  • Article rating: No rating
Article

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.

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.

Crooked Teeth? We’ve Got Braces!

How Using Clamps When Pulling Magnet Wire Helps Prevent Splayed Teeth

  • January 2024

  • Article rating: No rating
Article

Unless great care is taken, pulling magnet wire from a motor stator often bends or splays the lamination’s end teeth. Bent teeth, or teeth that have been splayed outward at the ends of the core stack, will likely compromise the quality of the repair job. Therefore, we have designed and implemented the use of disc clamps to hold the stator tooth tips in place while pulling magnet wire from the slots. The clamping fixtures described in the photos have helped ensure that we avoid damaging the stator teeth during the stripping process.
