    摘要: A motor controller comprises a stator current production unit for producing stator current commands that are command values for the stator current flowing through the stator windings, a drive unit for supplying electric power to the stator windings based on the stator current commands, a stator current detection unit ZU, ZV, and ZW, for detecting the stator currents flowing through the stator windings, and a saturation degree production unit for producing a saturation degree indicating by how much the stator current is not following the stator current command. The stator current production unit produces the stator current commands based on the saturation degree. The saturation degree production unit produces the saturation degree based on the current commands, the stator current signals, and the pole-position signals.

    摘要: A phase-shift detection circuit detects a phase shift in motor driving, using pulse-shaped position detection signal Rd and measurement signal Ms. The position detection signal is based on sensor signal Hs from a position sensor disposed in a motor. The measurement signal is based on the induced voltage from windings. The phase-shift detection circuit includes a level difference calculator and a phase-shift calculator. The level difference calculator calculates a level difference between the level of measurement signal Ms at a rising timing of position detection signal Rd and the level of measurement signal Ms at a falling timing thereof. The phase-shift calculator calculates the amount of phase shifts based on the level difference.

    摘要: A centrifugal multi-blade impeller (10) that has a plurality of blades (11) around a central axis of rotation (10a) and that radially outwardly blows air taken in along the central axis of rotation is housed in a spiral scroll casing (20). The ratio of H/D of height H of the centrifugal multi-blade impeller in a direction of the central axis of rotation to diameter D of the centrifugal multi-blade impeller is 0.2 or less. The scroll casing has a logarithmic spiral spread angle γ of 2.0 degrees or more. It is thereby possible to provide a small and low profile centrifugal air blower that has high air blowing performance and is low noise.
