2-Day "Hands On" AC Drive Troubleshooting Seminar

One of the most common inquiries we get here at EMA Inc. is for training on AC Solid-State Motor Drives. Often it isn’t cost effective to teach on-site schools for a small # of people. Here is a VERY cost-effective solution. We’re offering a 2-day, intensive seminar on AC Drives (PWM). Who should attend? ANYONE troubleshooting, maintaining, applying or operating AC Drives.

You’ll leave this school with a clear & practical understanding of solid-state AC drives, motors and the mechanical/electrical interaction which takes place. You’ll learn to recognize classic drive trouble symptoms and quickly resolve common problems.

This seminar could easily return your investment with just one instance of reduced downtime due to your increased knowledge. An electronic background will be helpful, but not essential. We’ll review the basic electrical laws and component operation you need to know.
