A rotor applied in a dust collector motor comprises a rotary shaft (1), rotor magnetic steel (2), a load blade (3), two bearings (4, 5) between the rotor magnetic steel and the load blade, and a pre-tightening spring (6) used for providing precompression for the bearings on two sides. The bearings are arranged between the load blade and the rotor magnetic steel, so that the motor structure is simplified, the overall size of the motor is reduced, and the machining and manufacturing of the dust collector motor are facilitated. As the pre-tightening spring is arranged between the two bearings, the bearings are close to the load blade as much as possible under the effect of pre-tightening force, end swinging oscillation of the rotor is reduced, and noises are lowered. By means of cooperation of the two bearings and the pre-tightening spring, operating stability is ensured, and the use of materials is reduced effectively. Grooves (11) are formed in the outer side of the rotary shaft, and the rotary shaft and components on the rotary shaft can be fixed by filling the grooves with adhesives. Meanwhile, the grooves can also be arranged to avoid overflowing of the adhesives, and connection stability of the rotary shaft and the components on the rotary shaft is ensured. |
