    摘要： A control device sets parameters “n”, “ad”, “pd”, “aq”, “pq” and the like of a motor parameter setting unit, corrects a d-axis current command value outputted from a d-axis current instructing unit and a q-axis current command value outputted from q-axis current instructing unit based on these parameters of the motor parameter setting unit, on a detection result of a rotation angle detection unit, and makes a (6×n)f sine component, (6×n)f cosine component, (6×(n+1))f sine component, and (6×(n+1))f cosine component of torque to zero. In such a way, 6×n and 6×(n+1) ripple components and the like, which are generated in a motor provided in elevator equipment or the like, are suppressed, and a torque ripple of the motor is reduced to a large extent.

    摘要： A magnet unit includes a first magnetic pole (7a), a second magnetic pole (7b) and a third magnetic pole (7c) at a center between the first magnetic pole (7a) and the second magnetic pole (7b), providing an E-shaped configuration. In the magnet unit, a first magnet is defined between the first magnetic pole (7a) and the third magnetic pole (7c) by connecting two electromagnets (71aa, 73aa) with each other through a permanent magnet (72a), while a second magnet is defined between the second magnetic pole (7b) and the third magnetic pole (7c) by connecting two electromagnets (71ba, 73ba) with each other through a permanent magnet (72b). With this configuration, it is possible to reduce a deviation in the length of respective magnetic paths from the permanent magnets (72a, 72b) up to their respective magnetic poles. By controlling exciting currents to the respective magnetic poles. By controlling exciting currents to the respective electromagnets (71aa, 73aa, 71ba, 73ba), it is also possible to adjust fluxes (or flux density) in respective directions x, y individually.

    摘要： A strip thickness controller for a rolling mill, which is capable of reducing a delivery-side strip thickness deviation due to an eccentricity of a backup roll even in a rolling mill incapable of easily performing a kiss-roll. The strip thickness controller provides with a thickness gauge, provided in a position spaced a distance shorter than a circumference of each of backup rolls on a delivery side of the mill, for detecting a strip thickness deviation from a set value, an angle detecting unit for outputting a rotational angle detection signal at every equally-segmented portion when an angle of one rotation of the backup roll is, with “n” being a positive integer, segmented equally by “n”, a calculating unit for calculating a forward slip of the mill at a point of time when a first rotational angle detection signals outputted, and calculating, based on the forward slip and the circumference of the backup roll, a delivery-side strip length of the rolling mill which corresponds to one rotation of the backup roll and a delaying unit for delaying a strip thickness deviation signal of the thickness gauge by a strip transfer time corresponding to a difference between the delivery-side strip length calculated by the calculating unit and a distance of the thickness gauge from the rolling mill.
