ABSTRACT:
An improved power supply and drive system for an elevator is disclosed. An electric motor is connected to an electrical power source for a building. The electric motor is mechanically connected through a start-up clutch and an override clutch to a bevel gear assembly. A flywheel is also mechanically connected to the bevel gear assembly. The bevel gear assembly is connected through a disconnectig clutch to a conventional Ward Leonard elevator drive system, which includes a generator and a hoist motor. The electric motor is sized to generate a power output representing the integrated or average requirement of the elevator system over its prolonged duty, typically one-fourth of the size required in conventional systems. The bevel gear assembly, the flywheel, and the various clutches are provided to store energy used to operate the elevator during the relatively brief power surge requirements of the elevator system.
