Apparatus for controlling an elevator

PURPOSE: An apparatus for controlling an elevator is provided to reduce the manufacturing cost of the elevator by controlling a synchronized motor through a converter. CONSTITUTION: A condenser(203) flattens the output voltage of a converter(202). An inverter(204) converts the DC voltage which is outputted from the condenser(203) to an AC voltage. A synchronized motor(205) generates a counter electromotive force. A current detector(206) detects the current which is supplied from the inverter(204) to the synchronized motor(205). A velocity and position detector(207) detects the position of a car(210). The apparatus comprises a brake(209), a detector(212), a controller(213), an inverter controlling section(214), and a gate driving section(215).
