Thank you for your registrations.

Objectives and Benefits

You are invited to attend this complementary seminar to learn how to overcome challenges in improving the accuracy of AC Machine Drive Designs, including Sensor-less Drives.

This course will show you how to use finite element analysis to gain deeper insight into the induced voltage and inductance required to obtain the rotation position.

You will discover how to achieve the most efficient motor drive systems, with a better understanding of the physical aspects that range from current and voltage to rotation angle.


“Advanced AC Drive Designs Using FEA to Achieve High Performance Control” is a free seminar that will provide you with a foundation in finite element analysis for the control of AC drives.

Those who will benefit:

• Motor design engineers
• Application engineers, especially for EV, HEV and, UAV Wind Energy
• Suppliers to motor manufacturers
• Control engineers
• Engineering and R&D managers
• Others who specify, design, analyze, manufacture or service IPM or BLDC machines

You should have some background in electric machine operation and construction such as the equivalent of a B.S. degree in engineering. Understanding of basic magnetic circuits is needed, but advanced motor theory and control techniques are not essential.
