Permanent-magnet manipulating mechanism

A permanent-magnet manipulating mechanism is composed of a static iron core with closing and opening coils arranged in the static iron core and near its two ends, a permanent magnet between the two coils, a moving iron core with an output rod connected at its end passing through the two coils and the permanent magnet, and an electronic control circuit. Its advantages are simple structure, high reliability and long service life (100,000 operations).
