摘要
Electro permanent magnetic clamping head comprising permanent magnets (2, 3) with different coercive field size field, and the magnetization coil (4) and an open magnetic circuit forming two magnetic poles (1, 5), in which at least one permanent magnet (2) the higher value of coercivity has a cylindrical shape and is placed in the cavity of at least a permanent magnet (3) the lower value coercivity, which has the shape of a hollow cylinder, the preferred arrangement is a permanent magnet (2) a higher value coercivity, permanent magnet (3) with the lower value of coercivity, magnetization coil (4), the central magnetic pole (1) and peripheral magnetic pole (5) axially symmetric. Electro permanent magnetic clamping system that includes a magnetic clamping electro permanent head according to this invention, a pulsed current source so that the serial RL, L, C circuit generating mode capacitor C discharge current pulse is designed to be a transitory phenomenon magnetizing current magnetizing coil L (4 ) has been working in the power level of aperiodicity.
