Linear drive for sliding doors or the like
Abstract:
A linear drive based on linear motors, for panels, in particular sliding doors, movable along a respective travel path. A linear drive for at least one panel, in particular a sliding door leaf, movable along a travel path, has at least one linear motor for this at least one panel. The linear motor is provided with a stator member and a carriage. Furthermore, the linear drive has a control circuit. The control circuit is adapted to stop the linear motor in the event of failure of power supply to the linear motor, by switching-off the linear motor and operating it as a generator. Thereupon, in terms of its displaceability, this movable panel is enabled by the control circuit. In addition, the linear drive has a switch for switching-off the energy supply to the at least one linear motor.
