Description

Technical Field

[0001] This utility model relates to a stator winding, and more particularly to a stator winding for an axial magnetic field motor, belonging to the technical field of axial magnetic field motors. Background Technology

[0002] Axial magnetic field motors are a new type of motor that differs from traditional radial magnetic field motors, offering unique advantages in structure and performance. Their magnetic field is parallel to the motor shaft and distributed axially, resulting in a shorter axial dimension and a larger radial dimension, leading to a flatter and more compact structure. Compared to traditional radial magnetic field motors, axial magnetic field motors have higher torque density, enabling them to output greater torque in a smaller volume, and offer superior energy conversion efficiency, effectively reducing energy consumption at the same power output. Axial magnetic field motors have broad application prospects in fields such as new energy vehicles, aerospace, and industrial robots.

[0003] During the operation of existing magnetic field motors, the stator windings generate a large amount of heat due to copper losses, iron losses, etc. Because of the compact structure and dense coil arrangement of the stator windings, it is difficult to dissipate the heat effectively. Traditional heat dissipation methods, such as natural convection or simple air cooling, are insufficient to meet the heat dissipation requirements of high power density motors, especially when the motor operates under high load for a long time, where heat continues to accumulate and the temperature rises sharply. Therefore, an axial magnetic field motor stator winding is proposed. Utility Model Content

[0004] In view of this, the present invention provides an axial magnetic field motor stator winding to solve or alleviate one of the technical problems existing in the prior art, and at least provides a beneficial alternative.

[0005] The technical solution of this utility model embodiment is implemented as follows: an axial magnetic field motor stator winding includes a stator assembly, wherein the stator assembly includes a stator bracket, a connecting plate, a liquid inlet pipe, a liquid inlet channel, a heat exchange channel, a liquid return channel, and a liquid return pipe;

[0006] A connecting plate is fixedly connected to the outer wall of the stator support. The top of the connecting plate is connected to an inlet pipe and a return pipe. The inside of the connecting plate is provided with an inlet channel and a return channel. One end of the inlet pipe is connected to the inlet channel, and one end of the return pipe is connected to the return channel. The inside of the stator support is provided with several heat exchange channels, which are connected to the inlet channel and the return channel. One end of the inlet pipe and the return pipe is connected to a radiator. The radiator is installed outside the axial magnetic field motor housing. The radiator cools the high-temperature coolant in the return pipe. At the same time, the radiator integrates a circulation pump, which continuously circulates the coolant. Coolant is sent into the stator support through the inlet pipe. The coolant enters the heat exchange channel through the inlet channel and absorbs the heat generated by the stator winding body during operation, thereby reducing the overall temperature of the stator winding. The number of heat exchange channels can be adjusted according to the size of the stator support.

[0007] A further preferred embodiment: the outer side wall of the stator support is symmetrically fixedly connected with a fixing plate, and the inner side wall of the fixing plate is symmetrically threadedly connected with fixing bolts.

[0008] A further preferred embodiment: the stator support has a through hole inside.

[0009] A further preferred embodiment: stator teeth are uniformly fixedly connected to one side of the stator support.

[0010] A further preferred embodiment: the outer wall of the stator teeth is provided with a stator winding body.

[0011] A further preferred embodiment: a rotor assembly is provided on one side of the stator assembly, the rotor assembly including an output shaft, a connecting rod and a rotor support;

[0012] Connecting rods are uniformly fixedly connected to the outer side wall of the output shaft, and a rotor bracket is fixedly connected to one end of each connecting rod.

[0013] A further preferred embodiment: one end of the output shaft has a through hole.

[0014] A further preferred embodiment: permanent magnets are uniformly fixedly connected to the inner sidewall of the rotor support.

[0015] The present invention has the following advantages due to the adoption of the above technical solution:

[0016] I. This utility model introduces coolant into the stator support through the inlet pipe, and absorbs the heat generated by the stator winding body during operation through the heat exchange channel, thereby reducing the overall temperature of the stator winding, improving the heat dissipation effect of the stator winding, and meeting the heat dissipation requirements of high power density motors.

[0017] Second, by setting multiple heat dissipation channels inside the stator support, this utility model can increase heat exchange efficiency, avoid continuous heat accumulation, and prevent a sharp rise in temperature.

[0025] In the following description, only certain exemplary embodiments are briefly described. As those skilled in the art will recognize, the described embodiments can be modified in various ways without departing from the spirit or scope of this invention. Therefore, the drawings and description are considered exemplary in nature and not restrictive.

[0026] The embodiments of this utility model will now be described in detail with reference to the accompanying drawings.

[0027] like Figures 1-4As shown, this utility model embodiment provides an axial magnetic field motor stator winding, including a stator assembly 10, which includes a stator bracket 11, a connecting plate 17, a liquid inlet pipe 18, a liquid inlet channel 19, a heat exchange channel 110, a liquid return channel 111, and a liquid return pipe 112.

[0028] A connecting plate 17 is fixedly connected to the outer wall of the stator support 11. The top of the connecting plate 17 is connected to an inlet pipe 18 and a return pipe 112. An inlet channel 19 and a return channel 111 are provided inside the connecting plate 17. One end of the inlet pipe 18 is connected to the inlet channel 19, and one end of the return pipe 112 is connected to the return channel 111. Several heat exchange channels 110 are provided inside the stator support 11. The heat exchange channels 110 are connected to the inlet channel 19 and the return channel 111. One end of the inlet pipe 18 and the return pipe 112 are connected to a radiator, which is installed on... The high-temperature coolant in the return pipe 112 is cooled by a radiator outside the axial field motor housing. At the same time, a circulation pump is integrated on the radiator to continuously circulate the coolant. The coolant is then fed into the stator support 11 through the inlet pipe 18. The coolant enters the heat exchange channel 110 through the inlet channel 19. The heat exchange channel 110 absorbs the heat generated by the stator winding body 16 during operation, thereby reducing the overall temperature of the stator winding and improving the heat dissipation effect of the stator winding. The number of heat exchange channels 110 can be adjusted according to the size of the stator support 11.

[0029] In this embodiment, specifically: a fixing plate 12 is symmetrically fixedly connected to the outer side wall of the stator bracket 11, and a fixing bolt 13 is symmetrically threadedly connected to the inner side wall of the fixing plate 12. The stator bracket 11 is fixed to the motor housing by the fixing bolt 13.

[0030] In this embodiment, specifically: the stator support 11 has a through hole 14 inside.

[0031] In this embodiment, specifically: stator teeth 15 are uniformly fixedly connected to one side of the stator support 11, and the stator teeth 15 are used to wind the stator winding.

[0032] In this embodiment, specifically: a stator winding body 16 is provided on the outer wall of the stator tooth 15. After the stator winding body 16 is energized, it generates a magnetic field, which causes the permanent magnet 24 to rotate through the magnetic force.

[0033] In this embodiment, specifically: a rotor assembly 20 is provided on one side of the stator assembly 10, and the rotor assembly 20 includes an output shaft 21, a connecting rod 22 and a rotor support 23;

[0034] Connecting rods 22 are uniformly fixedly connected to the outer wall of the output shaft 21. One end of the connecting rod 22 is fixedly connected to the rotor bracket 23. The output shaft 21 is driven to rotate through the rotor bracket 23 and the connecting rod 22, so that the axial magnetic field motor works.

[0035] In this embodiment, specifically: one end of the output shaft 21 passes through the through hole 14, and the output shaft 21 is fixed on the bearing seat of the motor housing. The through hole 14 provides space for the installation of the output shaft 21.

[0036] In this embodiment, specifically: permanent magnets 24 are uniformly fixedly connected to the inner sidewall of the rotor support 23.

[0037] When this invention is in operation: after the stator winding body 16 is energized, it generates a magnetic field, which causes the permanent magnet 24 to rotate. This rotation is caused by the rotor support 23 and the connecting rod 22, which in turn drives the output shaft 21 to rotate, thus enabling the axial magnetic field motor to operate. Coolant is introduced into the stator support 11 through the liquid inlet pipe 18. The coolant then enters the heat exchange channel 110 through the liquid inlet channel 19. The heat exchange channel 110 absorbs the heat generated by the stator winding body 16 during operation, thereby reducing the overall temperature of the stator winding and improving the heat dissipation effect of the stator winding. This meets the heat dissipation requirements of high power density motors. By setting multiple sets of heat exchange channels 110 inside the stator support 11, the heat exchange efficiency can be increased, preventing the continuous accumulation of heat and preventing a rapid increase in temperature.

[0038] The above description is merely a specific embodiment of this utility model, but the protection scope of this utility model is not limited thereto. Any person skilled in the art can easily conceive of various variations or substitutions within the technical scope disclosed in this utility model, and these should all be included within the protection scope of this utility model. Therefore, the protection scope of this utility model should be determined by the protection scope of the claims.
