EASA Senior Technical Support Specialist

One of the most frequent member requests to EASA’s technical support group is for the conversion of a 3 phase winding from concentric to lap. This presentation covers the important details for a proper concentric to lap winding conversion.  

Primary topics are the most common methods for concentric to lap conversion:

• “Rule of thumb”
• Concentric to lap conversion tables in EASA Technical Manual
• EASA AC Verification and Redesign (ACR) computer program
• Hand/manual calculation

This presentation is intended for winders, engineers, supervisors and managers. The content will be beneficial for beginners through highly experienced persons.
