    摘要： A drive motor has a shaft supported by a casing to be rotatable and movable in the axial direction over a predetermined stroke. A portion of the shaft is utilized in order to form a rotary motor section for rotating the shaft, and another portion of the shaft is utilized in order to form an electromagnetic plunger section for moving the shaft in the axial direction. The rotary motor section and the electromagnetic plunger section are integrally built in the casing. The drive motor is used in a drive apparatus for a pre-plasticization-type injection molding machine. The front end of the shaft is connected to the rear end of a screw disposed within a barrel of a plasticizing unit of molding machine. Through axial movement of the shaft, a resin passage of the barrel is opened and closed by a valve portion provided at the front end of the screw.

    摘要： Linear motor includes a moving member tapered relative to a traveling direction to provide a surface slanted relative to the traveling direction toward one end of the moving member, a stator having a surface that is opposed to the slanted surface of the first member and slanted relative to the traveling direction at an angle corresponding to the slanted angle of the slanted surface of the moving member, a field pole producing section for producing field poles on the slanted surface of the moving member, and an armature section provided on the stator and including armature windings so as to produce electromagnetic poles corresponding to electric currents passed through the armature windings. Thus, the moving member is caused to move relative to the stator, by exciting the armature windings to produce a linearly moving magnetic field. Due to the tapered configuration, magnetic attraction produced between the moving member and the armature core is partly split in the traveling direction, which leads to an increased thrust.

    摘要： Rotary synchronous machine includes a stator and a rotor. The stator includes a magnetic field core and an armature core magnetically separated from each other. The rotor includes a plurality of magnetic substance segments which are magnetically separated from each other in a direction of rotation but are magnetically coupled with both of the magnetic field core and armature core. The rotor and magnetic field core are arranged to cause an axial thrust to the rotor depending on the intensity of electric currents passed through filed windings. Namely, the rotor and magnetic field core are arranged in such a manner that magnetic attraction (magnetic coupling) occurs between the rotor and the magnetic field core in a same direction as a rotational axis or at a predetermined non-normal angle relative to the rotational axis. Thus, thrust is produced based on the magnetic attraction between the rotor and the magnetic field core, and this thrust corresponds to the intensity of the electric currents passed through filed windings. Consequently, a traveling position of the rotor in the axial direction can be controlled by providing the magnetic field cores adjacent to opposite sides of the rotor and appropriately controlling the intensity of the filed currents.

    摘要翻译： 旋转同步电机包括定子和转子。 定子包括磁场铁心和磁性地彼此分离的电枢铁芯。 转子包括多个磁性体段，它们在旋转方向上彼此磁分离，但与磁场磁芯和电枢磁芯磁耦合。 转子和磁场芯被布置成根据通过磁场绕组的电流的强度引起转子的轴向推力。 也就是说，转子和磁场铁芯以这样一种方式被布置，使得在转子和磁场铁芯之间沿与旋转轴线相同的方向或相对于旋转轴线以预定的非正常角度发生磁吸引（磁耦合） 轴。 因此，基于转子和磁场磁芯之间的磁吸引力产生推力，并且该推力对应于通过磁场绕组的电流的强度。 因此，可以通过设置与转子的相对侧相邻的磁场铁芯并适当地控制励磁电流的强度来控制转子在轴向上的行进位置。

    摘要： A motor drive apparatus is provided in an injection molding machine in order to supply electrical energy to a motor. The motor drive apparatus includes an electricity accumulation unit for accumulating electrical energy; and an electricity accumulation circuit for accumulating in the electricity accumulation unit electrical energy regenerated from the motor during a deceleration period of the motor and for supplying the electrical energy accumulated in the electricity accumulation unit to the motor during an acceleration period of the motor. By virtue of the above-described structure, when a heavy member such as a screw of an injection apparatus or a movable platen of a mold clamping apparatus is moved at high speed in each molding cycle, at the beginning of movement or during an acceleration period of the motor, the electricity accumulation circuit adds the electrical energy accumulated in the accumulation unit to electrical energy that is supplied from a power source to the motor, and during a deceleration period of the motor, electrical energy regenerated from the motor is accumulated in the accumulation unit.
