摘要： A permanent magnet electric machine such as, for example, a motor or generator, including a permanent magnet field member, an armature having salient magnetic poles and armature windings. A greatest common division of the number of magnetic poles of the field member and the salient magnetic poles having the armature windings differs from the number of magnetic poles. A group of grooves is formed between the salient magnetic poles having an interval of 2/3M.pi., with M being an integer which is not a multiple of three. To reduce the occurrence of cogging torque, auxiliary grooves are provided on the surface of the salient poles at positions which are spaced apart from positions of the grooves by (.pi./3)K+(.pi./6), in terms of electrical angle, with K being an integer.

摘要： An insert member (42) having an identical permeability is fitted in the circular center hole(41a) of a magnetic ring (41) which is then fitted in the circular hollow section (43a) of a fitting-over member (43) having an identical permeability. Under that state, the magnetic ring (41) is placed in a parallel magnetic field. Lines of magnetic flux passing through the magnetic ring (41) held between the insert member (42) and the fitting-over member (43) become linear without substantially inclining against the parallel magnetic field. Under that state, harmonic noise causing a deterioration in detection precision will scarcely appear in the output of a magnetic sensor for detecting the rotating magnetic field of a ring magnet (40) obtained by performing two-pole magnetization on the magnetic ring (41). When the ring magnet (40) is employed, a deterioration in the detection precision of a magnetic encoder (1) due to the magnetization state of the ring magnet (40) can be avoided, and the deterioration in detection precision can be suppressed.

摘要： The drive controller of an actuator previously measures positioning error of an actuator output shaft caused by the angle transmission error of a wave gear drive and stores it as correction data. In a feedback control loop, a speed feedback value ωf is computed using the detected position feedback value θf, after corrected by the correction data, of the actuator output shaft, and a current command Ir is computed using it, thus performing drive control on a motor. Since a speed component caused by the angle transmission error of the wave gear drive has been added to the rotational speed of a motor with regard to the speed feedback value ωf, a variation in rotational speed of the actuator output shaft caused by the angle transmission error of a wave gear drive can be suppressed effectively.

摘要： In a vacuum cleaner, both static pressure H.sub.data and a variation width .DELTA.H in the static pressure appearing when a suction port is operated are detected from a pressure sensor provided at a rear side of a filter within a main body of the vacuum cleaner; a current variation width .DELTA.pbi appearing when the suction port is operated is detected from a current of a nozzel motor for driving a rotary brush stored in a power brush suction port; an air quantity at the suction port is calculated from the current, rotational speed of a fan motor and static pressure; command values are newly obtained by performing a fuzzy calculation with the variation width .DELTA.pbi, static-pressure command value Hcmd; the variation width .DELTA.H and the static-pressure command value Qcmd; the variation width .DELTA.pbi and static-pressure command value Hcmd; and also the variation width .DELTA.H and static-pressure command value Qcmd as the input thereto; the rotational speeds of the fan motor and nozzel motor are controlled from the result of the command values; and further optimum air suction force is automatically obtained, depending upon the suction port under use and cleaning floor plane.

摘要： Sine wave signals generated from a position detector are used as analog values to detect a fine position of a rotating or moving body, a rise or fall edge of the sine wave signal is used to detect a coarse position of the rotating or moving body, and the position or speed of the rotating or moving body is detected based on a signal indicative of the detected coarse position when the rotating or moving body is at high speed and based on a signal indicative of the detected fine position when the rotating or moving body is at low speed to thereby provide optimal control from high speed to low speed. Especially at extremely low driving, speed detection with superhigh resolution is effected using the analog value to decrease an uneven rotation of the rotating body.
