Optimal design of FRLSM to increase thrust and reduce the detent force
Digests of the 2010 14th Biennial IEEE Conference on Electromagnetic Field Computation, 2010This study presents an optimal configuration of Flux-Reversal Linear Synchronous Motor (FRLSM) with the optimal number of attachment permanent magnets (PMs). The optimal model of 2000 (N) is designed to reduce detent force by redesigning the air-gap structure and skewing.

Ending Forced Labor In ICE Detention Centers: A New Approach
SSRN Electronic Journal, 2020Privately managed detention centers hold the majority of immigrant detainees in Immigration and Customs Enforcement custody. Coerced detainee labor in these for-profit facilities is commonplace. The practice contributes significantly to the financial viability of CoreCivic and GEO Group, the two corporations that manage ICE detention centers, but it ...

Analysis and Reduction of Detent Force on a Novel Transverse Flux Permanent Magnet Linear Machine
IEEE Transportation Electrification Conference and Expo, Asia-PacificDue to the influence of end effect, the air-gap magnetic density at both ends is seriously distorted, which results in high detent force. In this paper, a typical transverse flux permanent magnet linear machine (TFLM) is introduced to analyze the detent ...
