This 1-day variable frequency drive seminar is designed to introduce the attendee to AC drive systems including theory of AC drive operation and proper motor selection. The student is introduced to concepts of variable frequency adjustable speed control and AC motor theory. Typical applications are discussed along with common pitfalls.This is an excellent seminar for electrical designers, plant engineers, supervisors, and sales staff involved in specifying AC drives or electric motors to be used in conjunction with AC drives

Get answers to questions like:

• How does a VFD work ?
• What are the different types of VFDs and how do I decide which one is best for my application?
• Is there really such a thing as an "Inverter Duty" motor and what is special about it?
• Can I use a "standard" 60 Hz motor with an AC drive?
• Why should you always avoid use of "high efficient" motors with AC drives?
• Why are NEMA "Design A" motors a bad choice when used with AC drives? Which motor design is best?

Learn how to successfully gain 50% additional motor torque, without any additional amperage, by replacing an 1800 RPM motor with a 1200 RPM motor AND still achieve at least 1800 RPM from the 1200 RPM motor (or even more).

Topics include:

• Evolution of adjustable speed drives
• AC & DC electrical terminology
• AC motor theory
• Choosing the correct motor
• AC drive (VFD) theory
• AC drive terminology
  
• Properly matching a drive to a machine
• Benefits of over-speeding motors
• Typical application mistakes and pitfalls
