Design Methodology of a Dual-Halbach Array Linear Actuator with Thermal-Electromagnetic Coupling
This paper proposes a design methodology for linear actuators, considering thermal and electromagnetic coupling with geometrical and temperature constraints, that maximizes force density and minimizes force ripple. The method allows defining an actuator for given specifications in a step-by-step way so that requirements are met and the temperature within the device is maintained under or equal ...
متن کاملMagnetic Field of Tubular Linear Machines with Dual Halbach Array
Permanent magnet (PM) array affects flux field distribution of electromagnetic linear machines significantly. A novel dual Halbach array is proposed in this paper to enhance flux density in air gap, and thus to improve output performance of linear machines. Magnetic field in three-dimensional (3D) space of a tubular linear machine with dual Halbach array is formulated based on Laplace’s and Poi...

متن کاملElectromagnetic Vibration Energy Harvesting Using an Improved Halbach Array
This paper reports an electromagnetic vibration energy harvester using an improved Halbach array. A Halbach array is a specific arrangement of permanent magnets that concentrates the magnetic field on one side of the array while cancelling the field on the other side to almost zero. Previous research showed that although the Halbach array has higher magnetic field density compared to normal mag...
متن کاملA Planar Electromagnetic Vibration Energy Harvester with a Halbach Array
This paper presents a low-profile, planar electromagnetic vibration energy harvester integrated with a Halbach array. Halbach array is a special arrangement of permanent magnets that doubles the magnetic field on one side of the array while cancelling the field to near zero on the other side. Using this arrangement can improve electromagnetic coupling in a limited space. The energy harvester ha...
