    • A current-carrying apparatus for a direct-current motor is composed of a commutator, which has a plurality of divided portions arranged in a circle-circumferential direction of the commutator, for commutating a direct current, which is supplied from an electric power source through a first brush, to N commutated currents having different phases from each other one after another, and N slip rings, which are separated from each other in an annulus ring shape to be concentrically arranged in a circumferential area of the commutator and are respectively and electrically connected with one divided portion of the commutator, for respectively carrying one of the commutated currents obtained in the commutator to a corresponding coil of a stator through a second brush. Therefore, the reliability for the current-carrying apparatus can be improved. Also, a valve apparatus using a current-carrying apparatus for a direct-current motor is composed of a stator in which a prescribed number of coils are arranged at almost equal intervals in a circle-circumferential direction of each of a plurality of stator cores, a rotor in which a plurality of permanent magnet magnetic poles are arranged on an outer circumferential surface of the rotor so as to place each permanent magnet magnetic pole at a position corresponding to that of the corresponding coil of the stator, a current-carrying means for commutating a direct current, which is supplied from an electric power source through the rotor, to a commutated current by using the rotor and for carrying the commutated current to each coil of the stator, a shaft member, which is arranged in a center portion of the rotor and is movable in an axial direction of the shaft member according to the rotation of the rotor, and a valve member for performing an open operation and a close operation according to the movement of the shaft member. Therefore, a moment of inertia in the rotor can be lowered, and a valve apparatus can be obtained with superior response for a valve open and close operation.
    • 直流电动机的通电装置由换向器构成,该换向器具有沿换向器的圆周方向排列的多个分割部,用于将从电源供给的直流电 一个第一电刷,一个接一个地彼此具有不同相位的N个换向电流,以及N个滑环,它们以环形环状彼此分开,以便同心地布置在换向器的圆周区域中,并且分别且电气地 与换向器的一个分开的部分相连接,用于分别通过第二电刷将在换向器中获得的换向电流中的一个换向到定子的相应线圈。 因此,可以提高通电装置的可靠性。 另外,使用直流电动机的通电装置的阀装置,由多个定子铁心的圆周方向上大致等间隔地配置有规定数量的线圈的定子, 其中多个永磁体磁极布置在转子的外周表面上以便将每个永磁体磁极放置在与定子的对应线圈的位置相对应的位置处的转子;用于电流传输的载流装置, 通过转子将从电源供给的直流电通过转子转换成换向电流,并将换向电流输送到定子的每个线圈;轴部件,布置在定子的中心部分 所述转子能够根据所述转子的旋转而沿所述轴部件的轴向移动;以及阀部件,其用于执行打开操作和关闭操作 轴构件的运动。 因此,可以降低转子中的转动惯量,并且可以获得阀装置,该阀装置对于阀打开和关闭操作具有优异的响应性。 <图像>
