In this gearless drive machine for lifts, a machine frame (1) arranged on a counter roller carrier (2) carries a bearing block (3) and an end plate block (4). An adjustable cable strand spacing can be made by means of the machine frame (1) and a counter roller (5) arranged at the counter roller carrier (2), whereby a left-hand and right-hand overhang of the counter roller (5) is possible with the same build-up of the machine frame. A main shaft (6) is borne at two places at the drive output side by means of a loose bearing, (7) arranged at the bearing block (3) and a fixed bearing (8) arranged at the end plate block (4). A drive pulley (9) with brake disc (10) is provided between the bearing places. The drive pulley (9) stands in firm connection with the main shaft (6) by means of a first tightening set (11). The bearing of the drive pulley (9) at both sides permits great radial loads for small deformations of the main shaft (6). A hoist motor (13) fed with alternating voltage consists substantially of a stator (14) with windings (15) and of a rotor (16) with a rotor hub (17) pushable onto the main shaft (6). A first tightening set (18) at the driven end of the main shaft (6) creates a firm connection between the main shaft (6) and the rotor hub (17).
