Abstract:
An elevator driving device comprises a sheave (8) on which a main cable (3) for suspending an elevator cage (2) is wound. A plurality of electric motors (13, 23) are provided for driving the sheave through speed reduction mechanisms (12) and control circuitry (27) is provided for allowing motors to operate simultaneously in a parallel mode or individually.
