Coil i.e. drive coil, for magnetizing permanent magnet, has slots and/or recesses provided in single-piece coil body, and conductor sections forming single piece conductor, where cross-sections of conductor sections are square-shaped

摘要

The coil (11) has a single-piece coil body (12) and a coil base body, where the coil is formed right-angled and made of an electrically conductive material e.g. silver, aluminum, copper, or alloy of silver, aluminum, or copper. Slots and/or recesses are provided in the coil body. Conductor sections form a single piece conductor, where the cross-sections of the conductor sections are square-shaped. The single-piece coil body has regions with different pole adjustment.
