Over the past few decades, energy efficiency in motors has become an ever-increasing concern for OEMs and
manufacturers alike. With multiple
energy bills mandating higher efficiency across ever-broader spectrums of motors, including the most recent Small Motor Rule by the Department of Energy, efficiency has become an essential consideration when choosing a new motor.
One of the key challenges in the mining
industry today is maintaining throughput
in the face of ore grade quality that
has declined by 40 percent in the last
decade.
Enhancing production with — and for — less is the standing order in today’s manufacturing world. Speeding up production while at the same time looking for ways, to cut, for example, energy costs, is a tricky equation with no single answer; where and how management goes about achieving that can take several paths.
Hi. My name is Renee. I’m 12.
You might remember me from about a year ago, when my dad wrote about me and the home-made motor project we did together (“Make the Connection,” February 2014).

sales manager of Crouzet Motors
(Vista, CA), was bunkered
down in his office in Palatine,

ankle-deep snow from an unfortunately
terrible Chicago’s
winter night.
The use of motor current signature analysis (MCSA) for motor fault detection — such as
a broken rotor bar — is now well established. However, detection of mechanical faults
related to the driven system remains a more challenging task. Recently there has been a growing interest for detection of gear faults by MCSA. Advantages and drawbacks of these
MCSA-type techniques are presented and discussed on a few industrial cases.
