PLASTIC-PACKAGED STATOR AND EXTERNAL ROTOR MOTOR COMPRISING THE SAME

摘要

A plastic-packaged stator includes a sleeve base, a plurality of tooth assemblies, and a plastic-packaged body. Each tooth assembly includes an iron core including a plurality of laminated silicon steel sheets, a terminal insulator, and coil windings. The terminal insulator is disposed on one end of the iron core. The coil windings are coiled on the terminal insulator. A plurality of lug bosses is circumferentially disposed at intervals on the outer wall surface of the sleeve base. An inner end of the iron core includes slots. The tooth assemblies are circumferentially disposed on the outer wall surface of the sleeve base. The lug bosses are embedded in the slots. The plastic-packaged body integrates the sleeve base with the tooth assemblies.
