Kollmorgen has announced the new TBM2G series of frameless servomotors, introducing features that simplify the design of collaborative, surgical, aerospace and defense and other robots while delivering optimal performance in a lighter, more compact package. These new motors will complement Kollmorgen’s existing TBM and KBM series of frameless motors.
The mobile machine market encompasses equipment supporting the movement of materials and components. This includes agricultural machinery, construction vehicles, municipal machinery, etc. These non-road mobile vehicles—tractors, cranes, forklifts and material handling equipment—often require personalized solutions focused on machine safety, automation and electrification. Manufacturers today are merely scratching the surface when designing electric drive equipment for these challenging environmental applications.
Are you looking for one simple formula to help you choose between centralized and decentralized motor control? Unfortunately, such a formula does not exist. However, evaluating the overall size of the system, comparing labor and material costs, and maintaining flexibility can help guide engineers in the right direction.
Over the many years, there have been many technical papers and articles about which motor is the best. The short and sweet answer is - let's talk about the application. More
recently a number of papers and articles have appeared that compared each motor's advantages and disadvantages in generic or specific terms. Many times, the methods used to drive and control these motors are not completely described due to the many control schemes available for use. A few articles focus on just the open loop step motor and the closed loop servo motor advantages and disadvantages in a laundry list format. This article is attempting to "drill down" into the reasons why and to describe how it is done.
