Wound Rotor Motor Fault
Wound rotor motors, theoretically they are the same as far as induction. The access to the motor is significantly increased with round rotor motors and it allows an interesting trouble shooting approach.
Keeping Out Environmental Contaminants
In dusty or wet vibration monitoring applications, sealing of the sensor itself as well as sealing of the cable to the sensor is of prime importance in order to avoid contamination of the signal. But how sealed is it? Is there a way to quantify “sealed”?

Ultrasound Assisted Lubrication
Improper bearing lubrication is responsible for several issues, such as increased lubricant usage, increased bearing purchases (due to failures), increased equipment failures, increased operating temperatures, and motors that run inefficiently.

Vibration Measurement Techniques for Continuously Varying Speed Machinery
There are a lot of equipment types in industry that exhibit continuously varying speed. This presents a number of challenges to the vibration analyst. If a time sample is collected as the machine is continuously changing speed, the FFT will produce a virtually useless plot...
