With internal permanent magnet motors, the high frequency signal injection method can deliver precise speed control without the need for a feedback sensor.
Tailoring motor speed to the task offers a variety of important benefits. One page article published in October 2011 issue of Chemical Processing magazine.
Yaskawa America, Inc. - Drives & Motion Division is changing the way in which it manufactures its drives. The company is beginning with a new assembly process for the V1000-series ac micro drives. Production equipment being installed this fall will contain more automation, including MOTOMAN robotics. The drives will be manufactured by robotics cell production, a process capable of producing three million units per year. That's more than a 50% increase compared to traditional methods. Additionally, they meet the regional needs of Europe, North America, and Asia.

Understanding the benefits of IEC61131-3 and why its programming methods are becoming preferred for mechatronic designs. Written by Matt Pelletier and published on DesignNews.com in April 2011.
There are well-known benefits of using variable-frequency drives (VFDs) to reduce energy consumed by induction motors. Federal, state and local agencies in the U.S. now all give incentives for installing VFDs, as do many utilities. The energy saved by using VFDs can be compelling, and taking advantage of these programs can add considerably to their savings.
One of the most beneficial ways to increase efficiency and lower energy costs in a cooling tower design is to utilize a variable frequency drive (VFD). This article will discuss the different aspects of designs in which VFDs are used to improve performance and how this performance differs from conventional cooling tower designs.
As published in the January 2011 issue of HPAC Engineering, this case study discusses reducing energy cost, maintenance, noise, and vibration at the University of Rochester utility cogeneration plant using Yaskawa variable frequency drives.
