The elevator drive system (1) has a drive motor (4) with a shaft (15) with a ball bearing (13) at one end. A rotating part (16) of a signal generator (17) is connected to the inner race (14) of the bearing. It rotates inside a fixed part (18) with a reading head. The motor shaft is directly connected to a drive shaft (7) with a central ball bearing (25) and a brake (5) at the end remote from the motor. Drive regions (3) have patterns of circumferential grooves (2) to accommodate cables (6) for the elevator cage and counterweight.
