SKF Electric Motor Condition Monitoring Powerful visibility into the health and performance of industrial motors and equipment The Power of Knowledge Engineering

Maximize return on investment in the motors that drive your business

Why perform electrical tests on motors? Industrial electric motors are the pervasive engines of commerce. They literally drive industrial output. They support physical plant infrastructure such as the offices and factory buildings throughout a given organization. From oilfield pumping stations to metal refineries, manufacturing production lines and building HVAC systems, motors drive the machinery and equipment that make businesses and organizations productive. These dependencies on motors make it critical for organizations to maintain their motorized equipment effectively and efficiently. They...

Why motors often fail prematurely Degraded insulation and worn or failed bearings are the leading causes of motor failure. There are two main types of insulation in a motor: winding (also known as turn-to-turn) insulation, and ground-wall insulation. Dielectric strength of insulation is the ability to protect one electrified wire from arcing to another wire, or to ground (earth). The dielectric strength of motor insulation naturally degrades over time with normal use. However, when certain common conditions occur, insulation degradation can accelerate. Winding and ground-wall insulation are both...

SKF Electric Motor Condition Monitoring solutions work to: • Reduce electric motor maintenance costs • Maximize motor and machine uptime • Prevent unexpected motor failure and resulting losses • Extend motor life and improve motor efficiency • Improve motor and machine maintenance programs

Static-state motor analysis and monitoring

SKF’s world-renowned Baker motor analyzer products are high-voltage instruments that detect weaknesses and faults in motor insulation and circuitry. These portable predictive maintenance tools perform a comprehensive spectrum of tests to provide a clear, reliable view of a motor’s condition. This helps eliminate unplanned downtime while enhancing maintenance planning and decision-making. SKF Static Motor Analyzer – Baker AWA-IV Series SKF’s flagship Baker AWA-IV static motor analyzers are portable instruments designed to perform automated, repeatable, user-programmable tests that assess motor...

SKF Static Motor Analyzer - Baker DX Series This line of portable static-state motor test equipment is the go-to electrical testing platform for motor rewind, repair and service shops around the globe. PdM professionals appreciate the Baker DX for its lightweight portability for performing motor tests in the field. The Baker DX series boasts more test capabilities than any previous generation of SKF static motor test equipment, and meets the rigorous needs of motor service and repair shops. Baker DX series analyzers are available in configurations that provide just the motor, generator or coil...

Baker ZTX low-impedance test accessory ATF 5000 bar-to-bar armature test accessory This high-current surge test adapter enables bar-to-bar armature tests on very low impedance coils. The Baker ZTX reduces the voltage applied while increasing current to enable accurate tests on DC motor armatures as well as other low-impedance motor components. The ATF 5000 is a handheld fixture designed to work with Baker DX and Baker AWA-IV static motor analyzers in combination with the Baker ZTX (or with the Baker DX-15A, which has integrated ZTX technology). This fixture improves the speed, accuracy and...

Dynamic motor analyzers

Innovative, powerful motor-machine system monitoring Maintenance teams often rely on SKF dynamic motor analyzers to confirm whether a problem with a motor-machine system is electrical or mechanical, and to provide critical information that leads to root-cause diagnostics when problems are identified. SKF Dynamic Motor Analyzer - EXP4000 The portable EXP4000 is the latest in a line of innovative motor test equipment that is designed to gather diagnostic information from motors while they are in a dynamic, or operational state. After safe attachment to a motor through a motor control cabinet (MCC), via...

SKF On-line Motor Analysis System – NetEP Like the EXP4000, the NetEP monitors motors while they are operating (i.e., in a dynamic state). It assesses the quality of power supplied to a motor, the condition of the motor itself, and the load placed on the motor. Unlike the EXP4000, the NetEP is a stationary, network-connected system that continuously measures and monitors the three fundamental elements of a motor-machine system: the power source, the motor itself, and the machinery placing a load on the motor. The system allows maintenance professionals to monitor these conditions remotely, 24/7/365,...

SKF seminars, training courses and conferences SKF offers much more than traditional equipment training programs. SKF helps users of its electrical motor test equipment to optimize their motor predictive maintenance (PdM) repair/rebuild services. With this training, attendees will gain valuable insights to help them cut operating costs while increasing throughput for increased returns on investment. Courses are conducted at our headquarters in Fort Collins, Colorado, or on-site at customer locations. Common course and conference objectives range from basic electric motor theory and technology...

Motor quality control (QC) test systems Motor quality control test systems from SKF are rugged, rack-style units that test motor stators and armatures in high-volume manufacturing environments. These time-tested, semi-customized units combine the most common electrical tests for motor manufacturing. SKF Static Motor Analyzer - Baker WinAST The Baker WinAST automated stator tester was developed for end-of-line quality-control testing in manufacturing of stators, coils, alternators, rotors, and other motor windings. It performs common in-process electrical tests with a semi-custom instrument, assembled...
