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

Zoom logo

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.

Internal Connection Diagrams coverPublished: August 2006 & Revised: January 2023

This edition of EASA Internal Connection Diagrams contains significantly more connections and winding diagrams than the previous version (1982), as well as improved templates for drawing connection diagrams. It provides internal connection diagrams for three-phase windings. It can be used with either concentric or lap windings. It also covers all possible parallels; wye and delta, 2 - 48 poles; part windings; two-speed windings; wye-delta and consequent-pole connections, 2 - 48 poles. It includes PAM connections, as well as triple- and quadruple-rated connections.

In terms of the number of connections, this edition covers more poles than before. It also now contains some less-common connections. These include the European pole amplitude modulation (PAM) design; multi-torque ratings; and part-salient, part-consequent pole connections that permit pole/slot combinations that otherwise would be unattainable.

Although the “by-the-numbers” method of drawing connections remains basically unchanged in this edition, the winding connection templates have been greatly improved. New templates for skip-pole and adjacent-pole diagrams also have been added to simplify drawing these connections. The jumpers are shown in gray with different line patterns for each phase. 

The book also includes templates for 2-pole through 30-pole, adjacent (1-4 jumpers) and skip pole (1-7) connections.

A printed version of this book is available for purchase in the online store.
