​How It All Started

ESW was founded by Al Naegeli in the basement of his home in 1972. 

A neighbor mentioned that the motor industry needed a better way to test armatures, and Al began working on developing a test system for armatures. He worked  closely with a local customer and delivered it later that year with great success. Word quickly spread and ESW was off and running. A short time later, ESW rented space in a manufacturing building.  By 1976, the company built its own facility in order to house both manufacturing and offices in one space. Within a few years, an addition was needed to accommodate ESW' s rapid growth. 
Over the years, ESW has been known as a leader in the industry. ​We revolutionized armature testing by electronically scanning the armature. This eliminated the need for an operator or machine to rotate the armatures. ESW also introduced weld testing to the market, as well as masterless testing. ESW was also among the first to computerize the testing process. In the early 1980’s, we introduced the first fully computerized armature tester to the market which utilized an RCA computer system.  In 1992, the company moved the test platform to a PC based computer system. At the same time, a bold move was made to standardize the platform for both armature and stator testers. This meant that customers could share numerous spare parts and the trouble-shooting capability on both systems. In 2000, ESW introduced its first Windows based tester. An effort was made to use as much of the previously proven hardware, while moving to the Windows system so that upgrade compatibility could happen for aging systems. 

After leading ESW for 30 years, Al Naegeli retired in 2002. Tim Naegeli and Linda Naegeli took over ownership, management, and direction of the company. With the change in leadership, Tim and Linda recognized the need to look outside of stator and armature testing as their core products.  New efforts were put into developing motor test systems, noise and vibration systems, and wire bonding systems.   
​
​We continue to advance our technology as we work in close collaboration with our customers. ESW manufactures standard as well as highly customized test systems. We continue to explore industry needs and expand outside of the motor industry where we can apply our expertise to meet other testing and automation needs.
