Munich, Germany--Electric motors have undergone more change in the last ten years than the previous hundred. This is particularly true with ac induction motors. For example, users today can specify vector or inverter drives, as well as the convergence of both systems: sensorless vector control. Other emerging technologies include soft switching techniques and transient-resistant windings.
Computer models take over. Sensorless vector control blurs the distinction between inverter and vector drives. While open-loop inverters are relatively inexpensive, there is no method of feedback from the motor to allow
A new service lets engineers and orthopedic surgeons design and 3D print highly accurate, patient-specific, orthopedic medical implants made of metal -- without owning a 3D printer. Using free, downloadable software, users can import ASCII and binary .STL files, design the implant, and send an encrypted design file to a third-party manufacturer.
For industrial control applications, or even a simple assembly line, that machine can go almost 24/7 without a break. But what happens when the task is a little more complex? That’s where the “smart” machine would come in. The smart machine is one that has some simple (or complex in some cases) processing capability to be able to adapt to changing conditions. Such machines are suited for a host of applications, including automotive, aerospace, defense, medical, computers and electronics, telecommunications, consumer goods, and so on. This discussion will examine what’s possible with smart machines, and what tradeoffs need to be made to implement such a solution.
