This type of motor is a high-density motor, and there are limitations on the temperature rise of the motor. The conventional motor air duct structure is a beam air duct structure, and the air duct is radially arranged pointing to the center. The air duct of this structure occupies a large area, the air duct is relatively complex, and the ventilation and heat dissipation effect is low. The conventional motor stator radial ventilation structure can no longer meet the motor temperature rise requirements, so a new structure needs to be developed. Summary of the Utility Model

The radial air duct divides the stator radially into a number of radial air ducts with equal intervals and equal widths. Inner cylinders in the air duct are arranged in an array in the radial air duct, and the height of the inner cylinder in the air duct is the same as that of the air duct partition.

[0009] Further, one row of inner cylinders in the air duct arranged radially is provided at the center of any air duct partition, and the inner cylinders in the air duct are arranged from the air duct partition to the edge of the stator core.
[0010] Further, the width of the air duct partition is 10 cm.
[0011] Further, the diameter of the inner cylinder in the air duct is 3 cm.
[0012] The structure for reducing the temperature rise of a high-density motor stator in a radial ventilation duct of the utility model has the following advantageous effects:
