The invention relates to an a drive machinery for an elevator, the drive machinery comprising a rotatable drive sheave for driving plurality of ropes of the elevator, the drive sheave comprising a central cylinder, which comprises a central axis around which the central cylinder is rotatable; plurality of circular rim members surrounding the central cylinder, each said rim member comprising an outer rim surface for engaging a rope. Said plurality of circular rim members includes one or more rotatably mounted circular rim members, each said rotatably mounted circular rim member being mounted on the central cylinder rotatably around said central axis relative to the central cylinder and relative to one or more of the other circular rim members, and in that said drive sheave moreover comprises a control means for controlling rotation of each said rotatably mounted circular rim member relative to the central cylinder and relative to one or more of the other circular rim members. The invention also relates to an elevator implementing the drive machinery.

A driving system for an elevator. The driving system includes a motor, a power source, a battery device, a conversion circuit, a power path circuit and a controller. The motor controls a movement of the elevator in response to a driving power. The power source provides a source power. The battery device stores a battery power. When the elevator is moving, the controller controls the power path circuit to generate a power delivering path between the conversion circuit and the motor, and controls the conversion circuit to convert the battery power into the driving power. When the elevator is at rest, the controller controls the power path circuit to generate a charging path between the conversion circuit and the power source, and controls the conversion circuit to convert the source power into the battery power.
