Description

Technical Field

[0001] The utility model belongs to the field of stator and rotor, and relates to a stator and rotor, in particular to a high-efficiency water pump stator and rotor. Background Art

[0002] The working principle of the motor stator and rotor of a water pump is that when an electric current is applied to the stator to generate a rotating magnetic field, this rotating magnetic field cuts the coil of the rotor device, causing the rotor to also generate a magnetic field. The two magnetic fields of the stator and rotor interact with each other, thus making the water pump motor rotate and the water pump work.

[0003] In actual situations, the structure of the water pump stator and rotor is relatively complex, and there are defects in the design of the stator structure. The stator winding structure needs to be individually wound and welded manually, which increases the labor cost and seriously affects the production efficiency. At the same time, when the water pump stator and rotor work, it will generate high temperature, causing the shaft core to get hot. If timely heat dissipation treatment is not carried out, it will affect the working life of the stator and rotor and lead to the scrapping of the entire water pump. Summary of the Invention

It is characterized in that the transmission shaft is provided with a hollow structure, and a number of through holes for facilitating the rapid volatilization of heat are opened on the transmission shaft;

[0023] As Figure 1 , Figure 2 , Figure 3 , Figure 4 shown, for this high-efficiency water pump stator and rotor, there are a stator assembly, a rotor assembly, a motor housing, and a transmission shaft 1 for installing the stator assembly and the rotor assembly and for power transmission. The transmission shaft 1 is provided with a hollow structure, and a number of through holes 2 facilitating the rapid volatilization of heat are opened on the transmission shaft 1. The stator assembly includes a number of winding blocks 3 for winding leads and a silicon steel core 4 facilitating the installation of the winding blocks 3. The number of winding blocks 3 and the silicon steel core 4 are arranged in a split splicing structure. The rotor assembly includes a rotor iron ring 5 sleeved outside the transmission shaft 1, a number of permanent magnets 6 embedded outside the rotor iron ring 5, and heat dissipation fins 7 for improving the heat dissipation intensity. The motor housing includes an upper housing 8 and a lower housing 9, and the upper housing 8 and the lower housing 9 are connected by internal and external thread cooperation. A number of heat dissipation holes 10 facilitating the rapid heat dissipation of the internal air are respectively opened at the end parts of the upper housing 8 and the lower housing 9. A limiting step 11 for installing the silicon steel core 4 is provided inside the lower housing 9. The silicon steel core 4 is limited by the structural cooperation of the upper housing 8 and the lower housing 9, and axially limits the number of winding blocks 3.

[0024] The above structure is reasonably designed. With the structural cooperation of the transmission shaft 1 with a hollow structure, the through holes 2 and the heat dissipation holes 10, the internal part of the stator and rotor can be effectively cooled rapidly, realizing the rapid heat dissipation inside the main body of the stator and rotor, greatly extending the service life of the stator and rotor. At the same time, by using the structural cooperation of the winding blocks 3, the silicon steel core 4 and the motor housing, the clamping and limiting of the winding blocks 3 can be effectively realized. The winding process is convenient and simple, reducing the production and manufacturing difficulty, effectively reducing the labor force of manual winding, and improving the production efficiency.

[0025] To elaborate further, in order to facilitate the split splicing structure of the number of winding blocks 3 and the silicon steel core 4, a number of wedge-shaped grooves 12 facilitating the clamping and limiting of the winding blocks 3 are opened on the inner peripheral wall of the silicon steel core 4. A clamping member 13 engaging and connecting with the wedge-shaped groove is provided on each of the number of winding blocks 3. The cross sections of the end part of the clamping member 13 and the bottom of the wedge-shaped groove 12 are both in an inverted "ladder" shape structure, and the number of winding blocks 3 is axially limited by the upper housing 8.

[0026] To elaborate further, in order to facilitate the rotational operation of the rotor assembly and the transmission shaft 1, there is a gap between the stator assembly and the rotor assembly.

[0027] To elaborate further, in order to improve the heat dissipation efficiency of the rotor assembly, a number of permanent magnets 6 are arranged at intervals in a circumferential direction along the outside of the rotor iron ring 5, and heat dissipation fins 7 are connected between two adjacent permanent magnets 6.

[0028] The specific embodiments described herein are merely illustrative of the spirit of the present utility model. Those skilled in the art to which the present utility model pertains can make various modifications or supplements to the described specific embodiments or use similar means for substitution, but will not deviate from the spirit of the present utility model or exceed the scope defined by the appended claims.

[0029] Although terms such as drive shaft 1, through hole 2, winding block 3, silicon steel core 4, rotor iron ring 5, permanent magnet 6, heat sink 7, upper housing 8, lower housing 9, heat dissipation hole 10, limiting step 11, wedge-shaped groove 12, and clamping member 13 are used more frequently herein, the possibility of using other terms is not excluded. The use of these terms is only for more conveniently describing and explaining the essence of the present utility model; interpreting them as any additional limitation is contrary to the spirit of the present utility model.
