Linear permanent magnet (PM) brushless dc motor (LPMBDCM) is used for electromagnetic catapult, which may offer significant advantages, in terms of efficiency, high speed and accelerations of heavy payloads, capability of high forces, and so on. In this paper, an LPMBDCM, which is constructed of transverse flux stator and PM mover, is investigated. First, the launch specifications and technical features...
It is useful to adopt sub-power supply in linear motor for high efficiency. Zero-crossing detection technology is usually used in phase and frequency measurement. In this paper, zero-crossing detection technology is firstly applied to track transportation for sub-power supply. The performance of traditional zero-crossing detection technology in existence is compared particularly in this paper, and...
