When an electric motor experiences performance problems or fails prematurely, the cause can frequently be traced to an incorrect voltage specification. Avoiding these errors is easy if one simple rule is followed: Rated motor voltage should be slightly lower than rated transformer (distribution) voltage.
Decatur Industrial Electric has added another lathe to our shop floor.
38″ swing x 157″ long.
There are various technologies that can test a motor while running, including:
Curious on how often you should test?
On-line testing with motor relays is a continuous 24/7 device.
Off-line testing frequency will depend on the atmosphere the equipment is in. It can be done more often if tracking a deterioration situation.
How do we know when the stator is going to fail? To find out what is going on with the stator, Decatur Industrial offers offline condition monitoring which does resistance to ground, phase to phase resistance, and polarization index.
Brett Kunzman will start his new role tomorrow, March 1, 2017, but he is not new to Decatur Industrial. He has been with us for 19 years. A Decatur native, Brett started with us shortly after his high school graduation, where he also attended vocational school and got outside experience working in production and maintenance.
Brett has worked in various areas for the company, including machining, disassembly and assembly, and field service and technical maintenance.
He has completed numerous trainings and holds various certifications:

The Potential to Failure Curve (or P-F Curve) gives the user information on how an asset behaves before a failure occurs. This example is focused on failure due to misalignment. The goal of a reliability focused plant is to be as far to the left on the curve as possible. While some companies are doing predictive maintenance work in an effort to reach the left side, many companies today are on the right domain of the curve, doing reactive work. Being in the reactive domain—putting out fires as they say— increases maintenance costs. This forces a company to perform unplanned work, causes unscheduled downtime, and higher costs to expedite parts. Using technologies like ultrasound, thermography, and vibration analysis will catch an asset in a pre-failing state. This allows time to plan and schedule the repair to take place. However, with the right processes in place, the technician should recognize the misalignment of the machine before it causes components to fail. The ultimate goal is to be so far left on the curve, that it is off the chart, at the point where all the efforts (flat and rigid bases, accounting for thermal growth, eliminating soft foot, precision alignment, etc) are made so that the machine never runs misaligned.
