Siemens' Micro Master Vector and Midi Master Vector Variable Frequency Drives (VFDs) are reportedly the first to integrate sensorless vector control into the small dimensions of a standard frequency controller. The two units are smaller in size and offer more standard features than their VFD predecessors. They are also compatible with standard induction motors ranging between 1/6 to 100 hp. Introduced in 1993, the Micro/Midi Master drives were among the first VFDs to offer breakthrough technologies, such as flux current control for automatic current load adaption. In their latest iteration, the controllers' sensorless vector inverter capability derives from a new ASIC that quickly calculates rotor speed and position. This enables the rotor and stator current to be controlled for optimized performance. Siemens Energy & Automation Inc. Product Code 4362 (P)
As manufacturers add new technologies to their products, designing for compliance becomes more difficult. Prepare for the certification testing process. Otherwise, you increase the risk of discovering a safety issue after a product leaves the assembly line. That will cause significant time-to-market delays, be much costlier to fix, and damage your brand in the eyes of customers.
Stratasys will be exhibiting two groundbreaking large-scale additive manufacturing technologies, as well as other new products, next month at the International Manufacturing Technology Show (IMTS) in Chicago.
Two new technologies from Stratasys, created in partnership with Boeing, Ford, and Siemens, will bring accurate, repeatable manufacturing of very large thermoplastic end products, and much bigger composite parts, onto the factory floor for industries including automotive and aerospace.
