Claim:
1. A drive device, comprising: a first housing part having a connector configured to connect to one of a stationary base part and a movable component, a second housing part arranged substantially coaxial with the first housing part, configured to connect to the respective other of the stationary base part and the movable component, and directly or indirectly displaceably guided on the first housing part in an axial direction relative thereto, and a drive unit received in the first housing part and comprising a motor assembly for bringing about a relative displacement movement of the first housing part and the second housing part, the motor assembly comprising a rotor having a rotor shaft, two mounting elements for mounting the two ends of the rotor shaft, and two permanent magnet shells held on the mounting elements, wherein the motor assembly is received directly in the first housing part, and the first housing part is made of a magnetisable material at least in a length portion associated with the motor assembly, wherein at least one of the mounting elements comprises a holding recess holding at least one of the permanent magnet shells, and a wedge face cooperating with an associated counter wedge face on an axial longitudinal end of the at least one permanent magnet shell to hold the at least one permanent magnet shell in a defined radial position on the mounting element, and wherein the wedge face is inclined such that a radially outer edge of the wedge face is closer to the other respective mounting element than a radially inner edge of the wedge face extends increasingly radially outwards in a direction pointing towards a respective other axial longitudinal end of the at least one permanent magnet shell.
