The invention relates to a drive device (1) having an annular stator unit (10), an annular rotor unit (30) and a base plate (50). The stator unit (10) has at least three coils (11) having coil cores (12) and coil bobbins (13). The rotor unit (30) has a bearing unit (31), the coils (11) forming a receiving space (14) in the stator unit (10). According to the invention, the coil cores (12) and the bearing unit (31) stand on the base plate (50). The invention also relates to a spin window (100) having such a drive device (1), a pane (110) being arranged on the rotor unit (30).
