correction capacitors along with high resistance connections. Machine performance Conclusively evaluate the operation of the motor, identifying stressful operation and its sourcewith this domain. It looks at Effective Service Factor, Load, Operation Condition, Efficiency, and calculates Payback Period. Commonly found problems include: thermal overloading of the motor, machine deterioration recognition among other items that are directly related to the motors health and the energy wasted with inefficiencies. Current Currrent level and current unbalance are utilized todetermine overall electrical machine health. These parameters are used to determine the following issues overloading, connection issues, miss connections, iron saturation and improperly wound motors. Spectrum This domain has the rotor bar test along with V/I spectrum, Demodulated Spectrum, and Harmonics. It shows current and voltage relationships with regards to frequency. Electrically it will find...
