Abstract: PURPOSE: A controller of an elevator is provided to decrease the high frequency vibration of an elevator by reducing a pulsation torque during the travel of an induction motor and to precisely calculate the combination of stator flux and load torque minimizing the power loss of the induction motor by equipping a magnetic flux order calculator. CONSTITUTION: A load detector(13) outputs an output proportional to a changed weight inside an elevator to a load torque converter. Firstly, the load torque converter receives an output value of the load detector to calculate unequal torque with a counterweight(17) and feeds the unequal torque to a torque current converter by subtracting and adding to a torque order calculated from a speed controller(2). Afterward, a flux order calculator(9) makes the magnetic flux of a stator of an induction motor strong when the speed order is lower for being strong to a low frequency disturbance occurring at a low speed for inhibiting the generation of low frequency vibration. Thus, a pulsation torque influencing badly riding comfort does not exist in the controlling device.
