the motor further comprises a third cylinder 4003, and the third cylinder 4003 is connected with the connecting blade 4004;

the third cylinder 4003 and the second cylinder 4002 are arranged at intervals.

The third cylinder 4003 is added on the basis of the existing high-speed motor, so that the total length of the matching connection of the connecting blade 4004, the third cylinder 4003 and the second cylinder 4002 is increased, the structural strength is improved, the structure is more stable, the material consumption of the bracket 4 can be reduced due to the arrangement of the third cylinder 4003 and the second cylinder 4002 at intervals, and the weight of the motor is reduced; and the complete machine assembler can carry out structural design at the interval between the third cylinder 4003 and the second cylinder 4002 according to the needs to improve the air duct, so that the motor has better structural adaptability; the exposed length of the connecting blade 4004 is reduced, so that the air flow is more concentrated, and the noise generated by air flow diffusion is reduced.

In this example, there are two ways for the airflow to flow, the first is that the fan blades 3 rotate to make the airflow enter the second cylinder 4002 and then enter the third cylinder 4003; in the second step, the fan blades 3 rotate to make the air flow enter the third cylinder 4003 first, and then the air flow blown out from the third cylinder 4003 enters the second cylinder 4002.

The third cylinder 4003 comprises a first end close to the second cylinder 4002 and a second end far from the second cylinder 4002, and the first end is positioned at the other side of the third cylinder 4003; or the first cylinder 4001 extends into the third cylinder 4003, and the second end is located at the other side of the first cylinder 4001.
