The market share and usage rate of linear motors are increasing, partly due to the end users needing higher throughput and higher accuracy. The understanding of linear motors is usually that they can run at high speed, have long travel and high positioning accuracy, which other driving mechanisms cannot achieve. However, in fact, the advantages of ...
