Magnetic actuator under piezoelectric control

摘要

A magnetic actuator for adjusting a force on a load is presented herein. The magnetic actuator comprises a first actuating part that includes a first magnetic element and a second magnetic element, a second actuating part that includes a third magnetic element and a piezoelectric element attached to the first and second magnetic elements to relatively displace the first and second magnetic elements. The first actuating part and said second actuating part are constructed and arranged to generate a magnetic force between both actuating parts along a first direction with a load being attached to one of the first and second actuating parts.
