Directional input and tachometer output signals are included. The bulletin also charts electrical interface and diagrams a typical connection. To get a copy, visit www.pennmotion.com.
Researchers working with additive manufacturing have said multimaterial techniques will allow industry to fabricate materials with combinations of density, strength, and thermal expansion that do not exist [yet].
The term "multiphysics" is used to describe the simulation of multiple types of physics and their influence on one another -- for example, the investigation of the behavior of a chemical in liquid form will involve both chemistry and fluid dynamics.
