FLUKE offers motor analyzer for testing motor performance without mechanical sensors

FLUKE Corporation is offering the Fluke 438-II Power Quality and Motor Analyser for a streamlined and cost-effective method for testing motor efficiency, while eliminating the need for external mechanical sensors and costly downtime. Using data from the motor nameplate coupled with three-phase power measurements, the 438-II calculates the real-time motor performance data including speed, torque, mechanical power and efficiency without the need for additional torque and speed sensors. The 438-II also directly calculates the motor derating factor in operating mode. It provides mechanical measurements (motor rotating speed, load, torque and efficiency) by applying proprietary algorithms to electrical waveform signals. The algorithms combine a mixture of physics-based and data-driven models of an induction motor.
