Optimal design of fine magnetic pole pitch fabricated on printed circuit board

Abstract

Using traditional methods, a permanent magnet multipole component magnetized with a magnetic pole pitch of less than 1 mm is very difficult to achieve and a costly, complicated magnetization system is required. In this paper, the optimal design of a fine magnetic pole pitch of less than 1 mm fabricated on a printed circuit board has been successfully investigated and demonstrated. An optimal magnetic pole pitch having large variation and strength in magnetic-flux density was obtained. The characteristics of the optimal magnetic pole pitch are good for signal detection and processing. The measured values of the magnetic-flux density in the z component are in agreement with the calculated values. (c) 2005 American Institute of Physics.
