Development of a magnetic linear motor based on a friction drive

摘要

A new type of magnetic linear actuator based on a friction drive is presented, It consists of a magnet mover with inclined legs and a solenoid coil wound around a pipe. rein alternating magnetic field produced by the coil causes the magnet to vibrate angularly due to magnetic torque and then the vibration is converted to a linear movement through a friction between the legs and the stator wan. The prototype exhibited the maximum velocity of 33 cm/s and the maximum thrust of approximately ly 0.05 N around the mechanical resonant frequency.
