Abstract

In electromagnetically operated print hammers, the soft iron core of a pulse-energized coil is activated, forming a magnetic field in the operating air gap. The kinetic energy of the moved print hammer increases until coil energization is discontinued, so that the magnetic field collapses instantly.
