Rockwell Automation Fair Technical Session
Wednesday, Nov 9 at 2 p.m. and Thursday, Nov 10 at 2 p.m.

Many companies are considering use of permanent magnet motors rather than induction motors, because of permanent magnet motors offer energy savings higher power densities, and improved control.  They do come with a higher upfront cost, but many customers have found that the total cost of ownership may be lower.

Because of these added costs, it is imperative that companies do everything to protect their investment.  Wayne Walcott, application engineer with MTE, will discuss ways to protect motors from power distortion, harmonics, and overheating, which often are caused by the variable frequency drives, which are required to start and operate a permanent magnet motor.
