ABSTRACT:
An electric linear drive comprises a housing in which an external rotor electric motor is mounted. The motor has its stator fixedly mounted on said housing while on the other hand the rotor of the motor has a male screw thread thereon on which a bush is screwed. The bush is joined to a thrust rod and there are means for guiding the bush axially in the housing so that it may be moved into and out of the housing with a telescoping effect. This guiding means is furthermore designed for limiting the axial stroke of the thrust rod.
