When preparing to rewind random or form-wound status, sometimes there just doesn’t seem to be enough room in the stator slot for the desired conductor area and insulation quantities. This presentation looks at balancing stator copper losses against insulation reliability.

As we communicate internationally, language barriers persist. In the technical fields, the metric-imperial units clash is slowly diminishing. Many vibration analysts are “bilingual” in that respect and are comfortable using either system. But for more casual users who may only encounter vibration data in regard to meeting specs, unfamiliar vibration amplitude units can be a challenge. 

See how 158 members responded to the Management Services Committee’s Pre-hire Assessment survey.

As a benefit of membership in EASA, we get (literally) an army of people every day to represent our interests in industry and government regulations. And they often provide us with valuable insight and positive change to “the way we’ve always done it.”

When repairing centrifugal and axial flow pumps, axial thrust is a concern. An understanding of the causes and the mitigating provisions of various pump designs will help repair technicians to ensure those provisions work properly.

Three of the most common three-phase motor problems we receive inquiries about are:

1. “The motor is drawing high no-load current.”
2. “The current of the three line leads is not balanced.”
3. “The motor is running hot.”

Even if you have never faced one of these issues, read on because it is almost inevitable that you will, and you will want to know what to do about it.

PCBs have been identified as a likely carcinogen for humans. If your service center is asked to pick up equipment that you suspect MAY contain PCBs, have it field tested BEFORE picking it up. Once you pick up a device that contains PCBs, the responsibility is yours.

This presentation addresses many of the most common safety hazards and situations that face service centers.

This video walks through the steps to adjust and set end play on a typical vertical hollow shaft pump motor.

One aspect of our repair industry that seems to cause a lot of confusion is the bearing arrangements of vertical motors. There is quite an assortment of thrust bearing arrangements, and we tend to try to apply the same method for adjusting end play to all of them. That is often a bad idea, so this article will take a closer look specifically at those fitted with a spherical roller thrust bearing and repair tips unique to these designs.
