Description

Technical Field

[0001] This utility model relates to a motor stator support, and more particularly to its heat dissipation structure, belonging to the field of motor technology. Background Technology

[0002] The motor stator is a crucial component of a motor, and the stator bracket is used to mount and secure its various components. Currently, motor heat dissipation design is receiving increasing attention because temperature rise is a key factor limiting motor power and compact design. Existing motor stator brackets have shortcomings, exhibiting poor heat dissipation. Higher-power motors generate more heat; if heat dissipation cannot be improved, it will limit the increase in motor power. Therefore, how to improve the heat dissipation effect of motor stator brackets is a technical problem that urgently needs to be solved by those skilled in the art. Utility Model Content

[0003] To overcome the above-mentioned shortcomings, the purpose of this utility model is to provide a motor stator bracket to improve heat dissipation.

[0004] To achieve the above objectives, the technical solution adopted by this utility model is as follows: a motor stator support, including a housing and several electromagnetic components, with several slots provided on the inner side of the housing, the bottom end of the electromagnetic components being installed in the slots, and the top ends of the several electromagnetic components surrounding each other to form a rotor cavity; several serrations are provided on the top side of the electromagnetic components, and the serrations form a row; the serrations of adjacent electromagnetic components are interlaced to form a bent channel gap.

[0005] A further feature of this invention is that the top of the electromagnetic component is provided with several ventilation slots.

[0006] A further feature of this invention is that the ventilation slot is inclined.

[0007] The present invention is further configured such that: the outer shell includes a metal outer shell and a plastic inner shell, the metal outer shell is stamped to form a first groove and a protrusion, the plastic inner shell is provided with a second groove, and the protrusion is adapted to the second groove; the slot is provided on the inner wall of the plastic inner shell.

[0008] The present invention is further configured such that: a protruding strip is provided on the inner wall of the slot; the electromagnetic component includes a first baffle, a second baffle, an iron core and a conductor coil, the two ends of the iron core are respectively fixedly connected to the first baffle and the second baffle, and the conductor coil is wrapped around the iron core; a fourth groove is provided on the first baffle, and the fourth groove is engaged with the protruding strip.

[0009] The present invention is further configured such that: both ends of the first baffle extend out of the slot, and both ends of the first baffle are provided with a third groove, a wedge is inserted into the third groove, and a threaded hole is provided at the bottom of the third groove, and a bolt is screwed into the threaded hole, the bolt passing through the wedge.

[0010] Compared with the prior art, the beneficial effects of this utility model are as follows: Because several serrations are provided on the top side of the electromagnetic component, forming a row of serrations; the serrations of adjacent electromagnetic components interweave to form bent channel gaps. Air flowing through these bent channel gaps creates turbulent flow, resulting in a larger heat transfer coefficient and enhanced heat transfer effect. This further improves the power of the motor.

[0017] The preferred embodiments of the present invention will now be described in detail with reference to the accompanying drawings, so that the advantages and features of the present invention can be more easily understood by those skilled in the art, thereby making a clearer and more definite definition of the scope of protection of the present invention.

[0018] See appendix Figure 1-5 As shown, a motor stator support includes a housing and several electromagnetic components 5. The housing consists of a metal housing 1 and a plastic liner 2. The metal housing 1 is made of aluminum alloy material and is stamped to form a first groove 3 and a protrusion 4. The plastic liner 2 is made of high-temperature resistant engineering plastic and has a second groove that matches the protrusion 4. The metal housing 1 and the plastic liner 2 are stably connected by the cooperation between the protrusion 4 and the second groove.

[0019] The inner wall of the plastic liner 2 is provided with several evenly distributed slots 18, and the inner wall of the slots 18 is provided with protrusions 7. The electromagnetic assembly 5 includes a first baffle 8, a second baffle 10, an iron core 9, and a coil 11. The two ends of the iron core 9 are fixedly connected to the first baffle 8 and the second baffle 10 respectively by bolts. The coil 11 is wrapped around the iron core 9 and covered with insulating material. The first baffle 8 is provided with a fourth groove 19 that matches the protrusions 7. The electromagnetic assembly 5 is installed in the slots 18 through the engagement of the fourth groove 19 with the protrusions 7.

[0020] The nested structure of a metal outer shell 1 and a plastic inner shell 2 not only saves on manufacturing material costs but also facilitates the fabrication of the slot 18 for connection with the electromagnetic component 5. The electromagnetic component 5 is mounted in the slot 18 via a snap-fit ​​engagement between the fourth groove 19 and the protrusion 7. This detachable connection allows for winding the coil in a wider space at a higher speed, freeing it from the space constraints of the outer shell. This also results in higher coil winding efficiency.

[0021] The first baffle 8 extends from both ends of the slot 18, and each end has a third groove 14. A wedge 12 is inserted into the third groove 14, and a threaded hole 15 is provided at the bottom of the third groove 14. A bolt 13 passes through the wedge 12 and is screwed into the threaded hole 15. By tightening the bolt 13, the wedge 12 moves towards the bottom of the third groove 14 until it contacts the bottom of the third groove. The wedge 12 expands the third groove 14, and both ends of the first baffle 8 expand and tighten to connect with the slot 18. The first baffle 8 can be firmly fixed in the slot 18.

[0022] The tops of several electromagnetic components 5 enclose a rotor cavity 6, within which the rotor can rotate. The top sides of each electromagnetic component 5 are provided with several serrations, which intersect to form bent channel gaps. Airflow generated by a fan mounted on the motor flows through these channel gaps, creating turbulent flow and resulting in a larger heat transfer coefficient and enhanced heat dissipation. The tops of the electromagnetic components 5 are also provided with several inclined ventilation slots 17, which further improve the heat dissipation effect.

[0023] The motor stator bracket of the present invention significantly improves heat dissipation performance by optimizing the structural design of the second baffle 10, and is suitable for various high-power motors, with broad application prospects in electric vehicles and wind turbines.

[0024] The above embodiments are only for illustrating the technical concept and features of this utility model. Their purpose is to enable those skilled in the art to understand the content of this utility model and implement it. They cannot be used to limit the protection scope of this utility model. All equivalent changes or modifications made in accordance with the spirit and essence of this utility model should be covered within the protection scope of this utility model.
