Vertical Motor Operation and Repair

June 2020
Convention presentation

Vertical motors differ from horizontal motors in numerous ways, yet some view them as “just a horizontal motor turned on end.” The obvious differences are the (usually) thrust bearings, with arrangements varying from single- to three-thrust bearings with different orientations suited for specific load, rpm and applications. Less obvious differences are in the ventilation arrangements, shaft stiffness, degrees of protection and runout tolerances. This recording will cover those topics.

Can Premium Efficient Motors Be Rewound without Degrading Efficiency?

June 2020
Convention presentation

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 Testing of AC Stator Windings

July 2019
Convention presentation

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.

Case Studies in Failure Analysis

July 2019

June 2018
Convention presentation

The paper "Air Gap: What Is It, What Does It Do, and Why Is It Important?" presented by Chuck Yung at the EASA Convention 2018 explores the critical role of the air gap in AC and DC machines. The air gap is the physical space between the rotor and stator in AC machines, or between the armature and fields/interpoles in DC machines. This gap is crucial for the machine's magnetic performance and efficiency.

How the ISO 21940-11 Balance Quality Grade Standard Impacts Service Center Balancing

June 2018
Convention presentation

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.

Induction Motor Rotor Windings

June 2017
Convention presentation

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.

Requirements to Service Hazardous Location Motors

June 2017
Convention presentation

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, Techniques & Cautions

June 2017
Convention presentation

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.

Emerging Technologies in the Motor Industry

June 2017
Convention presentation

The paper "Emerging Technologies in the Motor Industry" by Tom Bishop, presented at the EASA Convention 2017, explores the potential successor technologies to the squirrel-cage induction motor. The focus is on permanent magnet (PM) motors, reluctance motors, and other emerging motor technologies that are nearing commercial reality. Bishop begins by acknowledging that while the induction motor will remain prevalent for decades, newer technologies are gaining traction.
