摘要:
An apparatus for controlling an AC powered elevator and for improving the safety of the operation of the elevator includes: a three-phase AC power source; a drive device connected to the three-phase AC power source for converting an AC signal into an AC power having a variable frequency, thereby enabling the controlling of an induction motor; a winding induction motor connected to and controlled by the drive device for driving the cage of the elevator; a door induction motor connected to and controlled by the drive device for opening or closing the cage door provided at the cage of the elevator; and a motor control command device having an operation command generator which generates a command for starting or stopping the cage of the elevator so as to control the drive device and a door command generator which generates a command for opening or closing the cage door so as to control the drive device for independently controlling the winding induction motor and the door induction motor.
