Coil spacing

A power tool comprising:

• a percussive mechanism with a percussive element to generate a percussive pulse onto a tool, the percussive element being reversibly movable along a longitudinal axis by a magnetic field in order to generate the percussive pulse;
• and
• at least a first and a second coil device to generate the magnetic field, each of the first and second coil devices having at least a first coil ring with a first radius and a second coil ring with a second radius, whereby the first radius of the first coil ring is greater than the second radius of the second coil ring, so that a space is formed, at least in certain areas, between the at least first and second coil rings, a fluid serving to cool the first and second coil devices flowable through the space;
• wherein the first and second coil rings are arranged with respect to each other in such a way that the distance between an upper end of an uppermost coil ring and a lower end of a lowermost coil ring of the first and second coil rings is greater than a sum of a first height of the uppermost coil ring and of a second height of the lowermost coil ring.
