Abstract
A system may include a magnetic shape memory (MSM) element having a longitudinal axis that extends from a first end of the MSM element to a second end of the MSM element. The system may further include a rotatable permanent magnet configured to rotate around an axis of rotation and positioned proximate to the MSM element. The system may also include a first solenoid having a first solenoid axis directed at the rotatable permanent magnet. The system may include a second solenoid having a second solenoid axis directed at the rotatable permanent magnet. A method may include applying a first alternating current (AC) signal to the first solenoid and a second AC signal to the second solenoid to cause the rotatable permanent magnet to rotate.
Claims20
A system comprising:
- a magnetic shape memory (MSM) element having a longitudinal axis that extends from a first end of the MSM element to a second end of the MSM element;
- a rotatable permanent magnet configured to rotate around an axis of rotation and positioned proximate to the MSM element;
- a first solenoid having a first solenoid axis directed at the rotatable permanent magnet;
- and
- a second solenoid having a second solenoid axis directed at the rotatable permanent magnet.
A method comprising:
- applying a first alternating current (AC) signal to a first solenoid;
- applying a second AC signal to a second solenoid, wherein a first phase of the first AC signal is offset from a second phase of the second AC signal;
- in response to magnetic fields produced by the first solenoid and the second solenoid, rotating a rotatable permanent magnet;
- and
- in response to a rotating magnetic field produced by the rotatable permanent magnet, moving a contracted portion of an MSM element from a first end of the MSM element to a second end of the MSM element.
