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.

Motor sophistication, precise torque and speed control and accuracy are all common­place in the manufacturing environment today. They are not just reserved for the aerospace or machine tool industry. 

With modern processes in manufacturing we need to know and control the speed, position and velocity of electric motors. With this precision comes the need for feedback in these areas. 

Servo, closed loop vector, brushless DC, standard DC mo­tors and standard three-phase AC motors use feedback devices such as encoders and resolvers. Many AC and DC motors have the feedback device mounted on the exterior of the opposite drive endbell, mechanically attached to the rotating shaft. Servo, vector and brushless DC motors usually have an encoder or resolver mounted inside the endbell as an integral part of the equipment.
