On the tradeoffs between power density, efficiency and cost for high-performance, electric motors in choosing the most applicable technology for a specific application.
The industrial arts of mechanical engineering are all around us and seen in many forms and technologies. Of greatest interest is how these wonders are designed, constructed and used. From the smallest home appliance to the behemoths used for outsize building and excavation projects.
Motion control systems often combine high power drive signals in close proximity (or even within the same cable) with lower level signals, like encoders. You will often see ferrite beads added around cables; their effectiveness in minimizing noise is greatly affected by how they are deployed. This involves which signals are grouped, what are the drive characteristics, and how shielding and grounding are handled in the system.
Components like motors, bearings and drives are subject to harsh environments on Earth, but they must be at the top of their game to enjoy space travel. Recent applications from Maxon Motors (Return to Mars) and the University of Michigan (Robotic Legs) illustrate the incredible requirements it takes to handle applications in space and how these components can be utilized here on Earth.
Three-dimensional finite element analysis (FEA) simulation and research from published information is used to compare the features of various coil configurations.
