On October 22, 2018, the European Commission submitted its plan to expand motor and power converter efficiency regulations. As part of the EcoDesign directive, the Commission has been working on expanded motor and drive regulations for several years. The European Union directive will address both motors and variable frequency drives (VFDs) from .75 to 1,000 kW (1 to 1340 hp).

New IEEE standard provides guidance for motor protection for industrial and commercial applications

A review of major pump vibration standards

Working knowledge of standards helps members provide better customer service

  • July 2010

  • Article rating: No rating

Working knowledge of standards helps members provide better customer service. A quality repair in an EASA service center will yield a motor or pump that will meet just about any vibration specification. And good EASA technicians could use their "finger vibrometer" to verify that. However, a large number of EASA customers demand a more formal means of verifying acceptably smooth operation. A few sophisticated customers have developed their own vibration standards, but most depend on standards organizations such as the National Electrical Manufacturers Association (NEMA) (electric motors), the Hydraulic Institute (HI) (pumps) and the International Organization for Standardization (ISO). There are also industry specific standards organizations such as the American Petroleum Institute (API) for refineries and the Submersible Wastewater Pump Association (SWPA). A working knowledge of the various standards will be beneficial for EASA service center technicians and managers. The three examples in this article will help illustrate the scope and diversity of the various vibration standards a service center may encounter.

Guidelines for Maintaining Motor Efficiency During Rebuilding

  • November 2007
  • Number of views: 3918
  • Article rating: 5.0

The challenge for every motor repair firm is twofold: to repair the equipment properly, and to demonstrate to their customers by means of adequate testing and documentation that rewound motors retain their operating efficiency. Following the guidelines in this document will help you accomplish both.

To ensure that motors retain their efficiencies when rewound, EASA also strongly recommends that electric motor repair centers comply with ANSI/EASA Standard AR100: Recommended Practice For The Repair Of Rotating Electrical Apparatus and strictly adhere to the “DOs” and “DON’Ts” presented in this article. These guidelines, which contain safe values (based on available data) and correct procedures, apply to both energy efficient and standard motors. Further study of the matter continues, and these guidelines will be revised if additional information warrants.
