Abstract
A door operator capable of manual operations includes an output unit, a drive unit, a transmission unit, a brake unit, and a manual chain unit. The drive unit is disposed between the transmission unit and the brake unit. The output unit is disposed on a first side of the drive unit, the transmission unit and the brake unit. The manual chain unit is disposed on a second side of the drive unit, the transmission unit, and the brake unit that is opposite to the first side. During a manual operation mode, the brake unit provides a brake force on the drive unit and the manual chain unit is configured to generate rotational inertia, and the rotational inertia is transferred to the output unit via the brake unit, the drive unit and the transmission unit.
