Abstract

The invention relates to an electrostrictive or magnetostrictive motor or a generator which can generate linear movement. The magnetostrictor actuator comprises a rigid non-magnetic support and a magnetostrictor which is arranged in the rigid non-magnetic support; one side of the rigid non-magnetic support is provided with a through opening, or two opposite sides of the rigid non-magnetic supportare provided with through openings; a rigid magnetic rod which can freely move relative to the through opening is arranged in the through opening and is fixedly connected with the magnetostrictor; a rigid magnetic support is arranged outside the rigid non-magnetic support; one lateral side of the rigid magnetic support is open, and the other lateral sides are closed; an electromagnetic coil is winded round the periphery of the rigid magnetic support; the magnetostrictor, the rigid magnetic rod and the rigid magnetic support form an electric magnetic flux circuit; the rigid magnetic rod can freely move relative to the open side of the rigid magnetic support; and the rigid non-magnetic support and the rigid magnetic support are fixedly arranged. The mechanism of the invention can be used for researching and producing the instrument and the equipment requiring large-displacement, large-load and high-precision driving function.

Description

technical field [0001] The present invention relates to a motor or generator utilizing electrostriction or magnetostriction for producing linear motion, and more particularly to an actuator. Background technique [0002] In recent years, the field of electric and magnetostrictive materials has developed rapidly, and new magnetostrictive smart materials such as giant magnetostrictive materials and magnetostrictive shape memory alloys have been produced, which can be used in the development of precision actuators. These materials have It has the advantages of high energy density, high output power, large expansion and contraction deformation, and precise control. However, the actuation devices developed based on such stretchable materials often require high current excitation that can generate strong electromagnetic fields in order to achieve large telescopic displacement and large load actuation capabilities. However, due to the limitation of the design structure of the brak...
