On possibility of using periodic permanent magnetic structure to be initial energy source for a magneto-cumulative generator

Abstract

Summary form only given, as follows. In a lot of single-shot applications and experiments at remote locations where magneto-cumulative generator provides the most practicable power, it is impracticable to use a capacitor bank to be the initial energy source. Gdovnina et al. (1996) has used a permanent magnets to be the initial energy source to drive a magneto-cumulative generator, but the energy density stored in a single permanent magnet is very low. In this paper the possibility of using periodic permanent magnetic structure to be initial energy source of magneto-cumulative generator is analyzed numerically. It is concluded that 1 kJ initial energy can be provided to magnetocumulative generator by the periodic-ring permanent magnetic structure which weighs less than 30 kg and the outside radius less than 30 cm, and some relative technical problems are also considered.
