ELEVATOR DRIVE SYSTEM INCLUDING RESCUE OPERATION CIRCUIT |
摘要 |
A system continuously drives an elevator hoist motor during normal and power failure conditions. A regenerative drive delivers power from a main power supply to the hoist motor during normal operation. A rescue operation circuit includes a backup power supply and is operable in the event of a failure of the main power supply to disconnect the regenerative drive from the main power supply and connect the back up power supply to the regenerative drive to provide substantially uninterrupted power to the hoist motor. |
