Abstract (en)
This invention relates to a door mechanism (1) comprising: a drive element (2) which is connected to a door (5) for moving the door. A primary motor (8) rotates the primary pulley (3) and moves the drive element (2). Also a secondary motor (9) rotates a secondary pulley (4) and moves the drive element (2). To obtain a cost efficient and energy efficient door mechanism, the controller (10) controls supply of electricity to the primary motor (8) and the secondary motor (9) independently of each other such that mainly electricity is supplied to the primary motor only, and such that electricity is supplied simultaneously to both to the primary motor (8) and secondary motor (9) only in predetermined situations.
