[Claims for Utility Model Registration] (1) The AC motor connected to the inverter, which controls an inverter according to a difference signal between a speed signal indicating the rotational speed of the AC motor and a predetermined command signal. In an elevator control device that drives the AC motor with variable voltage and variable frequency AC power, and controls the regenerative power to be guided to the regenerative power consuming circuit during regenerative operation of the AC motor, the temperature of the elements of the regenerative power consuming circuit is controlled. When it is determined that the temperature sensor to be detected and the temperature signal of the temperature sensor are energized and the AC motor is in a regenerative operation state, the inverter is controlled so that the temperature signal is deenergized. An elevator control device comprising an inverter control circuit. (2) The elevator control device according to claim 1, wherein the regenerative power consumption circuit has a resistor as an element, and the temperature detector detects the temperature of the resistor. (3) The elevator control device according to claim 1, wherein the regenerative power consumption circuit has a transistor as an element, and the temperature detector detects the temperature of the transistor. (4) Request for registration of a utility model characterized in that the above-mentioned inverter control circuit includes a switching device that determines that it is in a regenerative operation state when a speed signal indicating the rotational speed of the AC motor becomes larger than a predetermined command signal. An elevator control device according to items 1 to 3 of the range.
