  • Patent number: 9667104
    Abstract: A three-phase motor structure includes a sectional stator, a winding set, a circuit board and an inner rotor. The sectional stator includes a detachable pole set which has a plurality of pole teeth. Before being assembled, the winding set is wound on the pole pins of the detachable pole set. The circuit board is mounted on the sectional stator and electrically connects with the winding set. The inner rotor extends through the sectional stator when assembled.

  • Patent number: 8954114
    Abstract: A communication device is provided with a processing unit. The processing unit determines whether at least one elementary file in a single subscriber identity card is required to be read out. If so, the processing unit activates one subscriber identity module instance in the subscriber identity card for the elementary file, and reads the elementary file from the subscriber identity card.
