Abstract
A linear drive for sliding doors, particularly linear drives based on linear motors. A linear drive, for at least one part which is movable along a movement path, particularly a sliding door leaf, has at least one linear motor for the at least one part. A stator part of the linear motor is received in a receiving profile so as to be prevented from falling out. The receiving profile is constructed to be arranged at a fastening device, which is arranged in turn on the installation side of a wall portion or top portion. Accordingly, the stator part and receiving profile form a module or unit, which can be mounted in its entirety. Therefore, a person performing the mounting can use the receiving profile for mounting, which helps to reduce the risk of damaging the stator part.
Claims16
A linear drive for a part movable along a movement path, comprising:
- a linear motor having a stator;
- a receiving profile that fixedly retains the stator;
- and
- a fastening device to which the receiving profile is mounted, an installation side of the fastening device is further adapted to be mounted on a wall portion,
- wherein the receiving profile comprises projections dividing an interior space of the receiving profile into two receiving spaces,
- wherein the stator is received in one of the two receiving spaces and
- wherein a rotor part of the linear motor is received and guided in the other of the two receiving spaces,
- wherein the receiving profile has a slide-on portion on at least one lateral side thereof.
