Motor tester finds early faults


ALL-TEST PRO 31 electric motor tester performs a rotor test in less than 3 min, checks winding conditions to detect turn-to-turn or coil-to-coil faults early, determines phase balance, detects open windings, finds FDW or cable problems, and incorporates megohm meter with choice of 500 or 1000-V test and 0.00%%MDASSML%%500 MV range. Instrument works on ac and dc motors of virtually any size.

Meter detects broken rotor bars

CSMeter is a handheld instrument for online detection of broken rotor bars in squirrel-cage induction motors. Instrument provides on-the-spot diagnosis using advanced algorithms that guard against false indications. It is portable and requires only a current probe to clamp around one of the motor's main leads or around the secondary side of a main CT. Stores data for up to 29 motors.

Robot optimizes tight spaces

PowerScara is a compact, low-cost robot designed to fit into tight workspace configurations and to mount to existing station frame structure. Size of the controls has also been reduced to fit within a single slot of a 19-in. rack-mount cabinet. The drives/amplifiers are built into the robot arm, further reducing space requirements. Absolute encoder system eliminates need to reference.

Annual Salary Survey

After two years of economic concerns, manufacturing leaders once again have homed in on the single biggest issue facing their operations:

It's the workers—or more specifically, the lack of workers.

The 2017 Plant Engineering Salary Survey looks at not just what plant managers make, but what they think. As they look across their plants today, plant managers say they don’t have the operational depth to take on the new technologies and new challenges of global manufacturing.
