Abstract: The research and application of the punching machine driven by a
linear induction motor (LIM) are introduced. The fundamental
principle, construction, performance and application are
described. Comparing this new model machine with its traditional
form, the LIM driven punching machine has many great
advantages, such as ,simple construction, small size and mass, ow
production cost, short production time, easy to control, low noise
and considerable energy saving.
Key words: Punching
