Detailed Description
Exemplary embodiments of the present application will be described in more detail below with reference to the accompanying drawings. While exemplary embodiments of the present application are shown in the drawings, it should be understood that the present application may be embodied in various forms and should not be limited to the embodiments set forth herein. Rather, these embodiments are provided so that this disclosure will be thorough and complete, and will fully convey the scope of the disclosure to those skilled in the art.
With the development of motor technology, motors have gradually evolved from the original devices that were only capable of providing a simple conversion between mechanical and electrical energy to devices that were capable of providing characteristics such as higher torque and that were capable of accommodating more operating scenarios. In general use, in order to realize intelligent control of a motor, a motor controller is usually required to be matched with the motor, so that the operation of the motor can be intelligently controlled through a control algorithm in the motor controller. For example, the motor may be disposed adjacent to the driven object, and the rotation shaft of the motor and the rotation shaft of the driven object may be fixedly connected through, for example, a flange, so that when the motor is rotated by the driving of the controller, the rotation torque of the motor may be transmitted to the rotation shafts of the driven objects fixed together through the flange by means of the flange to drive the rotation shafts of the driven objects to rotate. The controller may be connected to the motor by external connection lines to provide the necessary power and/or control signals to the motor. In general, the controller is provided with a proper placement position due to the fact that the controller contains more precise electrical components, and also needs to provide proper protection for the connection cable between the controller and the motor to prevent damage during operation of the device.
With the appearance of the switched reluctance motor, the dependence degree of the operation of the switched reluctance motor on a motor controller is improved, so that the complexity of the motor can be reduced, and on the other hand, higher requirements are also put on the arrangement of the motor and the corresponding motor controller in an application scene. For example, in the case of separately arranging the motor and the driver thereof as described above, two independent and suitable installation spaces are required to be considered, respectively, and also the path of passage of cables between the two spaces is required to be considered, and particularly as the requirements for functions of the working equipment in the living and working scenes of people become increasingly complicated, more equipment and devices are required to be arranged in a limited space, and thus, higher requirements are also put on the size of a single device, while the scheme of separately arranging the motor and the controller thereof in the prior art encounters great difficulty in achieving the reduction of the occupied space, and in addition, in the trend of increasingly tense installation space inside the equipment, the requisite cable connection between the motor and the controller thereof is also easily damaged during the actual operation of the equipment, thereby causing the motor to malfunction, and in serious cases even causing the damage of the motor or the controller.
Therefore, the embodiment of the application provides a switch reluctance all-in-one machine, which is characterized in that a switch reluctance motor and a controller are contained in different cavities in a shell of the all-in-one machine, and a cable in the prior art is replaced by a connecting terminal arranged on a cavity spacer, so that not only is a smaller occupied space realized, but also the problems of safety risk and the like caused by the external cable in the prior art are solved.
Specifically, as shown in fig. 1, fig. 1 is a schematic diagram showing the structure of a switched reluctance all-in-one machine according to an embodiment of the present application. In the structure shown in fig. 1, the switched reluctance all-in-one machine may include: a housing 1, a switched reluctance motor 2 and a controller 3. The case 1 may include a case, a first side cover, and a second side cover. For example, the housing may extend from a side of the switched reluctance motor 2 opposite to the controller 3 to a side of the controller 3 opposite to the switched reluctance motor 2 in a direction parallel to the rotation axis of the switched reluctance motor 2 to surround the switched reluctance motor 2 and the circumferential side of the controller 3 while extending. The first side cover may be disposed at a side of the switched reluctance motor 2 opposite to the controller 3, for example, may be perpendicular to an edge of the case of the side to form an enclosed space with the case edge, enclosing the switched reluctance motor 2 in the space. The second side cover may be provided at a side of the controller 3 opposite to the switched reluctance motor 2, and may be, for example, perpendicular to an edge of the case of the side to form an enclosed space with the edge of the case, enclosing the controller 3 in the space.
In the present embodiment, the case 1 may form one closed inner space by the housing, the first side cover, and the second side cover, so that the switched reluctance motor 2 and the controller 3 are accommodated therein, for example, the motor chamber 11 may be formed in the case 1 by the first side cover, the housing, and the chamber spacer 13, so that the switched reluctance motor 2 is accommodated therein, and the controller chamber 12 may also be formed by the second side cover, the housing, and the chamber spacer 13, so that the controller 3 may be accommodated therein. Thus, the switched reluctance motor 2 may be fixed, for example, to a corresponding portion of the motor chamber 11 of the housing, while the controller 3 may be fixed, for example, to a corresponding portion of the controller chamber 12 of the housing. Further, the chamber spacer 13 may be fixed to the housing perpendicularly to the housing at both ends in a direction perpendicular to the housing, and the switched reluctance motor 2 and/or the controller 3 may also be fixed to the chamber spacer 13 by fixing members, so that fixing in two directions perpendicular to each other is possible, enhancing fixing firmness of the switched reluctance motor 2 and the controller 3 in the housing 1.
Further, the chamber spacer 13 may include a first connection terminal 131 and a second connection terminal 132. For example, in the own embodiment, the first connection terminal 131 and the second connection terminal 132 may be provided on both sides of the chamber spacer 13, i.e., adjacent to the housings on the different sides, respectively, and may penetrate the chamber spacer 13 in the thickness direction, so that the switched reluctance motor 2 and the controller 3, which are enclosed and fixed in the respective chambers, may be connected by the first connection terminal 131 and the second connection terminal 132, respectively. For example, the first connection terminal 131 may have one end in the motor chamber 11 and the other end in the controller chamber by penetrating the chamber spacer 13, one end in the motor chamber 11 may be connected to a power supply electrode of the switched reluctance motor, and one end in the controller chamber 12 is connected to a high voltage driving board of the controller 3. The high voltage driving board of the controller 3 may be connected to an external power source so that the first connection terminal 131 may transmit power supplied from the external power source received by the high voltage driving board of the controller to the switched reluctance motor 2 instead of a power cable used in the related art. The second connection terminal 132 has one end inside the motor chamber 11 by penetrating the chamber spacer 13 and the other end inside the controller chamber 12, for example, one end inside the motor chamber 11 may be connected to the switched reluctance motor 2 to receive a sensing signal such as a motor temperature signal, a rotation speed signal, a rotation direction signal, etc. from the switched reluctance motor, and may also transmit a control signal such as a control signal generated by the controller 3 or a control signal received from the outside by the controller 3, etc. to the switched reluctance motor 2, and thus, the other end of the second connection terminal 132 inside the controller chamber 12 may be connected to a control circuit board of the controller so as to receive the above control signal from the control circuit board.
The control circuit board in the controller 3 may be arranged parallel to the high voltage drive board and on the opposite side of the high voltage drive board from the switched reluctance motor. In other words, the high-voltage driving board may be located at a side of the controller 3 adjacent to the chamber spacer 13, and the control circuit board may be located at a side of the controller 3 adjacent to the second side cover. A shield support plate may be further provided at a side of the control circuit board adjacent to the high voltage driving board. The shield support plate may be provided with at least one support extending perpendicular to the shield support plate toward the control circuit board. Thus, the control circuit board can be fixed to one side of the high-voltage drive board by means of the support member. In the embodiment of the present application, the number of the supporting pieces may be plural, and may be provided at one side of the high-voltage driving board near the outer shell of the housing 1, so that the fixing strength of the control circuit board can be improved. The first connection terminal 131 may be provided to penetrate the chamber spacer 13 at a side of the chamber spacer 13 adjacent to the outer case of the housing 1, and thus may be fixedly connected to the side of the high voltage driving board, and an external connection terminal 31 for connection with an external, e.g., power cable, may be provided at a side of the high voltage driving board opposite to the side, i.e., a side of the outer case adjacent to the other side opposite to the outer case of the side. The second connection terminal 132 may be connected to the control circuit board at one end within the controller chamber 12 through a first communication through the shield support plate.
In addition, explosion-proof threads may be further provided on the outer wall surfaces of the first and second connection terminals 131 and 132 so that the integrated machine according to the present application may meet explosion-proof requirements. For example, the depth and length of the threads on the outer wall surfaces of the first connection terminal 131 and the second connection terminal 132 may be set according to the environment in which the switched reluctance machine according to the embodiment of the present application is actually applied, so as to meet the explosion-proof requirement of the environment.
The switched reluctance motor 2 may include a motor body 21 and a housing 22. The motor body 21 may be provided on an outer circumferential surface thereof on a side facing the controller 3 with winding connection terminals connected to respective ones of the three-phase stator windings, and the second connection terminals 132 may include a plurality of second connection sub-terminals respectively corresponding to the respective winding connection terminals of the motor body 21, each of which may be electrically connected to its corresponding winding connection terminal in the motor chamber 11, respectively, and connected to a control circuit board in the controller chamber 12 to transmit control signals received from the control circuit board of the controller 3, for example, to the corresponding winding connection terminal to control a rotational speed and a rotational direction of the motor body 21. In the embodiment of the present application, the second connection terminal 132 may not be provided with the second connection sub-terminal corresponding to each winding connection end, and each winding connection end may be connected to the second connection terminal 132, so that the number of terminals provided on the chamber spacer 13 may be reduced, and the durability of the apparatus may be improved. The motor body 21 may be further provided with a first signal terminal 211 on an outer peripheral surface thereof on a side facing the controller 3. The first signal terminal may be connected to a rotational signal output end of the motor 2, which may be an output end outputting a signal indicating a current rotational direction of the motor body 21 of the motor 2, and a side of the housing 22 facing the chamber spacer 13 is provided with the second signal terminal 221. The second signal terminal may be connected to a temperature signal output of the motor 2 to obtain the temperature of the motor when it is in operation.
In particular, in the embodiment of the present application, a cooling passage and an inlet and an outlet of the cooling liquid may be further provided in the casing 22, so that the cooling liquid may flow from the inlet into the cooling passage of the casing 22, the cooling passage may surround the inside of the motor 2, in particular, the motor body 21, so that the temperature at the time of operation of the motor 2 may be reduced by circulating the cooling liquid in the cooling passage thus surrounding the inside of the motor 2, and the cooling liquid circulating in the cooling passage inside the motor 2 may flow out from the outlet due to heat exchange with the motor body 21 due to a temperature rise, and the outlet may be further connected to an external cooling mechanism through a pipe to cool the cooling liquid flowing out from the outlet, and the cooled cooling liquid may be recirculated into the cooling passage through the inlet. Therefore, the circulation speed of the coolant and the cooling target temperature of the external cooling mechanism are adjusted by collecting the temperature of the motor 2 during operation through the second signal terminal, so that the motor 2 can be kept at a proper operating temperature during operation without causing motor failure due to excessive temperature.
In the present embodiment, the other ends of the first and second signal terminals, that is, the other end toward the chamber spacer 13, may be connected to one end of the second connection terminal 132 within the motor chamber 11. So that the rotation state information of the motor received by the first signal terminal, such as information of the rotation speed and the rotation direction, and the operation temperature information of the motor received by the second new terminal, can be transmitted to the control circuit board of the controller 3 through the second connection terminal 132, and the control circuit board can generate rotation control signals according to the collected rotation information, and transmit to the first signal terminal through the second connection terminal 132, and further to each winding connection terminal to which the first signal terminal is connected, to control the rotation state of the motor.
Further, in the embodiment of the present application, the second connection terminal 132 may have a screw extending at least into the controller chamber 12 at a central position thereof, and the screw may extend in a thickness direction of the high-voltage driving plate of the controller 3 and pass through an opening corresponding to the screw in the high-voltage driving plate so that the screw may pass through the high-voltage driving plate through the opening. In addition, the second connection terminal 132 may further include a first screw fixing member and a second screw fixing member for fixing screws passing through the high voltage driving plate. For example, a first screw fixing member may be located at a side of the high-voltage driving plate facing the chamber spacer 13, and a second screw fixing member may be located at a side of the high-voltage driving plate opposite to the chamber spacer to clamp the high-voltage driving plate and firmly fix the screw to the high-voltage driving plate by fixing the screw passing through an opening hole in the high-voltage driving plate from both sides of the high-voltage driving plate.
In addition, the second connection terminal 132 may further include a terminal housing surrounding the screw, the terminal sleeve may extend parallel to the screw to have one end extending into the motor chamber 11 and at least a portion extending into the controller chamber 12 and covering at least a portion of the screw extending from the outer surface of the chamber spacer 13 on the controller chamber 12 side into the controller chamber 12. Thus, the power cable connected to the motor 2 may be connected to, for example, the above-mentioned screw or other electrical connection in the terminal housing by means of the end of the terminal housing located in the motor chamber 11, while the terminal housing, by accommodating the power cable in the motor chamber 11 and extending along the screw into the controller chamber 12, ensures insulation and isolation of the screw or other electrical connection connected to the power cable from the chamber spacer 13, on the one hand, ensuring possible electrical contact of the power cable with the chamber spacer 13 and, on the other hand, also improving the safety against the power cable and the screw or other electrical connection, avoiding damage from external foreign bodies.
Therefore, according to the switched reluctance machine of the embodiment of the present application, the switched reluctance motor and the controller may be previously installed in the motor chamber 11 and the controller chamber 12, respectively, at the time of shipment, and the first connection terminal 131 on the motor may be previously connected to the power interface on the motor. The end of the first connection terminal 131 in the motor chamber 11 may be connected to a power interface on the motor, for example, using a power cable, and the end of the power cable connected to the first connection terminal 131 may be inserted into a terminal housing, so that the power cable may be protected by the terminal housing. Particularly, the problem that the power cable between the motor and the controller is easy to damage due to the fact that the motor is separately placed from the controller in the prior art is avoided, and certain energy loss is not necessarily generated due to the fact that the power cable is long, which is particularly remarkable in the new energy power vehicle scene.
In addition, according to the switched reluctance all-in-one machine of the embodiment of the application, the first signal terminal and the second signal terminal on the motor 2 can be connected to the second connecting terminal 132 when leaving the factory, and signals transmitted by the first signal terminal and the second signal terminal can be debugged, so that when the switched reluctance all-in-one machine of the embodiment of the application is installed in an actual use scene, the debugging of signals can be omitted on site, the efficiency of site installation is improved, and the fault of signal line connection between the motor and the controller due to the complexity of the environment of an application site is avoided. In particular, since the integrated machine according to the embodiment of the application connects the first signal terminal and the second signal terminal to the second connection terminal 132 before leaving the factory, so as to complete the construction of the signal transmission channel between the motor and the controller, the plugging error which may occur when the plurality of signal wires between the motor and the controller are required to be connected respectively in the field in the prior art is avoided, and the reliability of the motor in actual use is greatly improved.
In addition, the outer circumferences of the first connecting terminal 131 and the second connecting terminal 132 can be provided with explosion-proof threads, so that the explosion-proof performance of the integrated machine is greatly improved, and the integrated machine according to the embodiment of the application can be widely applied to scenes such as mines and the like which have requirements on the explosion-proof performance.
According to the switch reluctance integrated machine provided by the embodiment of the application, the motor chamber accommodating the switch reluctance motor and the controller chamber accommodating the controller are respectively arranged in the shell of the integrated machine, and the first connecting terminal and the second connecting terminal which are arranged on the chamber spacing piece between the motor chamber and the controller chamber and penetrate through the chamber spacing piece in the thickness direction are respectively used for connecting the motor in the motor chamber and the controller in the controller chamber correspondingly, so that the integral structural design of the motor and the corresponding controller can be realized, the protection requirement on connection between the motor and the controller during arrangement can be greatly reduced in an application scene, and the occupied space required by the arrangement of the motor and the controller can be greatly reduced.
