摘要： A motor device comprises a motor unit and a reduction unit. The motor unit comprises a yoke which is formed in a generally bottomed cylindrical shape, and a rotor having an armature and a rotary shaft. The reduction unit comprises a gear housing accommodating a reduction gear device for producing an output after reducing rotational speed of the rotor and fixed to the opening of the yoke. A commutator and brushes for the motor unit are disposed in the gear housing which is provided outside the opening of the yoke in the axial direction of the rotary shaft. The gear housing has a flange formed in a square shape, and the brushes are arranged along the diagonal lines of the square shape.

摘要： A motor including a magnet, an armature, a common brush, a low-speed drive brush, and a high-speed drive brush is disclosed. The magnet forms four or more magnetic pole portions. The armature includes a rotation shaft, an armature having fourteen teeth, a coil wound around the teeth, and a commutator having fourteen segments arranged in a circumferential direction of the rotation shaft. The common brush, low-speed drive brush, and high-speed drive brush are spaced apart and arranged in the circumferential direction of the rotation shaft and each have a width in the circumferential direction of the rotation shaft. The number of teeth is the same as the number of segments. When P represents the number of magnetic pole portions of the magnet and S represents the number of teeth, (2S/P) is an odd number. The width of each brush and the location of the brush in the circumferential direction are set so that the three types of brushes, which are the common brush, the low-speed drive brush, and the high-speed drive brush, all do not simultaneously short-circuit two of the segments that are adjacent to each other in the circumferential direction.
摘要翻译：公开了一种包括磁体，电枢，普通电刷，低速驱动电刷和高速驱动电刷的电动机。磁体形成四个或更多个磁极部分。电枢包括旋转轴，具有十四个齿的电枢，缠绕在齿周围的线圈，以及具有沿旋转轴的圆周方向布置的十四个段的换向器。普通刷子，低速驱动刷子和高速驱动刷子在旋转轴的圆周方向上间隔开并且分别在旋转轴的圆周方向上具有宽度。齿数与段数相同。当P表示磁体的磁极部的数量，S表示齿数时，（2S / P）为奇数。每个刷子的宽度和刷子在圆周方向上的位置被设置为使得作为普通刷子，低速驱动刷子和高速驱动刷子的三种类型的刷子都不同时短路在圆周方向上彼此相邻的两个段。

摘要： An electric noise suppressor for a direct current motor comprises a grommet, a choke coil and an electrical terminal. The grommet has an accommodating portion for accommodating the choke coil, an engaging portion for being engaged with a brush holding board of the motor, and a holding portion for holding the terminal. A pair of supporting portions for supporting a pigtail connector are formed to symmetrically protrude from an upper peripheral portion of the accommodating portion. Therefore, the terminal and the pigtail connector are disposed outside the accommodating portion of the grommet, thereby enabling inductance of the choke coil to increase. Further, the pigtail connector, the choke coil and the terminal are restricted from moving and chattering. As a result, the electrical noise suppressor requires less mounting space and is highly reliable.
摘要翻译：用于直流电动机的电噪声抑制器包括索环，扼流圈和电端子。索环具有用于容纳扼流线圈的容纳部分，用于与电动机的电刷保持板接合的接合部分和用于保持端子的保持部分。用于支撑猪尾连接器的一对支撑部分形成为从容纳部分的上边缘部分对称地突出。因此，端子和尾纤连接器设置在护环的容纳部的外侧，从而能够提高扼流圈的电感。此外，尾纤连接器，扼流线圈和端子被限制在移动和颤动。结果，电噪声抑制器需要较少的安装空间并且高可靠性。

摘要： An electric motor has a detachably mounted gear cover and a reduction gear located within the gear cover. One pressure member is inserted into the gear cover through an opening formed through the gear cover and urged against another pressure member to squeeze a choke coil and a connection plate. A high current is flowed through the pressure members for a short time to weld the choke coil and connection plate together through resistive heating.

摘要： A method of making an electric motor where the motor has a reduction gear and a gear cover mounted thereon. An opening is formed through the gear cover at a location corresponding to a connection portion. A pressure member is inserted into the gear cover through the opening and is pressed against another pressure member to squeeze a choke coil and a connection plate. High current may flow through the pressure members for a short time to weld the choke coil and the connection plate together by way of resistive heating.
