Agribusiness, EarlyView.ABSTRACT Since the final decade of the 20th century, Latin American countries have increasingly regarded the signing of regional trade agreements (RTAs) as a promising strategy for expanding their exports. Within this context, the main objective of this study is to assess the impact of RTAs on agri‐food exports in Latin America over the period 1990 ...

2017 IEEE International Electric Machines and Drives Conference (IEMDC), 2017 This paper introduces a novel linear vernier permanent magnet machine (H-LVPMM) with high force density and low force ripple. The permanent magnets (PMs) on secondary uses Halbach array, which can provide a larger flux density in the air gap than that of the conventional surface-mounted PMs configurations, and the primary is composed of three modules ...

Research on Restraining Thrust Force Ripple for Permanent Magnet Linear Synchronous Motor
2006 CES/IEEE 5th International Power Electronics and Motion Control Conference, 2006Direct thrust force control will be applied to control permanent magnet linear synchronous motor. Thrust force ripple because of special end-effect of linear motor is bigger problem in the linear motor direct driving system without any conversion block.

Linear permanent magnet vernier machines (LPMVMs) have attracted more and more attention last several years due to its high thrust density at low speed, which is very suitable for the direct-drive applications. In this paper, the dual-side toroidal-winding LPMVM with unequal end-teeth width is proposed for the reduction of the detent force and thrust ...

This paper presents a method optimizing the thrust force of a Micro Electro Mechanical System (MEMS) Permanent Magnet Linear Motor, based on harmonic current injection. Fourier decomposition is implemented to the air gap flux density of the motor to derive the fitting expression of the thrust force dependent to exciting current.

Linear flux‐switching permanent magnet (LFSPM) machines have significant potential in many applications like urban rail transit, automobile and naval. In order to reach high thrust force capability, a sandwiched LFSPM machine (SLFSPM) is investigated in this paper to enhance the usage of both PMs and steel.
