ABB Designs Latest Device to Bridge Gap Between General Purpose and Heavy-Duty Motors

June 03, 2021 by Alessandro Mascellino

ABB has expanded its motor line with the addition of the Baldor-Reliance Severe Duty XT Motor.

The device has been designed to bridge the gap between ABB’s Baldor-Reliance General Purpose and the company’s XEX premium severe duty motor lines. The Baldor-Reliance Severe Duty XT Motor is already available for distribution on ABB’s website.

Heavy-Duty Applications

Severe Duty XT Motors are ABB’s range designed to tackle challenges in the most severe duty application. 

The motors in this category feature easy installation and maintenance procedures and a series of comprehensive standard features designed for equipment protection and performance.

"When it comes to performance, the Severe Duty XT is a versatile option for what the industry expects as severe duty,” said Matt Rodebush, ABB NEMA Motors Global Segment Manager, commenting on the release of the new devices.

In terms of applications, the new motors are designed for several common industries, including chemical, oil, & gas, pulp & paper, metal, foundries, and more.

“With Baldor-Reliance Severe Duty XT motors, premium features come standard on a wide variety of configurations. Therefore, it’s easy to get up and running with a high-performance motor for the most demanding applications," Rodebush added.

The Baldor-Reliance Severe Duty XT Motors feature a heavy-duty cast-iron frame construction available from 1-300 HP NEMA 143T frame and up to 449T. The devices also offer enhanced ingress protection and corrosion-resistant two-part epoxy paint for durability. It also provides color lead cables designed for easy identification and installation.

To facilitate connecting, the motors’ rotatable conduit box is both diagonally split and oversized. The motors are also designed to provide increased mechanical rigidity and a greater level of insulation between phases, so their phase paper and coil head lacing on each winding turn.

Other features of the new motor include a laser-etched inverter-duty nameplate​, sealed bearings on 143T-256T frames to provide a reduced need for maintenance, and compatibility with the ABB Ability smart sensor software.

The Baldor-Reliance Severe Duty XT Motor is also dynamically balanced to achieve vibration levels below NEMA requirements ​and comes with a three-year warranty.


A “Uniquely Suited” Motor

According to the product datasheet, the company refers to the Baldor-Reliance Severe Duty line as “uniquely suited for every rugged application.” The family of motors includes several components designed for different types of heavy-duty applications and offering very different features.

For example, while most of the Baldor-Reliance motors meet or exceed all efficiency requirements for the US, Canada, and Mexico, the RPM XE can achieve up to four levels above NEMA premium standards. While the Severe Duty XT and most other motors feature NEMA Design B torques as a minimum, the Crusher Duty features a NEMA Design A, a high torque design exceeding Design C.
