Description

Technical Field

[0001] The utility model relates to the technical field of brushless motors, in particular to a stator of a brushless motor and a brushless motor. Background Art

[0002] A brushless DC motor consists of a motor main body and a driver, and is a typical mechatronic product. Since the brushless DC motor operates in an automatic control mode, it does not require an additional starting winding on the rotor like a synchronous motor under variable frequency speed regulation during heavy load starting, nor does it generate oscillations and loss of synchronization during load mutation.

[0003] In the existing brushless motor, the copper bars on the stator assembly of the motor only play a role in conducting electricity during operation and cannot play a role in heat dissipation, resulting in a relatively high temperature of the coil when the motor is working. After the temperature rises, the resistance of the winding system becomes larger, thereby reducing the motor efficiency and affecting the overall performance of the motor.

[0004] Therefore, we propose a stator of a brushless motor and a brushless motor. Summary of the Utility Model

[0005] The utility model mainly solves the technical problems existing in the above-mentioned prior art, and provides a stator of a brushless motor and a brushless motor.

[0006] To achieve the above object, the utility model adopts the following technical solutions. A stator of a brushless motor and a brushless motor include a housing. Six iron cores are fixedly installed on the inner wall of the housing. Enameled wires are arranged on each iron core. A circulation component is arranged between every two enameled wires. Each circulation component includes a heat-conducting flat tube. A fourth pipe is integrally formed at the front end of the heat-conducting flat tube. A connecting pipe is fixedly installed at the front end of the fourth pipe. A third pipe is fixedly installed at the top end of the connecting pipe. A heat-dissipating flat tube is integrally formed at the rear end of the third pipe. A second pipe is integrally formed at the rear end of the heat-dissipating flat tube. A circulation pump is fixedly installed at the rear end of the second pipe. A first pipe is integrally formed at the rear end of the heat-conducting flat tube. The rear end of the first pipe is fixedly installed at the drainage end of the bottom end of the circulation pump. Heat-dissipating fins are fixedly sleeved on the outer wall of the housing. Each heat-dissipating flat tube is fixedly inserted into the heat-dissipating fins. A cooling medium is filled in each circulation component.

[0007] Further, a heat-conducting pad is arranged between each heat-conducting flat tube and the enameled wires on both sides. Both sides of each heat-conducting pad are respectively attached to the heat-conducting flat tube and the enameled wire.

[0008] Further, an installation plate is fixedly installed at one end of each heat-conducting flat tube close to the heat-dissipating flat tube. Each installation plate is fixedly installed on the inner wall of the housing.

[0009] Further, a front cover is fixedly installed at the front end of the housing, and each of the fourth pipes is fixedly inserted into the front cover.

[0010] Further, a rear cover is fixedly installed at the rear end of the housing, and each of the first pipes is fixedly inserted into the rear cover.

[0011] Further, a mounting bracket is fixedly installed behind the rear cover, and each of the circulation pumps is fixedly installed on the mounting bracket.

[0012] A brushless motor includes the brushless motor stator described above.

[0013] Beneficial Effects

[0014] The present utility model provides a brushless motor stator and a brushless motor, having the following beneficial effects:

[0015] 1. When the brushless motor stator and the brushless motor are in use, the circulation pump is started, and the cooling medium enters the heat-conducting flat tube through the first pipe. The heat generated during the operation of the enameled wire is transferred to the cooling medium in the heat-conducting flat tube through the heat-conducting pad. The cooling medium after absorbing the heat enters the heat-dissipating flat tube through the fourth pipe along the connecting pipe and the third pipe. The cooling medium in the heat-dissipating flat tube transfers the heat to the heat-dissipating fins with a larger surface area to complete heat dissipation, and finally circulates back to the heat-conducting flat tube through the second pipe and the circulation pump, achieving the effect of circulating heat dissipation, avoiding the situation that the coil temperature is too high during the operation of the motor and causing a large resistance in the winding system, ensuring the stability of the overall performance of the motor, and thus improving the motor efficiency.

[0016] 2. The brushless motor stator and the brushless motor transfer the heat generated during the operation of the enameled wire out of the housing through the set circulation component, and then release it into the air by the heat-dissipating fins, avoiding the situation that the heat accumulates in the housing and causes the winding to melt. At the same time, the relatively stable temperature in the housing can extend the service life of the device.

[0017] 3. The brushless motor stator and the brushless motor integrally form the third pipe and the second pipe at the front and rear ends of the heat-dissipating flat tube, and integrally form the fourth pipe and the first pipe at the front and rear ends of the heat-conducting flat tube, so that the pipeline interface is located outside the housing, ensuring that when liquid leakage occurs at the pipeline interface, it will not damage the internal structure of the housing, effectively improving the safety of the device.

The specific structure of the brushless motor stator refers to the above embodiments. Since the present brushless motor adopts all the technical solutions of all the above embodiments, it also has all the beneficial effects brought by the technical solutions of the above embodiments, which will not be elaborated here one by one.

[0030] The working principle of the present utility model: When the device is in use, the circulation pump 8 is started. The cooling medium enters the heat-conducting flat tube 15 through the first pipe 7. The heat generated during the operation of the enameled wire 17 is transferred to the cooling medium in the heat-conducting flat tube 15 through the heat-conducting pad 16. The cooling medium after absorbing the heat enters the heat-dissipating flat tube 10 through the fourth pipe 13 along the connecting pipe 12 and the third pipe 11. The cooling medium in the heat-dissipating flat tube 10 transfers the heat to the heat-dissipating fins 3 with a larger surface area to complete heat dissipation, and finally circulates back to the heat-conducting flat tube 15 through the second pipe 9 and the circulation pump 8, achieving the effect of circulating heat dissipation, avoiding the situation that the coil temperature is too high during the operation of the motor and causing a large resistance in the winding system, ensuring the stability of the overall performance of the motor, and thus improving the motor efficiency.

[0031] By setting up a circulating component, the heat generated during the operation of the enameled wire 17 is taken away from the inside of the housing 1 and then released into the air by the heat dissipation fins 3, avoiding heat accumulation in the housing 1 and causing the winding to fuse. At the same time, the relatively stable temperature inside the housing 1 can extend the service life of the device.
