Beyma T25M Pole Piece & Cap

Beyma T25M Pole Piece

  • The magnet system has been optimized with the latest FEA software to squeeze the ceramic magnet to the limit.

  • T-shaped pole piece covered with a copper cap gives extremely symmetric force factor figures

  • The copper reduces harmonic distortion figures to the minimum and keeps the inductance down

  • Vented pole piece, flared on the top helps to get the steel saturated, while avoiding resonances together with damping material

  • Back radiation gets absorbed with three different carefully-selected damping materials behind the dome
