摘要： PROBLEM TO BE SOLVED: To enable the transfer of fluid with strong driving force by reciprocating a mover in axial direction, in the section of shifting a soft magnetic substance column by making a magnetic pole attract it by the current application to an exciting coil. SOLUTION: Applying currents to an exciting coil 5b after shifting a mover 1 left only within the magnetic pole of a magnetic core 4b by the current application to an excitation coil 5a will make the magnetic pole at the right of the magnetic core 4c attract a soft iron column 1b and shift it right only within the magnetic pole, and load 3 also moves, corresponding to it. Hereby, the load 3 can be driven only within the magnetic pole right and left by applying currents to the exciting coils 5a and 5b alternately, and the driving force can be improved more greatly than the driving force by an electromagnetic plunger. As a result, fluid can be transferred by the large fluid pressure corresponding to the drive.

摘要： PURPOSE: To obtain a commutator device which increases the useful time of a motor by a method wherein, when a first brush is worn away so as to be lowered, a lever is fitted into the recessed part of the first brush so as to be moved. CONSTITUTION: Cylindrical brushes 8a, 8b are inserted into the inside of metal cylinders 7a, 7b so as to be slid and moved up and down, springs 9a, 9b are insatlled at their upper parts, and the brushes 8a, 8b are sprung downward. When the lower end of the brush 8a comes into sliding contact with a commutator so as to be worn away, the brush is lowered to the lower part, a lever 10a comes into contact with a recessed part 9, it is moved to the left part so as to be fitted, and the lever 10a escapes from the lower end of the brush 8b. Consequently, the brush 8b is sprung downward so as to be lowered, it comes into sliding contact with the commutator, and the supply of electricity from the positive terminal of a power supply is maintained. In this manner, when one brush is worn away, it is replaced automatically with a next brush, and the useful time of a brush is doubled. Since the respective brushes are housed in one enclosure, a mounting and removal process onto and from an electrically-driven body is simplified. In addition, a cmmutator device can be manufactured at low costs.

摘要： PURPOSE: To obtain a cylindrical reluctance linear motor in which an operator and a long rod can be moved to the left and right by detecting the position of a salient pole of the operator and controlling the conduction of a fixed armature coil thereby sustaining a high output. CONSTITUTION: An operator 4 is bonded to the central shaft of a column 1 and slides in the directions A and B. The column 1 is provided, on the outer circumference thereof, with annular protrusions 1a, 1b. Coils 10a-10c are secured to a fixed armature being spaced apart by 2/3 of the width of salient pole and mounted oppositely to the side face of salient poles 1a, 1b in order to obtain a position detection signal. If a high level position detection signal is inputted when the input to the underside of an AND circuit 41a has high level, transistors 20a, 20b are conducted thus conducting an armature coil 39a. When the conduction is interrupted by the end of the position detection signal, magnetic energy stored in the armature coil 39a does not return back to the DC power supply side because of a reverse flow preventive diode 49a-1 but charges a capacitor 47a through diodes 21b, 21a. Consequently, the current decreases abruptly.

摘要： PURPOSE:To obtain a control circuit by which a high-speed rotation can be performed by a method wherein, when an armature coil ia de-energized, its magnetic energy is stored in a capacitor, the high voltage of the capacitor is utilized and an armature coil to be next energized rises quickly. CONSTITUTION:When energization is stopped, magnetic energy in an armature coil 39a is carried to a capacitor 47a via diodes 21b, 21a since it is prevented from returning to DC power supply by a reverse blocking diode 49a-1, and thus a high voltage is generated. Consequently, since the magnetic energy is extinguished quickly and a current is dropped quickly, it is possible to prevent an countertorque from being generated. When transistors 20a, 20b are set conductive and the armature coil 39a is energized, an applied voltage becomes the sum of a charging voltage for the capacitor 47a and of a power supply voltage. As a result, the armature coil voltage 39a rises quickly. Thereby, the generation of a reduced torgue is eliminated. In addition, since the coil is energized substantially with square waves, an output torque is increased.

摘要： PURPOSE:To restrain ripples and vibrations by a method wherein first two opposite salient poles and second two opposite salient poles out of four salient poles for a rotor are arranged and installed in such a way that phases in their directions of rotation are changed. CONSTITUTION:In two sets of three-phase armature coils, 24 slots 3a, 3b,..., 3x are arranged and installed at equal separation intervals on the inner circumferential face of a fixed armature 3. On the other hand, four salient poles 1a, 1b, 1c, 1d in a width of 150 deg. each (electrical angle) are arranged and installed alternately on the outer circumferential face of a rotor 1 at three separation intervals and in widths of four separation intervals of the slots 3a, 3b,..., 3x for the fixed armature 3. Then, energization whose phase difference is at 1/2 or 1/3 of the slot separation intervals is made for the armature coils of two phases. Then, the relative positions of the slots 3a, 3b,..., 3x are shifted by 1/2 of their separation intervals by tip ends 1A and 1C as well as 1b and 1D in the directions of rotation of the salient poles 1a, 1b, 1c, 1d, and torque ripples are offset.

摘要： PURPOSE:To obtain a brushless motor, a reluctance motor and a stepping motor which have a high speed, a high torque and excellent efficiency. CONSTITUTION:At the time when electrification of one armature coil 32a is stopped through the intermediary of one switching element on the positive voltage side, magnetic energy is made to flow in a capacitor 46a of a small capacity, charged and held therein at a high voltage and a current falls quickly. An impression voltage on the next armature coil 32b becomes high due to charging of a capacitor 46b and, therefore, the current rises quickly. Only with the static energy charged in the capacitor, however, the rise of the electrification of the armature coil is insufficient due to a copper loss of the armature coil and an iron loss of a magnetic core. Therefore the electrification current is kept at a set value by a chopper circuit and a part of the magnetic energy of the magnetic core of the armature coil is charged and held in the capacitor 46 of the small capacity at the time of the stop of the electrification so that it may correspond to a chopper frequency. Thereby an energy loss due to the iron loss and the copper loss at the time of alternation of the electrification of the armature coils 32 is supplemented and the rise of the electrification current is made quick.
