Abstract
An electromagnetic precision rotary drive for a disk-shaped rotor. Along a peripheral annular zone of the rotor an armature band with a periodical pattern is disposed, which, within each period, varies continuously between the inner and the outer edge of the annular zone. The rotor is surrounded by a magent support, which carries at least one permanent magnet. If the magnet support is moved back and forth substantially radially, a torque is exerted on the rotor due to the interaction between the permanent magnet and the armature band.
