Design of Movable Component for Ultrahigh Acceleration and High Speed Linear Motor
Details
The purpose of this research is to realize a PM linear motor whose maximum acceleration is higher than 980m/s^2 (=100G) and whose maximum speed is higher than 20m/s. Up to date, we have made experimental linear motor which has low cogging force, the maximum acceleration higher than 545m/s^2 and the maximum speed higher than 10.5m/s. In this paper, we describe a design of a movable component and examine the driving performance of the linear motor. As a result, we designed the movable component with theoretical thrust density more than 980N/kg, and the experimental result shows that the maximum acceleration improved in 597m/s^2, and the greatest speed improved in 11.2m/s.
