The invention discloses a pan-tilt motor (10), comprising a rotor component (11), a motor shaft (12) and a stator component (13). The motor shaft (12) comprises a shaft body (122), a first end (124) and a second end (126). The first end (124) if fixedly connected to the rotor component (11). The stator component (13) sleeves the periphery of the shaft body (122) and is connected to the motor shaft (12) in a rotating manner through a pair of bearings (15). The pair of bearings (15) are disposed near the first end (124) and the second end (126). The pan-tilt motor (10) also comprises a compressing piece (16) and an elastic body (18). The compressing piece (16) matches with the second end (126), and thereby the stator component (13) is positioned at the motor shaft (12) in an axial direction. The elastic piece (18) and a bearing pad (152) are both disposed between the compressing piece (16) and the bearing (15) adjacent to the second end (126). The bearing pad (152) clings to the bearing (15). The elastic piece (18) is disposed between the bearing pad (152) and the compressing piece (16). The elastic body (18) is elastically deformed through the compressing piece (16), and thereby the axial pretightening force of the pan-tilt motor (10) can be ensured.
