Abstract
A drive unit for a door includes an electronically commutated multipole motor having: a stator part configured to be arrangable at a stationary structural component part; and a rotor part configured to be gearlessly connectable to a rotationally drivable element. The stator part and the rotor part include sheet metal elements stacked in a package-like manner. The sheet metal elements of the stator part and the sheet metal elements of the rotor part extend parallel to one another.
