Abstract :
Tubular linear permanent magnet machine with gas springs using for drilling applications is presented. This machine has the advantage of directly transmitting electric power to rock without gears. In this paper, mathematical model with hammering effect is established and dynamic process of oscillatory motion is analyzed. Simulation results show that this machine is suitable for drilling application.
