EASA Accreditation Program

It has been proven that electric motor efficiency can be maintained during repair and rewind by following defined good practices. EASA has developed an international accreditation program for service centers based on the sources of these good practices. The intent of this groundbreaking accreditation program is to evaluate service centers for evidence of compliance to assure that they are using prescribed good practices to maintain motor efficiency and reliability during electrical and mechanical repairs of electric motors. Repair processes that will be audited include rewinding, core testing, bearing replacement, bearing journal rebuilding, dynamic balancing; and electrical testing, mechanical measurements and calibration. This webinar session will provide insight into the EASA Accreditation Program and the third-party audit process that is an ancillary and key component of it.

Who should attend

This seminar will be most useful for service center supervisors and managers. The content will be beneficial for entry level supervisors through managers and owners.

Topic(s): AC, DC, Repair tips/procedures, Sales, Marketing & Management

Evaluating High No-Load Amps of Three-Phase Motors

Have you ever had to deal with a rewound motor that had high no-load amps? That is almost a rhetorical question as most of us have experienced this situation. The focus of this session will be on the steps to take before rewinding, to avoid the undesirable situation of high no-load motor amps after the rewind.

Our focus will be on the following steps that should be performed on every AC stator rewind:

  • Inspect the stator bore and rotor outside diameter for evidence of machining or damage
  • Record the original winding data exactly as found
  • Verify the winding data
  • Test the stator core before and after winding removal
Who should attend

This seminar will be most useful for service center mechanics and winders with any level of experience, and service center supervisors and managers.

Topic(s): AC, Theory & design

Final Testing for Pumps - An Overview

The pump repairs are completed! Now the pump needs to be tested. This webinar will discuss the procedures for the basic tests that can be performed on pumps that have been repaired in the service center.

Final testing of pumps can include:

  • Operational Tests
  • Seal Leakage Test
  • Motor Chamber Leakage test (submersibles)
  • Casing Pressure Test

While some of these tests are not difficult to perform, knowing the methods and limits will help service centers to confidently deliver quality pump repairs.

Topic(s): Pumps, Testing

Final Testing of DC Machines

To assure a quality repair, there are specific tests (such as neutral-setting and interpole-armature polarity) that should routinely be performed on every DC machine. When done correctly, the simple procedures presented in this session will prevent scenarios such as that late night phone call from an irate customer whose DC machine is “arcing like a fireworks show.”

Who should attend

Technicians with at least a moderate level of experience in DC machine repair will benefit from this session.

Topic(s): DC, Testing

Fundamentals of Shaft Alignment

Automatic alignment instruments are no substitute for understanding the underlying process of aligning direct coupled machines. This webinar will explain the simple calculations that govern the alignment process. That understanding will allow technicians to use any alignment tool more effectively, and deal with issues that confound the process.
