A door operator system for opening and closing an opening, comprising a door frame comprising a first frame section and a second frame section on either side the opening. The door is connected to the door frame. A drive unit mounted on the door is moveably connected to first frame section and the second frame section. The drive unit has at least one motor connected to at least one energy storage device arranged to power the at least one motor to move the door from the closed position to the open position. An energy transmitting device is disposed in close proximity to the door and an energy receiving device mounted on the door. The energy transmitting device wirelessly transmits energy to the energy receiving device mounted to the door. The energy receiving device is operatively connected to the at least one energy storage device for charging said energy storage device.

Door operator system with wireless charging capability

A sectional door operator system for opening and closing an opening comprises a door moved between open (O) and closed (C) positions and formed by horizontal and interconnected sections. The door is connected with a door frame with frame sections on opposite sides of the opening. A drive unit system is mounted on one of the sections that moves the sectional door from the closed position (C) to the open position (O). The drive unit system comprises first and second drive units, mounted on opposite sides of the section that each have a drive motor. A sensor device is mounted on a section and connected with a control unit. The control unit controls the drive unit system at least based on sensor data. The sensor data relates to an angle (φ) of the door in relation to a true horizontal plane of the sectional door operator system.

Sectional door operator system

A sectional door operator system (I) opens and closes an opening () by operating a plurality of horizontal and interconnected sections (-) that form a sectional door. A door frame () is formed by first frame section () at a first side () of the opening () and a second frame section () at a second side () of the opening (). The plurality of horizontal and interconnected sections (-) are connected to the door frame () to move between an open and a closed position. A drive unit (IO) is mounted on a section () of the door. The drive unit (IO) is arranged to move the sectional door () from the closed position (C) to the open position (). The drive unit (IO) includes a first motor (I la) and a second motor (I lb, which are mounted at different vertical sides of the horizontal and interconnected section (). A control unit () controls the operation of the drive unit (IO). A first sensing element () and a second sensing element () provide operational data of the first and second motor () to the control unit ().
