1. An encapsulated stator comprising:
a driving module coupled to a shaft tube, with the driving module including a silicon steel plate unit having an outer periphery, with a coil unit wound around the silicon steel plate unit; a jacket mounted to the outer periphery of the silicon steel plate unit of the driving module, with the jacket including an inner face and an outer face opposite to the inner face, with the inner face of the jacket facing the driving module; and an encapsulant bonded to the driving module, the jacket and the shaft tube, with the encapsulant encapsulating the driving module, with the encapsulant partially encapsulating the outer face of the jacket, with a part of the outer face of the jacket not encapsulated by the encapsulant, with the jacket including a coupling hole receiving the silicon steel plate unit, with the jacket mounted around the outer periphery of the silicon steel plate unit, with the coupling hole having two ends each having an opening, with the openings aligned with each other, with the jacket including first and second end faces respectively surrounding the openings of the coupling hole, with the jacket including a plurality of circumferentially spaced first engagement blocks extending radially inward from the first end face and a plurality of circumferentially spaced second engagement blocks extending radially inward from the second end face, with the plurality of first engagement blocks engaged with an upper end of the silicon steel plate unit, with the plurality of second engagement blocks engaged with a lower end of the silicon steel plate unit, wherein the silicon steel plate unit further comprises a plurality of circumferentially spaced shoe portions, wherein a gap is formed between two adjacent shoe portions, wherein each of the plurality of first circumferentially spaced engagement blocks and each of the plurality of second engagement blocks extend through a respective one of the gaps of the plurality of circumferentially spaced shoe portions when the jacket is fitted around the silicon steel plate unit. |
