In 2003, EASA and AEMT (Association of Electrical and Mechanical Trades in the UK) issued a report that proved rewinding motors in accordance with prescribed good practices would maintain efficiency and reliability. But in recent years, claims abounded that premium efficient motors could not be rewound without degrading efficiency. This recording discusses the latest EASA/AEMT research that included independent, third-party testing.

High-potential (hipot) testing is a critical method used to evaluate the ground insulation of AC stator windings. This testing is performed during various stages, including in-process, after rewinding, and post-delivery. The primary objective of hipot testing is to ensure the insulation's adequacy against breakdown under normal operating conditions. The paper discusses the differences between AC and DC hipot testing, emphasizing the importance of sizing AC test sets appropriately when testing large windings. It also covers relevant standards, the communication of test requirements, the timing and levels of testing, and the evaluation of results.

The paper "Case Studies in Failure Analysis" by Chuck Yung, presented at the EASA Convention 2019, delves into the methodologies and practical examples of root cause failure analysis (RCFA) for electric motors. Yung emphasizes the importance of understanding motor design, application, appearance of failure, and operating environment to accurately diagnose motor failures. While extensive investigations are necessary for critical motors, less critical motors can often be assessed using experience and common sense.

The internet is exceptionally good at one thing – providing data access. Similarly, computers which are the heart of the internet are good at dealing with data; they store data and analyze data. With the access to data provided by the internet and the storage and analysis capabilities of computers, results are possible now that could only be dreamed about in the prior century, (even if some of those dreams were nightmares).

The paper "Overview of the New Shaft Alignment Standard" by Gene Vogel, presented at the EASA Convention 2018, introduces the ANSI ASA S275 Part 1: General Principles, Methods, Practices, and Tolerances standard for shaft alignment. This standard was developed by the Vibration Institute in collaboration with the Acoustic Society of America (ASA) to provide a comprehensive and consistent approach to shaft alignment across various industries. Prior to this, there was no national or international standard for shaft alignment, leading to inconsistencies in methodologies and tolerances.

The paper "How the ISO 21940-11 Balance Quality Grade Standard Impacts Service Center Balancing" by Gene Vogel, presented at the EASA Convention 2018, discusses the implications of the updated ISO 21940-11 standard on balancing practices in service centers. The ISO standard for balancing tolerances, previously known as ISO 1940-1, has undergone revisions, with the most recent change renaming it to ISO 21940-11. This standard establishes Balance Quality Grades based on rotor mass and maximum operating speed, defining the permissible residual specific unbalance, which, when multiplied by angular velocity, produces the Balance Quality Grade number.

In his paper presented at the EASA Convention 2018, Gene Vogel explains the fundamentals of pump curves and affinity laws in a straightforward manner, aiming to demystify the relationship between pump performance and motor load. Vogel begins by highlighting the differences between electric motors and pumps, noting that while motors adapt to load changes through flexible magnetic fields, pumps require changes in rotating speed or impeller diameter to adjust to flow requirements.

Presented at the 2018 EASA Convention in Milwaukee, WI, this presentation takes a deeper look into the data from EASA's latest industry research project.

Three-phase induction motors, which are fundamental to numerous industrial applications, feature either squirrel-cage rotors or wound-rotors. Squirrel-cage rotors are prevalent due to their robustness, reliability, and cost-effectiveness, while wound-rotor induction motors, though less common due to advances in power electronics and variable frequency drives, are still used in applications such as cranes, hoists, and mills. This paper explores the construction and operation of both types of rotor windings in three-phase induction motors.

Hazardous location motors, often referred to as explosion-proof motors, are designed and tested for use in environments where fire or explosive hazards may exist due to flammable gases, vapors, combustible dusts, or ignitable fibers. These motors must contain any flame within the motor to prevent ignition of the surrounding atmosphere. Various standards govern the use of these motors, including those from Underwriter’s Laboratories (UL), Canadian Standards Association (CSA), International Electrotechnical Commission (IECEx), Mine Safety and Health Administration (MSHA), Factory Mutual (FM), Atmosphères Explosibles (ATEX), and British Approvals Service for Electrical Equipment in Flammable Atmospheres (Baseefa).

Field service work can be challenging due to unfamiliar surroundings, potential hazards, and the lack of usual tooling. Chuck Yung's paper "Field Service Work, Techniques & Cautions," presented at the EASA Convention 2017, provides valuable insights into making field service work easier and safer. Yung emphasizes the importance of personal protective equipment (PPE), including Nomex clothing, steel toe footwear, hardhats, safety glasses, and goggles. He also highlights the necessity of lock out, tag out procedures to ensure safety when working on equipment that might start unexpectedly.

Yung emphasizes that small improvements can yield significant benefits without requiring substantial investments.

The paper "Isolation Test Bed Design and Construction" by Gene Vogel, presented at the EASA Convention 2017, provides a comprehensive guide to designing and constructing test beds for vibration testing of electric motors and generators. EASA recommends compliance with the vibration standards in NEMA MG1-Part 7 for new and repaired machines, which are tested with no load and uncoupled. Machines can be resilient mounted, rigid mounted, or set flat unsecured for vibration testing. Resilient mounting involves setting the machine on durometer pads to isolate it from the supporting structure, while rigid mounting requires a stable test bed.

In his paper presented at the EASA Convention 2017, Gene Vogel provides an in-depth overview of mechanical seals used in centrifugal pumps, highlighting their importance, design, and common issues. Mechanical seals are crucial for preventing liquid from escaping where the shaft enters the pump housing. They consist of two main components: one attached to the shaft and one to the pump housing, each with extremely smooth mating seal faces held together by mechanical and hydraulic pressure.

In his paper presented at the EASA Convention 2017, Gene Vogel discusses the advantages of using variable-speed drives (VSDs) to enhance the efficiency of pump systems. Vogel begins by contrasting the sizing of electric motors and centrifugal pumps, noting that while a larger motor on a smaller load runs efficiently, a larger pump on a smaller load can lead to inefficiency and increased energy consumption. Motors convert electrical power into mechanical power, while pumps convert mechanical power into hydraulic power, with each conversion involving some energy loss primarily to heat.

The paper "Speed/Torque Curves" by Jim Bryan, presented at the EASA Convention 2016, delves into the fundamental principles of torque in electric motors, particularly focusing on squirrel cage induction motors (SCIM). Torque is the force that produces rotation, and the primary function of an electric motor is to convert electrical energy into mechanical energy to perform tasks. The paper explains how torque and load interact, emphasizing Newton's third law, which states that for every action, there is an equal and opposite reaction. When the torque produced by the motor exceeds the load torque, the system accelerates until equilibrium is reached.
