    摘要： A vibration control device for a rotating machine in which a primary yoke is provided within a hollow space of a secondary yoke so that the secondary yoke rotates about a shaft inserted through the primary yoke. A plurality of electromagnet portions are arranged around a peripheral surface of the primary yoke and there are a pair of sensors and a control portion. The electromagnet portions include at least a pair of first and second electromagnet portions and another pair of third and fourth electromagnet portions. The first and second electromagnet portions so arranged opposite to each other with respect to an X-axis direction, while the third and fourth electromagnet portions are arranged opposite to each other with respect to a Y-axis direction. One sensor detects a positional displacement between the primary and secondary yokes with respect to the X-axis direction, while another sensor detects a positional displacement between the primary and secondary yokes with respect to the Y-axis direction. A positional displacement detected by one sensor is controlled to be reduced by controlling electric current supplied to the first and second electromagnet portions, while a positional displacement detected by another sensor is controlled to be reduced by controlling electric current supplied to the third and fourth electromagnet portions. By electromagnetically controlling the positional displacement between the primary and secondary yokes with respect to each of the axial directions, vibration of the shaft is reduced.

    摘要： A suspension type hoisting apparatus has the position of an elevating portion, which is elevatably suspended from a base via a suspension member, adjusted by a positioning member for positioning the suspension member suspended from a carriage in the horizontal plane. The suspension type hoisting apparatus also includes a position controller for outputting a velocity reference signal on the basis of a deviation between a position reference signal of the positioning member and the actual position thereof, and a velocity controller for outputting a force reference signal being a manipulated variable of the positioning member on the basis of a deviation between the velocity reference signal, of the positioning member, outputted from the position controller and the actual velocity thereof; wherein a sway velocity of the elevating portion is detected. A sway controlling signal, with respect to the positioning member, is generated on the basis thereof, and the sway controlling signal is added to the force reference signal outputted from the velocity controller. Thereby, in a case where there is sway at the elevating portion, the positioning member is equivalently displaced in proportion to a sway velocity of the elevating portion, the sway of the elevating portion is suppressed in a remarkably short time, and at the same time, the elevating portion is accurately positioned at a reference position along with attenuation of sway of the elevating portion.
