See the following data for details:
table 1 comparative data of the series motor of the prior art and the brushless motor of the embodiment of the present invention
Moreover, as can be seen from the table, compared with the prior art, the circular saw in the embodiment of the invention improves the output efficiency and the service life of the motor, and reduces the noise.
In order to avoid the influence of overheating of the high power density brushless motor on the service life of the circular saw provided by the embodiment of the invention, the circular saw further comprises a fan 9 arranged on the rotor shaft 2. In the operation process of the high power density brushless motor, the rotor shaft 2 rotates and simultaneously drives the fan 9 to rotate, so that the high power density brushless motor is subjected to heat dissipation operation.
In the present embodiment, the fan 9 is disposed on the side of the rotor core 3 close to the electric saw blade 6; or the fan 9 is arranged on one side of the rotor core 3 far away from the electric saw cutting blade 6; or, the number of the fans 9 is two, one is positioned on one side of the rotor core 3 close to the electric saw blade 6, and the other is positioned on one side of the rotor core 3 far away from the electric saw blade 6. Will not be described in detail herein and are within the scope of protection.
In order to facilitate air flowing, an air inlet and an air outlet may be disposed on the housing 7, so that the external air enters the housing 7 through the air inlet under the action of the fan and is discharged through the air outlet of the housing 7 after passing through the high power density brushless motor.
Furthermore, in order to ensure the heat dissipation of the controller 5, the positions of the air inlet and the air outlet may be adjusted, so that the external air passes through the controller 5 and the high power density brushless motor under the action of the fan 9, so as to dissipate the heat of the controller 5 while dissipating the heat of the high power density brushless motor.
The inner wall of the motor casing 1 is provided with a wind-blocking ring between the fan 9 and the high-power-density brushless motor, and the flow direction of cooling air is controlled by the wind-blocking ring. In an embodiment, the air inlet of the housing 7 is disposed on a side (left side in fig. 2) away from the electric saw blade 6, and the air inlet of the housing 7 is disposed on a side (right side in fig. 2) close to the electric saw blade 6. External cooling air enters from an air inlet of the casing 7 under the action of the fan 9, sequentially passes through the controller and the high-power-density brushless motor, and is exhausted from an air outlet at the right end of the casing 7 through an inner hole of the wind-blocking ring. By arranging the wind blocking ring, the flow direction of cooling wind is ensured.
As shown in fig. 2, since the axis of the rotor shaft 2 is perpendicular to the operation surface of the electric saw blade 6, it is preferable to arrange the rotor shaft 2 coaxially with the driving shaft of the electric saw blade 6. In order to improve the connection stability and the convenient installation of the rotor shaft 2 and the driving shaft of the electric saw cutting blade 6, the rotor shaft 2 and the driving shaft of the electric saw cutting blade 6 are of an integrated structure. The rotor shaft 2 may also be connected to the drive shaft of the electric saw blade 6 by a coupling or the like, which will not be described in detail here.
In the present embodiment, the high power density brushless motor is a hall-free inner rotor high power density brushless motor; the high power density brushless motor further comprises: rotor core 3 outside rotor shaft 2 is located to the cover, sets up in the stator 4 in the rotor core 3 outside, sets up the permanent magnet 8 between stator 4 and rotor core 3. The outer rotor brushless direct current motor can also be used as a high-power-density brushless motor to be applied to the circular saw provided by the embodiment of the invention.
Among them, a permanent magnet material with high magnetism is preferably used as the permanent magnet 8 to improve the power of the high power density brushless motor.
Since temperature is inversely proportional to current density, the effective heat dissipation of the stator 4 determines the power density of the machine. As shown in fig. 3, the stator 4 includes a stator core 41, a plurality of stator enameled wire groups 42 wound around the stator core 41, and a cold air channel 43 disposed in the stator core 41. By providing the cold air passage 43 for air flowing, the temperature of the stator enameled wire set 42 is effectively reduced. Since the current density is further increased, the high power density of the high power density brushless motor in the present embodiment, that is, the power generated per unit volume of the motor is high.
The cold air passage 43 is formed by a gap between two adjacent stator enameled wire groups 42 and a gap between the stator core 41 and the rotor core 3. The stator enameled wire is wound around the stator core 41 to form a stator enameled wire group 42. In the winding process, a gap exists between two adjacent stator enameled wire groups 42 to allow air to flow, and the gap between the two adjacent stator enameled wire groups 42 is communicated with the gap between the stator core 41 and the rotor core 3, so that the air flow is further enhanced, and the cooling effect is improved.
As shown in the following data table, a high power density brushless motor with a stator 4 having a diameter of 55mm to 65mm and a stator height of 50mm is taken as an example:
TABLE 2 comparative data of the prior art with the present invention
Therefore, the output power per unit volume of the high power density brushless motor provided by the embodiment of the invention is larger than that of the high power density brushless motor in the prior art, but the power is larger than that of the high power density brushless motor in the prior art, so that the power generated by the motor per unit volume is higher, and the high power density of the high power density brushless motor provided by the embodiment of the invention is ensured.
The circular saw provided by the embodiment of the invention can be driven by a direct-current low-voltage power supply or a power-frequency alternating current. The power line is connected with an external power frequency alternating current power supply to drive the high-power-density brushless motor to operate.
The high-power density brushless motor is a direct current motor, and the external power frequency alternating current power supply supplies power frequency alternating current. When the circular saw is connected with an external power supply through a power line, the rectifying and filtering device for converting alternating current into direct current needs to be increased or decreased. That is, in the present embodiment, the circular saw further includes a power line for connecting with an external power source and a rectifying and filtering device disposed in the housing 7, wherein the rectifying and filtering device may be directly integrated on the controller 5 or may be separately disposed. The power frequency alternating current supplied by the external power supply is introduced into the circular saw by the power line, and is converted into direct current to be supplied to the high-power-density brushless motor after passing through the rectifying and filtering device. Wherein the rectifying and filtering means comprise a large capacitor. The conventional power frequency alternating current power supply is 220-240V or 110-127V, and the rectifying and filtering device is adjusted to adapt to different power frequency alternating current power supplies, so that the use area of the circular saw provided by the embodiment of the invention is enlarged.
Because the current intensity of the external power frequency alternating current power supply is high, preferably, an insulating sleeve 10 is arranged between the rotor core 3 and the rotor shaft 2.
Preferably, the motor casing 1 provided by the embodiment of the invention is a plastic motor casing, so that the requirement of double insulation of tools is met, and the use safety is further improved.
However, since a power cord is required to be provided, which hinders the operation of the circular saw, in the present embodiment, it is preferable that the power supply device driving the high power density brushless motor is a battery pack. Because the battery pack supplies direct current, the battery pack directly supplies power to the high-power-density brushless motor. The battery package after charging is used for supplying power to high power density brushless motor, has effectively avoided the operation that the annular saw passes through the power cord with external power supply unit and is connected, has also avoided hindering the condition of annular saw operation because of the power cord among the operation process.
Further, the battery pack is disposed in the case 7. The condition that the normal use of the circular saw is influenced due to the fact that the battery pack is arranged outside is effectively avoided.
The battery pack may be disposed outside the casing 7, and the casing 7 is provided with an interface connected to the battery pack. The battery pack is connected with the casing 7 through an interface and is electrically connected with the high-power-density brushless motor.
In order to facilitate the disassembly, assembly and maintenance of the high-power-density brushless motor, the machine shell 7 is detachably connected with the motor shell 1. That is, when the housing 7 and the motor housing 1 are relatively separated, the high power density brushless motor is installed in the motor housing 1, the controller 5 is installed in the housing 7, and after the wire connection between the controller 5 and the high power density brushless motor is completed, the housing 7 and the motor housing 1 are relatively installed. When the high-power density brushless motor needs to be replaced or maintained, the high-power density brushless motor or the controller 5 in the motor can be maintained only by relatively separating the machine shell 7 from the motor shell 1.
As shown in fig. 2, the casing 7 is connected to the motor casing 1 by bonding, welding, clamping or screwing. Only the connection strength between the casing 7 and the motor casing 1 needs to be achieved.
In this embodiment, the electric saw blade 6 is a high-speed steel woodworking saw blade, a cemented carbide woodworking saw blade, or a cemented carbide metal saw blade. Other types may be provided, and are not described herein.
The embodiments in the present description are described in a progressive manner, each embodiment focuses on differences from other embodiments, and the same and similar parts among the embodiments are referred to each other.
The previous description of the disclosed embodiments is provided to enable any person skilled in the art to make or use the present invention.
