The finite element analysis of the linear hybrid reluctance motor for the electromagnetic launch system

The Electromagnetic Aircraft Launch System (EMALS) is being developed utilizing electrical and electronic technologies. EMALS is emerging in order to replace the existing steam catapult on naval carriers. Recently, the double-sided linear launcher has drawn increasing attention of researchers. This paper presents the design and analysis of the Linear Hybrid Reluctance Motor (LHRM). This new mot...

Comparison between Radial and Halbach Array PMLSM by Employing 2-D Electromagnetic Finite Element Analysis

The replacement of steam catapults with electromagnetic ones is becoming an overwhelming trend in aircraft launch systems. The Electromagnetic Aircraft Launch System (EMALS) offers significant benefits to the aircraft, ship, personnel, and operational capabilities. EMALS has such advantages as high thrust, good controllability, reusable, etc., as a launching motor, a double-side plate Permanent...

Finite element analysis of a fast electromagnetic actuator

The present paper is devoted to the modelling of a fast c ing linear electromagnetic a tuator in which t e mechanical and electrical time constants are of the same order of magnitude. The computation of the electromagnetic and the mechanical quantities must then be performed simultaneously. This paper describes the algorithm used to solve 00th the Maxwell's equations and the equation of motion.

A Parallel AMG Solver for An Electromagnetic Finite Element Analysis

The algebraic multigrid (AMG) method is not only efficient in solving for linear systems arising in finite element analyses, but also applicable at a matrix level without geometric information on the domain, different from the geometric multigrid solvers. The present paper proposes a combination of the parallel processing technique and the AMG method as a fast solver for electromagnetic field a...
