Reclosure: How It Happens and What To Do About It

Reclosure occurs when power to a motor is briefly interrupted and restored before the magnetic field has fully collapsed in the motor’s winding. If this occurs while the applied power is out of phase with the collapsing field, significant damage can result. This session will address how this can happen and what measures can mitigate damage potential. It will include:

  • Reclosing a switch or breaker before the magnetic field collapses
  • Utilities’ automatic reclosure
  • Contactor “chatter”
  • Determining the time constraint
  • Remedies: Time delay; Zero crossing


Repair Best Practices to Maintain Efficiency

There are certain repair processes, such as winding removal and replacement, that can impact the efficiency and reliability of electric motors. Prudent repair practices must not increase overall losses, and preferably should maintain or reduce them. This session will explain how those repair processes affect efficiency and reliability; and presents the best repair practices in order to maintain or improve efficiency.

Root Cause Failure Analysis Methodology

Root Cause Methodoloy is a step-by-step method for examining a failed motor and its system. It focuses on the stresses that acted upon the failed component. By better understanding these stresses, the service center is more likely to uncover the root cause of failure.

This webinar will examine the five key steps of root cause methodology:

  • Failure mode
  • Failure pattern
  • Appearance
  • Application
  • Maintenance history

The webinar will also discuss the "5 Whys?", summarize motor stresses, and stress the importance of total system analysis (not just motor).

Who should attend

The webinar will be most useful for service center and field technicians, service center managers, engineers, and users maintenance personnel desiring to understand the techniques for determining root cause of failures and implement remedies to improve reliability.

Topic(s): AC, DC, Root cause failure analysis

Squirrel Cage Rotor Testing

Determining whether or not a squirrel cage rotor is defective is an issue that is a challenge to every service center as there is often no simple way to determine the integrity of a rotor. The primary focus of this session will be to describe many of the available tests that can be utilized in the service center or at the motor installation site. In addition to conventional squirrel cage rotor testing methods such as the growler test, techniques that will also be covered are the use of a core loss tester, high current excitation, and spectrum analysis of vibration.

Who should attend
This webinar will be most useful for service center and field technicians with at least 2 years experience, service center supervisors and managers, engineers, or anyone with previous experience dealing with suspected open rotor issues.
Topic(s): AC, Testing

Strength and Characteristics of Motor and Pump Shaft Materials
