Doing Our Part: Test Devices’ Community Outreach

Leave a Comment

Test Devices is a business unit of Schenck USA Corp.; we perform engineering tests, and we also have outsourced production services at our other Hudson location. In early August, we welcomed a group of students from Brockton High School. As a part of their summer program, the students visited Test Devices to learn what we […]


Green Mobility: The Mobility of Tomorrow

Leave a Comment

While the COVID pandemic has posed significant challenges worldwide, it also created an opportunity for us to slow down and reflect on vulnerabilities and inefficiencies in many areas of our social and economic structures. One of the concerns is our efforts towards sustainability, especially in regard to transportation. Dramatic reduction in transportation traffic during the […]

How to Eliminate Noise and Vibration From eVTOLs?

Leave a Comment

Noise, vibration, and harshness (NVH) is a key concern that influences driver and passenger experience in the automotive industry. NVH is a challenging quality to engineer because it is subjective from person to person, as well as the context of the passenger experience. NVH is also an important topic for the aerospace industry. Not only […]

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 […]
