Motors are the driving force of industrial production. New approaches to motor monitoring, alignment, testing, and connections are saving time and costs while improving safety. At the same time, energy-saving motors and intelligent drives are boosting efficiency and performance while facilitating troubleshooting.
Maintenance made easy
Installing condition monitoring sensors directly on motors can be expensive or even impossible in some cases. The SAM4 predictive maintenance solution from Semiotic Labs was designed to analyze current and voltage data from inside the motor control cabinet, and it uses machine learning to recognize patterns and detect developing faults.
SAM4 provides “direct electrical information, so you can catch electrical failures much earlier than you would using another physical signal such as vibration,” says Jasper Hoogeweegen, CEO of Semiotic Labs. “With both current and voltage data present, you gain the ability to track actual performance and efficiency metrics in real time.” SAM4’s capabilities contributed to Semiotic Labs’ recent partnership with Schneider Electric to provide asset health insights as part of Schneider’s EcoStruxure Asset Advisor platform.
The new ShaftAlign Touch laser alignment system from Prüftechnik enables maintenance organizations to upgrade to a digital system from decades-old legacy tools such as dial indicators and feeler gauges. It combines premium single-laser technology with Active Situational Intelligence software to empower users of varying experience levels to align standard assets with high precision and speed, explains Jonathan Gough, a Fluke Reliability product manager and the product owner for the Prüftechnik touch alignment platform.
Advanced motors and drives
Energy efficiency is built into today’s motor designs. The Baldor-Reliance EC Titanium from ABB is a ferrite-assisted synchronous reluctance (FASR) motor that can achieve efficiency levels above IE5. The integrated motor drive solution maintains high efficiency at any speed.
EC Titanium’s unique design “allows for excellent power density and synchronous speed operations with no loss in the rotor and lower losses in the stator,” says Mark Gmitro, global product manager for variable speed AC motors at ABB. “The motor is able to maintain efficiencies at lower speeds and partial loads with minimal bearing and winding temperature rises, and the design yields a power factor above 90 percent.”
