Contents of the invention

The present invention provides a working method of a motor to solve the above problems.

The electric motor provided in the present invention includes a casing, an oil guide plate and a power source, the power source includes a stator and a rotor corresponding to the stator, the stator is fixedly arranged in the casing, and the rotor is rotatably arranged in the Inside the casing, the casing is also provided with an oil inlet and an oil outlet, the oil inlet is set on one side of the rotor, the oil outlet is set on the other side of the rotor, and the oil guide The plate is fixedly arranged on the rotating shaft of the rotor, the oil guide plate is arranged between the stator and the oil inlet, the oil guide plate is provided with an oil guide port, and the oil guide port is provided with an inclined of the leaves.

The rotor can rotate around the axis of the shaft through the rotating shaft in the casing, and cooperate with the stator. After the motor is energized, under the action of the magnetic field force, the rotor rotates, and at the same time, the cooling oil filled in the casing is driven by the thrust generated by the rotation of the oil guide plate. The bottom also starts to flow, the cooling oil enters the casing from the oil inlet, and under the action of the inclined blades on the oil guide plate, the oil guide plate generates thrust, and the cooling oil is sucked by the oil guide plate from the side of the oil inlet, and Compression flows to the side of the oil outlet, and the cooling oil is driven by the oil guide plate, flows through the gap between the rotor and the stator, and finally flows out through the oil outlet on the casing. The setting of the oil guide port on the oil guide plate realizes the flow and discharge of cooling oil in the casing by utilizing the thrust generated by the rotation of the inclined blades. During the flow of the cooling oil, it absorbs the electric heat generated by the motor due to the current, and discharges it through the oil outlet with the cooling oil, taking away the heat from the rotor and stator to cool the motor, because the heat transfer coefficient of the liquid needs to be It is higher than the air, so the cooling oil is used for cooling, the cooling speed is faster, and the cooling efficiency is higher. At the same time, the use of cooling oil as the cooling medium can prevent the motor from sparking under the condition of static electricity and high frequency (flashing phenomenon: in When the stator coil is cut by the permanent magnet magnetic field line of the rotor, high voltage electricity will appear under the induced current, and the high voltage electricity will be discharged in the air medium).

The return flow threshold of one set of return flow rings is limited, and the return flow threshold of the two return flow rings is effectively increased. At low speed and idle speed, the pressure is relatively small. It is not enough to push the backflow ring back, and at high speed, when the pressure rises, when the pressure exceeds the threshold value of the backflow ring, the backflow ring will be pushed open to balance the pressure in the overall shell.

Further, there are at least two power sources, and the at least two power sources are arranged adjacently and side by side in the housing. The two power sources set up in this way can group a plurality of power sources through the control system, and control the power sources of different groups separately, so that the output of different horsepower can be realized to adapt to different use requirements.

Detailed ways

The present invention will be described in further detail below through specific implementation examples and in conjunction with the accompanying drawings.

As shown in Figure 1, the motor provided by the first embodiment of the present invention includes a casing 1 and a power source, the power source includes a stator 2, a rotor 3 corresponding to the stator 2, the stator 2 is fixedly arranged in the casing 1, and the stator 2 is attached to the casing 1. Closed inside the casing 1, the rotor 3 is rotatably supported in the casing 1 through the rotating shaft 31. The casing 1 is also provided with an oil inlet 4 and an oil outlet 5.

During this flowing process, the cooling oil absorbs the electric heat generated by the stator 2, carries away the heat in the housing 1, and discharges it through the oil outlet 5, which reduces the temperature in the motor housing 1 and achieves cooling of the motor. Since the heat transfer coefficient of the liquid is much greater than that of the air, cooling the engine with cooling oil can achieve a better cooling effect, and at the same time, it can effectively prevent the motor from sparking when it works under static electricity and high frequency conditions.

As shown in Figures 2-5, the motor provided by the second embodiment of the present invention includes a casing 1 and a power source, the power source includes a stator 2, a rotor 3 corresponding to the stator 2, the stator 2 is fixedly arranged in the casing 1, and the stator 2 Fitted inside the casing 1, the rotor 3 is rotatably supported in the casing 1 by the rotating shaft 31, the casing 1 is also provided with an oil inlet 4 and an oil outlet 5, the oil inlet 4 is set on one side of the rotor 3, and the oil outlet The port 5 is provided on the other side of the rotor 3 .

The rotor 3 is disposed in the center of the casing 1 , and the rotor 3 is rotatably supported in the casing 1 through a rotating shaft 31 , and the stator 2 is fixedly arranged in the casing 1 around the corresponding rotor 3 .

The motor provided in this embodiment also includes an oil guide plate 6 , an oil sealing ring 7 and a return ring 8 . The oil guide plate 6 is fixedly arranged on the rotating shaft 31 of the rotor 3, the oil guide plate 6 is arranged between the stator 2 and the oil inlet 4, the oil guide plate 6 is provided with an oil guide port, and the oil guide port is provided with inclined blades.

There are two oil sealing rings 7, the oil sealing ring 7 is arranged on the inner wall of the casing 1, the oil sealing ring 7 is arranged adjacent to the oil guide plate 6, and the two oil sealing rings 7 are respectively arranged on both sides of the oil guide plate 6, each seal The oil ring 7 is provided with a return ring 8, the return ring 8 is arranged between the oil seal ring 7 and the oil guide plate 6, the edge of one side of the return ring 8 is fixedly connected to the oil seal ring 7, and the other side of the return ring 8 The edge fits the oil deflector plate 6. The return ring 8 arranged on the side close to the rotor 3 is inclined to the rotating shaft 31 , and the return ring 8 arranged on the side away from the rotor 3 is inclined to the casing 1 . A side of each return ring 8 close to the rotor 3 is inclined toward the housing 1 , and a side of the return ring 8 away from the rotor 3 is inclined toward the rotating shaft 31 .

The rotor 3 of the motor of this embodiment can rotate around the axis of the rotating shaft 31 in the casing 1 through the rotating shaft 31, the rotating shaft 31 is rotatably supported in the casing 1, the stator 2 is fixedly installed in the casing 1, the rotor 3 and the stator 2 are The positions are corresponding, the rotor 3 and the stator 2 can carry out electromagnetic induction cooperation, after the stator 2 is energized, the stator 2 generates a magnetic field, the rotor 3 rotates under the action of the magnetic field force of the stator 2, and the cooling oil flows into the casing from the oil inlet 4 1, flows to the oil guide plate 6, the oil guide plate 6 rotates with the rotating shaft 31, the cooling oil is sucked by the oil guide plate 6 from the side close to the oil inlet 4, and compressed to flow to the side of the oil outlet 5, cooling The oil is pushed by the oil guide plate 6, flows through the gap between the rotor 3 and the stator 2, flows to a place near the oil outlet 5, and is discharged through the oil outlet 5.

At the same time, due to the existence of the oil guide plate 6, the oil sealing ring 7 and the return ring 8, the entire motor casing 1 is divided into several chambers, which are respectively a negative pressure chamber, a high pressure chamber and a flat pressure chamber. Port 4 is small, and the amount of cooling oil flowing in is small, so the relative pressure is low. The high-pressure chamber is because when the rotor 3 rotates at medium and high speeds, the gap between the power sources is not enough to allow three-fifths to four-fifths of the cooling oil to flow through, resulting in a backlog of cooling oil in the high-pressure chamber, thus forming However, when the pressure in the high-pressure chamber is too high, the return ring 8 will be flushed away and flow into the negative-pressure chamber, thereby reducing the pressure of the high-pressure chamber until the pressure of the cooling oil cannot push the return ring 8 away. The last one is the flat pressure chamber, where the high-temperature cooling oil flowing out from the high-pressure chamber temporarily stays. Because the oil outlet 5 is relatively large, the cooling oil will not be pressurized in this chamber to form a higher pressure. Among them, in the high-pressure area, the area between the rotor 3 and the oil guide plate 6 is a relatively ultra-high pressure cavity, which is a part of the high-pressure cavity. When the motor rotor 3 rotates at a medium and high speed, the cooling oil cannot quickly pass through the rotor 3 and the oil guide plate 6. The gap between the stators 2 causes a large amount of cooling oil to stay, so that the pressure of the cooling oil here is relatively high.

The oil sealing ring 7 and the return ring 8 arranged on both sides of the oil guide plate 6 form a complete double return system. At low speed and idle speed, the pressure of the cooling oil in the high pressure chamber is not enough to push the two return rings 8 to Backflow, and at high speed, a large amount of cooling oil is retained, and the pressure of the high-pressure chamber continues to rise, especially compared with the pressure of the ultra-high pressure chamber. When the pressure exceeds the threshold value of the return ring 8, the return ring 8 will Being pushed open, part of the cooling oil flows into the low-pressure chamber, reducing part of the high pressure in the high-pressure chamber, and balancing the overall pressure of the cooling oil in the entire casing 1 .
