  • Publication number: 20040239198
    Abstract: An axial tube assembly of a motor includes an axial tube around which a stator assembly is mounted, an engaging member, and a sleeve in which a bearing is mounted. The engaging member includes a base and a plurality of resilient legs projecting from the base. Each resilient leg has a hook on a distal end thereof. The base of the engaging member is engaged with and thus seals a bottom end of an axial hole of the axial tube. The sleeve is mounted in the engaging member and has a base portion. The hook of each resilient leg is pressed outward to thereby retain the stator assembly in place when the sleeve and the engaging member are received in the axial tube, with the resilient legs of the engaging member together holding the sleeve to thereby allow tight engagement between the sleeve and the bearing.

  • Patent number: 6741047
    Abstract: A dual current-limiting circuit for a dc brushless motor includes an over-current detective circuit, an operation detective circuit, and a current-limiting circuit. The over-current detective circuit produces a voltage signal used to determine whether an over-current has been input to the motor. The operation detective circuit also produces a voltage signal used to determine whether the motor is being operated in a normal manner. The current-limiting circuit decides to turn on a first switch of a first current-limiting circuit and to subsequently turn on a second switch of a second current-limiting circuit depending upon the two voltage signals. The current-limiting circuit is capable of suppressing current passing through a coil at a low voltage level, which is inadequate to damage a driver circuit and still adequate to restart the motor if an abnormal input current is eliminated.
