Implications of NFPA 70E and 70B to Field and Shop Operations
This presentation provides a practical overview of applying both NFPA 70E (electrical safety) and 70B (electrical maintenance) standards to field and shop operations.
Maximizing Value from EASA’s AI Assistant: Effective Prompt Engineering for Success
Knowing how to interact with Eddy can dramatically improve your results with technical questions, troubleshooting and documentation resources.
Three-phase Motor “Rules of Thumb”
Often when we are dealing with three-phase squirrel cage motors we ask ourselves “Is there a standard or a rule of thumb for this motor characteristic?” The 10 characteristics that follow apply to conditions associated with motor starting as well as steady state operation. Examples are provided for each of the characteristics.
Consider Establishing a Roving Chief Executive Group
You’re Likely to Discover the Benefits Outweigh the Energy Expended
We all need friends, right? Isn’t the world a better place when you have someone to share it with? Electric motor shop leaders are no different. Peer groups have long been known as a means by which to advance collective goals and performance. EASA’s Roving Chief Executive (RCE) groups are exactly that - tailored to the executive, owner or general manager of electromechanical repair facilities.
Induction Motor Rotor Windings: Squirrel-Cage and Wound Rotor Basics for the Technician
This presentation covers induction motor basics for squirrel-cage and wound rotor motors.
Introducing IEEE 2455: DC Repair Standard
IEEE Recommended Practice for the Repair and Maintenance of Direct Current Electric Machines
There is now a much-needed DC repair standard, created through the participation of EASA members and industry motor users.
Measuring Up: How a Coordinate Measuring Machine (CMM) Helps Catch Costly Motor Problems Before They Escalate
When repairing electrical apparatus of any type, a common task is to ensure that machined fits are within acceptable limits of Geometric Dimensioning and Tolerancing (GD&T). The complexity of the task, of course, adds time, and time is never in surplus at a motor service center. Skipping these GD&T checks to save time can lead to mistakes and failures, with costs ranging from a few days of additional work to complete motor replacement and possibly lost production time for both the customer and the service center.
Vertical Motor End Play
This recording provides an overview of common different thrust bearing arrangements, with end play guidance tips for each.
Rewind Tips for Two-speed, Two-Winding Hoist Motors
Concentric to lap winding conversions are common practice in many EASA service centers. For most stators, this change is feasible and can be made with little difficulty. In some cases, however, it can be quite challenging and result in undesired outcomes due to reduction in copper or insulation.
Explain What You Do and Why That Matters to Your Customer
Effective industrial marketing isn’t about listing services—it’s about solving problems. This brief article explores how shifting your message from offerings to outcomes can better connect with customers and position your company as a true partner in reliability.
