Moving iron actuator

چکیده
– The paper describes design and optimisation of a tubular moving-iron linear permanent magnet motor for reciprocating compressor using finite element. The four leading design parameters are optimised individually. To validate the process reaches an optimal design, two leading parameters are varied simultaneously. This is due to one parameter may influence other parameters. The linear motor is aimed to produce 88.5 W output power which is enough to operate household refrigerator compressor system. . To reduce material and manufacture cost, Strontium Ferrite and soft magnetic composite are used in this design.

A Moving Magnet Actuator for Large Range Nanopositioning
In this paper, we present the design, fabrication, and testing of a moving magnet actuator (MMA) for large range (∼10mm) nanopositioning. MMAs are direct-drive, single-phase electromagnetic linear actuators that provide frictionless and backlashfree motion. These qualities, along with an adequate motion range, make MMAs promising candidates for large range nanopositioning. In this work, we iden...
متن کاملThe Application of NdFeB in the Magnetic Force Actuator
In this paper, NdFeB is used to design a new type of magnetic force actuator (MFA) with simple structure and high reliability. The permanent magnets are fixed on the static iron-core to generate a magnetic field, while the movable part locates within the magnetic field. It can drive the arc extinguishing unit powered by the Lorentz force, and this can be applied to the operation of the long-str...
متن کاملDevelopment of Film Actuator Operated by Magnetic Field for Micro-Machine
Fe-Pd alloy films, prepared by using a DC magnetron sputtering method, were developed as a high sensitive actuator, which was driven by the magnetic field. Fe-Pd alloy film shows large magnetostriction and high magnetostrictive susceptibility under 1 kOe. To evaluate the moving potential as magneto-driving actuator, the magnetostrictive properties were measured under different tensile loading s...
متن کاملDesign of Auto-focusing Modules in Cell Phone Cameras
Endowed with Hall-effect sensors and voice coil motors, cell phone cameras as intelligent systems are capable to execute auto-focusing for acquiring sharp image. For the use of cell phone cameras, this study presents an innovative auto-focusing module. When coils are powered, induced magnetic fields generate N and S poles around iron cores in the actuator. Unlike voice coil motors that employ L...
متن کاملExperimental Evaluation of Triple - Stage - Actuator System with Thermal Actuator for Hard Disk Drives *
Abstract To improve positioning accuracy in a head-positioning control system for hard disk drives, we have developed a triple-stage-actuator system on a spin-stand tester. In this system, the first stage is a VCM actuator for moving a head-stack assembly, the second stage is a PZT actuator for moving a suspension, and the third stage is a thermal actuator for moving read/write elements. The fr...
