Abstract

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.
