Design Electric Machines with SPEED

April 11 – April 15, 2016               Magsoft Corporation, Clifton Park, NY

This training session is for people involved in the design and manufacturing of electric motors and generators. It can be an initiation course as well as a refresher course. The goal of this session is to learn how to design electric machines with SPEED and how to leverage the full power of SPEED to optimize your designs for sustainable development.

Tan PhamThis is a 4.5 day training session. It covers multiple types of machines.

Participants may choose to attend the full session (4.5 days) or specific sessions. Sessions start daily at 9:00 AM and end at 5:00 PM. Session on last day (half day) starts at 9:00 AM and ends at 1:00 PM

This course provides hands on experience. Participants will have SPEED installed on their computer for the duration of the course. Extended evaluation period of SPEED will be provided on request.

This course is lead by Dr. Tan H Pham
