Dynamically Adaptive Feed Drives for High Performance and Energy Efficient Manufacturing
Background and Motivation
Linear motors are used for fast and accurate motion delivery in a wide range of precision manufacturing machines. They however consume a lot of energy and generate a lot of heat in the process. In this project, we explore a mechatronic design concept where the electro-mechanical structure of linear motor driven machines is designed much like the power train of hybrid electric vehicles; i.e., their structure is designed to intelligently vary in real-time as a function of the manufacturing operation being performed, so as to simultaneously achieve high performance and improved energy efficiency. Two specific cases are studied within this project:
