Problems solved by technology

The air cooling system of this design is actually applied to products, especially directly used for small power motors. The cooling effect is not ideal. When the temperature rise of the motor winding is too high, the electromagnetic design can only be modified, so as to increase more material costs.

Abstract

The invention provides a small-power motor with an internal air-cooling system. The motor comprises a rotary shaft, a rotor, a stator, an end cover and a machine base, wherein the rotor is provided with a rotor iron core and internal fan blades extended outward from the end part of the rotor along the axial direction; and the stator is provided with a stator iron core and a stator winding, wherein the end part of the stator winding is wound around the internal fan blades of the rotor. The motor is characterized in that: the axial outer ends of the internal fan blades are connected with a surface of revolution of the rotary shaft. Due to the adoption of the design, the air efficiency of the internal fan is improved, and all circulation air flow is made to pass through the end part of the rotor winding, so that the temperature rise of the motor winding is lowered, and the structure is simple and the cost is low.

Description

technical field [0001] The invention relates to a low-power motor, especially its cooling structure, which belongs to H02K9 / 06 in the International Patent Classification Table. Background technique [0002] Cage induction motors have a long history. The traditional design of closed or protected small and medium-sized cage induction motors can be found in "Motor Design" (Chen Shikun, Xi'an Jiaotong University, Mechanical Industry Press, Beijing 1st Edition, 1982), and its typical structure is shown in Figure 8-1 in P164-165 of this book 3 and Figure 8-4. The air cooling system of this design is actually applied to products, especially directly used for small power motors. The cooling effect is not ideal. When the temperature rise of the motor winding is too high, the electromagnetic design can only be modified, so as to increase more material costs. [0003] The terms involved in the present invention can also be seen in the national standard GB / T 2900.25-94 "Electrotechnic...
