A motor's stator unit includes a base (1) and a stator (11). The base (1) has a shaft tube (11). The stator (11) has a silicon steel plate unit (21), an insulation sleeve unit (22) and a coil unit (23). The silicon steel plate unit (21) has an inner circumferential wall forming a through-hole (211). The insulation sleeve unit (22) has an engagement hole (221). The silicon steel plate unit (21) and the insulation sleeve unit (22) are stacked together. The through-hole (211) and the engagement hole (221) are aligned with each other to allow the shaft tube (11) to extend through the through-hole (211) and the engagement hole (221). An enameled copper wire is wound around a predetermined part of the insulation sleeve unit (22) to form the coil unit (23). The insulation sleeve unit (22) is press fitted around an outer circumferential wall of the shaft tube (11) via at least one buffering member (24), so as to prevent the silicon steel plate unit (21) from excessively compressing the shaft tube (11). |
