    • A miniature pump includes a pump casing (1) defining therein an inner space with an inlet (104) and an outlet (110) both being in flow communication with the inner space, a liquid circulating unit (2) having an impeller (26) received in the inner space, a motor driving unit (3) received in the inner space to drive the impeller to rotate, and a partition wall (14) arranged in the pump casing to space the liquid circulating unit and the motor driving unit. The impeller carries a first permanent magnet (260). The motor driving unit includes a motor having a rotor (34) and a second permanent magnet (340) attached to the rotor. The second permanent magnet corresponds to the first permanent magnet with a flux gap formed therebetween. Each of the first and second permanent magnets has a plurality of alternating N and S poles.
    • 微型泵包括:泵壳体(1),其中限定有具有入口(104)和与内部空间流动连通的出口(110)的内部空间;具有叶轮(26)的液体循环单元(2) 在所述内部空间中容纳有容纳在所述内部空间中以驱动所述叶轮旋转的马达驱动单元(3),以及布置在所述泵壳体中以间隔所述液体循环单元和所述马达驱动单元的分隔壁(14)。 叶轮承载第一永久磁铁(260)。 马达驱动单元包括具有附接到转子的转子(34)和第二永磁体(340)的马达。 第二永磁体对应于在其间形成有磁通间隙的第一永久磁铁。 第一和第二永久磁铁中的每一个具有多个交替的N极和S极。
