Magnetic pole position detection is the core of closed-loop control system permanent magnet linear synchronous motor (PMLSM), and its estimation accuracy directly affects performance dynamic response speed. In order to solve problem increased error magnetic caused by field distortion at end PMLSM while also considering cost hardware, paper uses four Hall sensors as components adopts an optimize...

In this paper, we have modeled and simulated the magnetic field of conductor by using finite element method, which is incorporated in Ansoft Maxwell software. Modeling simulation are done for a two conductors located at small distance between them. Our study based on method elements Biot-Savart law calculating depending from conductor. We observed that calculated values good accordance with [1]...

Flexible electronic printing technology is a scientific that uses an “ink” material with conductive, dielectric, or semiconductor properties printed on flexible web substrate to achieve precise preparation of devices, which are widely used in information, energy, medical, and military fields. In the process electron webs under complex working conditions, moving will experience substantial unsta...

Ansoft Corporation recently acquired Compact Software. This new development offers a win-win relationship among Ansoft, Compact, and — most important — the microwave/wireless circuit design industry. Ansoft wins advanced linear and nonlinear circuit simulation; Compact wins enabling electromagnetic (EM) simulation technology; and the microwave industry wins a clear, viable and comprehensive sol...

The chapter deals with the techniques used for the design, fabrication and measurement of antennas. The design and simulations are performed using the FEM based Ansoft High Frequency Structure Simulator (HFSS). The antennas are fabricated using photolithographic method.VNA HP8510C and Agilent PNA 8362B are used to measure antenna characteristics such as return loss, radiation pattern, gain etc....

Aiming at the impact of heat generation and temperature rise on driving performance a permanent magnet (PM) motor, taking PM in-wheel motor (IWM) for electric vehicles as an object, research is conducted into distribution electromagnetic–thermal effect cooling structure optimization. Firstly, coupling model considering electromagnetic harmonics established using subdomain Bertotti’s iron loss s...
