A resonant impact electric linear impact apparatus, comprising a cylindrical core (20), a columnar core (23), coils (8, 9), a shaft (12), a housing (1), and a resonant impact current coil (54). Both the cylindrical core and the columnar core are a multi-segment annular pole, and the coils have a simple annular shape, consuming fewer materials. One of the cylindrical core and the columnar core is a magnetizer core provided with a resonant impact current coil, and the other is a permanent magnet core or a magnetizer core provided with a direct current coil; the magnetizer core is formed by fixing a silicon steel sheet stacking assembly (37) by means of aluminum casting, allowing a simple and compact structure. The power of the resonant impact current coil is supplied by a resonant impact commutation current circuit (18) which is controlled by movable member position sensors (16, 17) to output a commutation current or a discontinuous current. The direction of the current or on/off of the current ...
