摘要： A motor includes a housing, a rotor and a stator. The housing includes a shaft tube having a free end. The rotor includes a shaft rotatably extending through the bearing and having an annular groove. The stator includes an assembling hole receiving the shaft tube. The stator includes an upper bobbin, a lower bobbin, a plurality of silicon steel plates and a winding. The upper bobbin includes a plurality of pressing plates annularly, each having first and second abutting portions. The first abutting portion has a first end connecting to the upper bobbin, and a second end abutting against a top surface of the bearing. The free end is lower than the first end but higher than the second end. The first abutting portion is spaced from the shaft tube and abuts only on the bearing. The second abutting portion extends from the first abutting portion into the annular groove.

摘要： A motor includes a housing, a rotor and a stator. The housing includes a shaft tube receiving a bearing. The rotor includes a shaft rotatably extending through the bearing and having an annular groove in a neck shape formed on an outer periphery thereof. The stator includes an assembling hole receiving the outer periphery of the shaft tube, with the stator including an upper bobbin, a lower bobbin, a plurality of silicon steel plates sandwiched between the upper and lower bobbins, and a winding wound around the plurality of silicon steel plates. The upper bobbin includes an abutting member formed on an inner periphery thereof. The abutting member abuts against the bearing and extends into the annular groove of the shaft to avoid the bearing and the rotor disengaging from the shaft tube. Consequently, assembling convenience and rotating stability of the motor are enhanced.
