How a webinar works

All EASA private webinars are live events in which the audio and video are streamed to your computer over the Internet. Prior to the program, you will receive a web link to join the meeting. 

The presentation portion of the webinar will last about 45 minutes, followed by about 15 minutes of questions and answers.

Requirements

  • Internet connection
  • Computer with audio input (microphone) and audio output (speakers) appropriate for your size group
  • TV or projector/screen

The Zoom webinar service EASA uses will ask to install a small plugin. Your computer must be configured to allow this in order to have full functionality. Please check with your IT department or company's security policy prior to scheduling a private webinar.

Private Webinars

EASA's private webinars are an inexpensive way to bring an EASA engineer into your service center, place of business or group meeting without incurring travel expenses or lost production time.

Interpole strength: Determining correct number of circuits

We have a DC motor that arcs when loaded. We checked all the usual suspects: brush neutral, interpole polarity relative to the armature, brush spacing around the commutator, etc. How can we determine the correct interpole circuits? 

I’m excited to be able to share a brand new DC repair tip. A conversa­tion with two EASA members led to a method for determining whether the interpoles are connected with the correct number of circuits. 

Not only is this new method easy, it’s a refinement of the interpole polarity test we routinely perform on every repaired DC machine. To explain why this method works, let’s review some design basics and then use that information to determine the correct interpole circuits.
