Intro to Low-Cycle Fatigue Testing for Electric Motors

Leave a Comment

Regarding material and machine components, the term “fatigue” refers to cracking or fracturing in an object caused by stresses that are within its operational envelop, and often within its elastic range. These cracks and fractures grow, and they can eventually lead to a failure of the component and damage or destruction to the greater assembly […]

How To Avoid Major Causes of Unbalanced Parts?

Leave a Comment

Unbalanced components can lead to electrical motor failures that necessitate costly investigation, repairs, or replacement. The easiest way to avoid this is to properly balance the rotor during the manufacturing stage. Unbalance happens when a rotating component’s center of mass, or inertia axis, becomes unaligned with its center of rotation, or geometric axis – It […]

Why Partner With Test Devices for Your Overspeed Spin Testing Needs?

Leave a Comment

Spin testing is a critical step in the manufacture of rotating components. While some original equipment manufacturers (OEM) may have the resources to perform these testing operations in-house, many do not. As such, they have to outsource these operations to a third-party spin testing service provider. Unfortunately, this option increases the potential for tight timelines […]

What Is Rotor Balancing and Why Is It Essential?

Leave a Comment

Rotors are a critical component used to convert electric or electromagnetic energy into rotational motion. For rotors to operate reliably, they must maintain even weight distribution across the rotational axis. Too much weight on one side creates uneven mass distribution known as “unbalance”. Rotating parts in any mechanical assembly can become unbalanced. Uneven weight distribution […]
