The seal failed and you replaced it. But it failed again and your seal supplier explained that the replacement seal you bought was a lower cost seal, and they have more expensive seals that might hold up better. So, you bought a more expensive seal, but it failed too. What went wrong?

Few things are less exciting in the motor world than a large synchronous motor that refuses to start—and all too often, the root cause is excitation. This article provides an overview of what synchronous motor excitation is, how it works, and the common issues you are likely to encounter.

Customers do not expect a salesperson to solve every technical issue on the spot, but they do expect a fast, informed response that demonstrates their problem is being taken seriously. EASA’s AI assistant, Eddy, can help close that information gap by quickly organizing technical questions, pointing to relevant EASA guidance, and helping the salesperson prepare a clearer response for the customer.

Time is your most valuable resource—yet most leaders struggle to manage it effectively. Discover practical tools and behavior changes that will help you achieve more with less stress.

While air-to-air cooled machines (WPII or TEAAC) dominate the market, water-to-air cooling is typical for motors rated above 5,000 kW (6,700 hp) or where water is readily available, or with specific applications such as wind generators. Service centers encounter two configurations: external tube heat exchangers and integral water jacket heat exchangers.

While there are mechanical concerns to consider as well, this article covers only the drying of the winding. The techniques listed here broadly cover stator windings, armatures, field poles, wound rotors and rotor poles.

Goals without action are just wishes. Learn the structured process that transforms aspirations into achievements and discover how to align your daily actions with your long-term vision.
