    • The motor includes a cylindrical rotor core, a plurality of magnets axially penetrated in the rotor core, a pair of separation-preventing plates installed at both ends of the rotor core, and at least one fixing member to fix the separation-preventing plates to the rotor core. The fixing member includes a rod portion extending in an axial direction of the rotor core to be disposed on an outer circumferential surface of the rotor core, and supporting portions bent from both ends of the rod portion and used to support the separation-preventing plates. The separation-preventing plates can be fixed to the rotor core by the fixing member disposed on the outer circumferential surface of the rotor core. The fixing member has no risk of hindering the flow of magnetic flux generated from the magnets, resulting in an improvement in the performance of the motor.

    • A rotor for a synchronous motor includes a main core which is formed with a shaft hole disposed in a center area thereof, a plurality of inductive conductor slots arranged along an outer area thereof, and a plurality of magnet slots each arranged between the shaft hole and the inductive conductor slots; an inductive conductor which is inserted into each inductive conductor slot; a first and a second permanent magnet units which each have at least one first permanent magnet and at least one second permanent magnet having different polarities, the first permanent magnet and the second permanent magnet being inserted into the magnet slots and being disposed opposite to each other with the shaft hole being interposed therebetween; and a magnetic flux loss prevention member which is disposed between the first permanent magnet unit and the second permanent magnet unit and prevents loss of magnetic flux, intervals between the inductive conductor slots become small as the inductive conductor slots go from centers of the first and second permanent magnet units to the magnetic flux loss prevention member. Thus, intervals of inductive conductor slots in which inductive conductors are inserted become small as the inductive conductor slots go from centers of permanent magnet units to a magnetic flux loss prevention member, and thus, torque ripple generated in a portion where polarities of permanent magnets are changed in driving a synchronous motor is prevented, thereby reducing vibrations and noises.
    • 一种用于同步电动机的转子包括:主芯,其形成有设置在其中心区域的轴孔;多个感应导体槽,沿着其外部区域布置;多个磁体槽,分别设置在所述轴孔和 感应导体槽; 一个插入每个感应导体槽的感应导体; 第一和第二永磁体单元,每个具有至少一个第一永磁体和至少一个具有不同极性的第二永磁体,所述第一永磁体和所述第二永磁体插入所述磁槽中并彼此相对布置 轴孔插入其间; 以及防磁部件,其设置在所述第一永久磁铁单元与所述第二永磁体单元之间,并且防止磁通量的损失,所述感应导体槽之间的间隔随着所述第一和第二永磁体单元的中心而变小, 永磁体单元连接到磁通量损失部件。 因此,由于感应导体槽从永久磁铁单元的中心向磁阻防止部件移动,所以在其中插入感应导体的感应导体槽的间隔变小,因此在永磁体的极性部分产生的转矩脉动为 防止驱动同步电动机的变化,从而减少振动和噪声。

    • A method of activating only a specific module in a mobile communication terminal having a plurality of additional modules is provided. In the method, it is checked if a first hot key is input in order to activate only the specific module. If the first hot key is input, power is supplied to a module corresponding to the first key and the module is activated. Only specific additional functions such as an MP3 player or a digital camera can be used while a communication module is inactivated. Thus, additional functions of the mobile communication terminal can be used without being restricted by time and space. In addition, the modules can be used without a SIM or UIM card in a GSM or CDMA terminal.
    • 提供了一种在具有多个附加模块的移动通信终端中仅激活特定模块的方法。 在该方法中,检查是否输入了第一个热键,以仅激活特定的模块。 如果输入了第一个热键,则将电源提供给与第一个密钥对应的模块,并激活模块。 在通信模块未激活时,只能使用特定的附加功能,例如MP3播放器或数码相机。 因此,可以使用移动通信终端的附加功能而不受时间和空间的限制。 另外,这些模块可以在GSM或CDMA终端中没有SIM或UIM卡的情况下使用。

    • A method for notifying of a low battery status in a mobile terminal is disclosed in which remaining battery power is detected while the terminal communicates with another party. If the detected battery power is determined to be reduced to a low battery status, a message for notifying the other party of communication termination due to a low battery status is transmitted the other party. Accordingly, if a mobile terminal enters a low battery status while communicating with the other party, the mobile terminal notifies the other party of communication termination due to the low battery status before forcibly terminating the communication. Thus, the other party can know why the communication was terminated, thereby preventing the other party from attempting unnecessary reconnection.
    • 公开了一种用于在移动终端中通知低电量状态的方法,其中在终端与另一方通信时检测到剩余电池电力。 如果检测到的电池电量被确定为降低到低电量状态,则由另一方发送用于通知对方由于电池电量不足而导致通信终止的消息。 因此,如果移动终端在与另一方进行通信时进入低电池状态,则在强制终止通信之前,移动终端由于电池电量不足而通知对方的通信终止。 因此,对方可以知道为什么通信被终止,从而防止对方尝试不必要的重新连接。
