A drive unit for a revolving door (100) having a turnstile (13), the drive unit comprising:

• an electronically commutated multipole motor (1) having:
• (i) a disk-shaped or cup-shaped stator part (10) configured to be arrangable at a stationary structural component part (11) of the revolving door (100),
• (ii) a disk-shaped or cup-shaped rotor part (12) configured to be gearlessly connectable to the turnstile (13) of the revolving door (100), and
• (iii) an engagement device (14) arranged between the stator part (10) and the rotor part (12), the engagement device (14) being configured to intervene in rotational movement of the rotor part (12),
• wherein the stator part (10) and the rotor part (12) are in a plane-parallel arrangement with respect to one another.
