Title: Dragster Project: emphasis on control
1Dragster Project emphasis on control
2Control
- The dragster project focuses on control
- Controlling electric motors is the basis for many
applications in industry Examples of applications
include standard power tools and machines
(most electric drills will reverse direction) - automated machines, CNC machines, and robotic
machines - Control of motors is primary desired motion is
secondary
3What is a dragster?
4Shirley Muldowney NY won the Top Fuel
Championship in 1977, 1980, and 1982 ranked 5th
in all time speed driver list. Muldowney is
Irish American Dont forget Tracey!
