This drive for an escalator is installed on one or both sides of the escalat or at the lower and/or upper end and comprises one to several identically constructed drive units (7), which are arranged distributed at the circumference of a main drive wheel (6 ). The drive units (7) can be flange-mounted in longitudinal or transverse direction to t he direction of travel of the escalator on a common main gear housing (8) always identical f or one to n drive units (7). Connecting openings (24) not needed at the main gear housin g (8) are closed by a cover. The motors of the drive units (7) are controlled by way o f a common frequency-setting device. A control and regulating unit processes input data of different components and functional groups into control and regulating data for the frequency- setting device, the relay control and the optical signals and illumination. The individual drive units (7) are switched in or out according to the actual power requirement.
