Abstract: A coil assembly has at least two coils which are arranged in a common plane, and partially overlap in crossover sections of the coils. The crossover sections have a reduced height, which results in a reduced total height of the coil assembly. This leads to a more compact coil assembly, and hence to better dynamic characteristics of a positioning device in which the coil assembly is applied.
