Electric motor rotary drive e.g. for computer tomography, has sector-shaped stator with ends facing rotor with increasing distance from rotor starting from curved inside of stator parallel to outside of rotor

摘要

The device has at least one stator (4) extending over a sector of its circumference and a rotor with a permanent magnet. End zones (6) on the peripheral ends (18) of the stator have ends (7) facing the rotor (2) with an increasing distance from the rotor starting from the curved inside of the stator parallel to the outside (8) of the rotor.
