More Information
Summary:A programmable permanent magnet actuator, a magnetic field generation apparatus and a method of controlling thereof. The actuator has a first body that is a ferromagnetic material, a second body that is a single magnetized ferromagnet and a magnetic field generation device associable to the second body to generate a magnetic field in proximity with the second body. The actuator also has a controller adapted to control the magnetic field generation device to generate a controlled magnetic field. The controlled magnetic field is adapted to modify a magnetization of the second body such as to produce with the second body a required magnetic field to move one of the first or the second body with respect to one another according to a desired position or a desired torque. The desired position or the desired torque is maintained even after the application of the controlled magnetic field. The apparatus has a permanent magnet that has an intrinsic coercivity (Hci) value that is greater than 200 kA/m and a remanence (Br) value that is greater than 0.4 Tesla. The apparatus also has a magnetic field generation device associated to the permanent magnet and a controller connected to the magnetic field generation device. The controller is adapted to control the magnetic field generation device to produce a controlled magnetic field to variably modify a magnetization of the permanent magnet in order to produce a desired variable magnetic field and influence the electrically charged or magnetized material when placed in the desired variable magnetic field.
