    • Disclosed is a pole-change type motor that provides a variable-speed (two-pole or four-pole type) operation system capable of reducing the load of the motor of the normal operation system and improving the cooling efficiency. In case of a quick operation, the motor switches over to the two-pole type according to the control of a relay section. At this time, the load of the motor is reduced by offsetting an abnormal magnetic field distribution formed due to the same polarity of adjacent main windings using compensation windings of an opposite polarity. If the quick operation is needed, the motor switches over to the two-pole type, and operates at a high speed to achieve the quick cooling. Then, if a standard operation is possible with the lapse of the predetermined time, the motor switches over to the four-pole type, and operates at a low speed to achieve an effective cooling.
    • 公开了一种变极型电动机,其提供能够降低正常操作系统的电动机的负载并提高冷却效率的变速(二极或四极型)操作系统。 在快速操作的情况下,电机根据继电器部分的控制切换到两极型。 此时,通过使用相反极性的补偿绕组来抵消由于相邻主绕组的相同极性而形成的异常磁场分布而减小电动机的负载。 如果需要快速操作,电机切换到两极型,高速运转,实现快速冷却。 然后,如果经过预定时间可以进行标准操作,则电动机切换到四极型,并且以低速运行以实现有效的冷却。

    • The present invention discloses a sound converter with an enclosure which utilizes an outer space to expand a resonance space. The sound converter with the enclosure includes a frame being equipped with a magnetic circuit for forming a magnetic field in a predetermined gap, a voice coil at least partially positioned in the gap, a diaphragm adhered to the voice coil and inserted into a diaphragm seating portion of the frame, a protector formed at the upper portion of the diaphragm, and an enclosure case coupled to the frame, for defining the inner space of the enclosure which is the resonance space. A vent is provided at the enclosure case so that the inner space of the enclosure can communicate with the outer space. This configuration can secure a wide resonance space.
    • 本发明公开了一种具有外壳的声音转换器,该外壳利用外部空间来扩展共振空间。 具有外壳的声音转换器包括配备有用于形成预定间隙中的磁场的磁路的框架,至少部分地定位在间隙中的音圈,粘附到音圈并插入隔膜座部分的隔膜 的框架,形成在隔膜的上部的保护器和联接到框架的外壳,用于限定作为共振空间的外壳的内部空间。 在外壳处设置通风口,使得外壳的内部空间能够与外部空间连通。 这种配置可以确保广泛的共振空间。
