<P>PROBLEM TO BE SOLVED: To easily and accurately control terminal voltage and current of a motor to regulated values without requiring the complicated adjusting work by a worker. <P>SOLUTION: The motor control device for elevator, which controls drive of a motor 3 with a vector control method, comprises an automatic control constant adjusting section 18 for automatically adjusting a vector control constant so that the terminal voltage and current in the rated load operation respectively becomes a regulated value by using a predetermined calculation formula based on measured values of the terminal voltage, current and rotating speed of the motor 3 to be obtained in at least two different operating condition. <P>COPYRIGHT: (C)2009,JPO&INPIT |
