Abstract
An elevator control apparatus reducable in size by securing an installation space with ease, and which is excellent in noise immunity. A winch operates a car to perform an upward and downward movement, a motor generates a driving force for the winch, an inverter controls the motor to change its rotational speed in a variable manner, and an ECU controls the inverter. The winch, motor, inverter and ECU are integrally constructed with one another and installed as a drive control device. In addition, a traffic control device controls the traffic operation of the car by generating a traffic pattern corresponding to a destination floor from a current position of the car in response to a hall call or a car call. The traffic control device is separate from the drive control device.
