Linear or Rotary Actuator Using Electromagnetic Driven Hammer as Prime Mover [PDF]
We claim a hammer driven actuator that uses the fast-motion, low-force characteristics of an electro-magnetic or similar prime mover to develop kinetic energy that can be transformed via a friction interface to produce a higher-force, lower-speed linear ...
