[0041] To enable those skilled in the art to better understand the technical solutions in the embodiments of this application, the technical solutions in the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art should fall within the protection scope of the embodiments of this application.

[0042] Figure 1 This is a schematic diagram of a motor end cover according to one embodiment of this application. Figure 2 This is a schematic diagram of the motor end cover of one embodiment of this application from another angle, as shown. Figure 1-2As shown, the motor end cover 100 includes a connecting portion 101, an end portion 102, and a plurality of support ribs 103. The connecting portion 101 is a cylindrical structure, and the end portion 102 is a circular flat plate structure. One end of the connecting portion 101 is connected to a first side surface of the end portion 102, and the second side surface of the end portion 102 is a plane. The plurality of support ribs 103 are arranged radially along the first side surface of the end portion 102. The second end of the connecting portion 101 is provided with a stop for mating with the motor base. The end portion 102 is provided with a mounting hole for mounting a control device. The axis of the mounting hole does not intersect with the support rib 103, or the mounting hole passes through a support rib 103 whose width is greater than the diameter of the mounting hole.

[0043] The control device needs to be installed on the motor end cover 100 on the motor base. Depending on the model of the control device, mounting holes need to be drilled at different positions on the end 102. If the mounting hole partially intersects with the support rib 103 but not the support rib 103, uneven drilling thickness during the drilling process may cause the mounting hole to tilt or damage the drilling equipment. The effectiveness of installing the control device will also be correspondingly reduced if the mounting hole is tilted. Therefore, setting the axis of the mounting hole to not intersect with the support rib 103, or having the mounting hole pass through a support rib 103 with a width greater than the diameter of the mounting hole, ensures consistent drilling thickness during the drilling process. To accommodate different control devices, the position and width of at least some of the support ribs 103 can be adjusted according to the position of the control device mounting hole, as long as the position of the mounting hole meets the above constraints. Specifically, the positions of mounting holes for various control devices can be obtained. These control devices may include equipment such as brakes, encoders, and super-editing machines. The positions and widths of at least some of the support ribs 103 are adjusted accordingly to ensure that the axes of at least some of the mounting holes do not intersect with the support ribs 103, and that other mounting holes pass through the support ribs 103 whose width is greater than the diameter of the mounting holes.

[0044] In addition, the stop provided at the second end of the connecting part 101 can be a convex stop, and correspondingly, the motor base is provided with a concave stop, so that the connecting part 101 can be accurately installed on the motor base. The stop provided at the second end of the connecting part 101 can also be a concave stop, in which case the corresponding position on the motor base is provided with a convex stop.

[0045] Specifically, a boss 104 is provided on the first side of end 102, and the axis of the boss 104 coincides with the axis of end 102; a shaft hole is provided on the boss 104 and end 102, the shaft hole passing through the boss 104 and end 102, and the axis of the shaft hole coincides with the axis of the boss 104. The shaft hole is used to allow the motor shaft to pass through end 102. By providing the boss 104, a certain buffering effect can be provided during the installation of the motor end cover 100 onto the motor frame, thereby protecting the corresponding equipment.

[0046] Specifically, one end of the support rib 103 is connected to the boss 104, and at least a portion of the support ribs 103 have their second ends connected to the inner wall of the connecting portion 101. By connecting one end of the support rib 103 to the boss 104, one end of the support rib 103 can fit against the outer surface of the boss 104, thereby making the motor shaft face the inner surface of the boss 104. Since the inner surface of the boss 104 is a flat surface, damage to the motor shaft is avoided during installation or use.

[0047] Specifically, the outer wall of the connecting part 101 is provided with multiple fixing claws 107, and the fixing claws 107 are provided with bolt holes 1071. The fixing claws 107 are used to connect to the motor frame by bolts passing through the bolt holes 1071 after the stop is mated with the motor frame. After the stop is mated with the motor frame, the position of the motor end cover 100 is relatively fixed with the position of the motor frame. At this time, the bolts are passed through the bolt holes 1071 and installed on the motor frame, which enables the installation of the motor end cover 100.

[0048] In this embodiment, by ensuring that the axis of the mounting hole for installing the control device does not intersect with the support rib 103, or by allowing the mounting hole to pass through the support rib 103 whose width is greater than the diameter of the mounting hole, tilting or damage to the drilling equipment can be prevented when different control devices are installed on the motor end cover 100. Furthermore, existing end covers have heat dissipation ribs and other devices on their second side. When a certain type of control device needs to be installed, the position of the device on the second side is adjusted to make room for that type of control device, which may not be compatible with other types of control devices. By making the second side of the end 102 a plane, the installation of different types of control devices can be supported.

[0049] Figure 3 This is a cross-sectional view of a motor end cover according to an embodiment of this application, as shown below. Figure 1-3As shown, the shaft hole includes multiple hole segments 105 whose diameters decrease sequentially along a direction from the first side of the end 102 to the second side. At least one of the hole segments 105 has an oil seal groove 106 on its inner wall. The oil seal groove 106 is used to accommodate an oil seal. For example, the shaft hole may include four hole segments with diameters of 20cm, 16cm, 10cm, and 6cm respectively. The oil seal groove 106 can be provided in one or more of the four hole segments. By providing the oil seal groove 106 in a direction from the first side of the end 102 to the second side, the flatness of the second side can be ensured, while simultaneously accommodating the oil seal and protecting the motor shaft.

[0050] Figure 4 This is a schematic diagram of a motor end cover according to another embodiment of this application, as shown below. Figure 4 As shown, the plurality of support ribs 103 include a plurality of main support ribs 1031 and at least one auxiliary support rib 1032. The number of main support ribs 1031 is equal to the number of fixing claws 107, and different main support ribs 1031 correspond to different fixing claws 107. The axis of the main support rib 1031 intersects the axis of the bolt hole 1071 on the corresponding fixing claw 107. The auxiliary support rib 1032 is disposed between any two adjacent main support ribs 1031, and the width of the auxiliary support rib 1032 is less than or equal to the width of the main support rib 1031.

[0051] The main support rib 1031, whose axis intersects with the axis of the bolt hole 1071, serves as the main support. Since the position of the main support rib 1031 cannot be changed, if there is a position where the mounting hole intersects with the main support rib 1031, the width of the main support rib 1031 is appropriately widened to ensure that the mounting hole completely passes through the main support rib 1031. Therefore, the width of the main support rib 1031 may be greater than that of the auxiliary support rib 1032. If there is a position where the mounting hole intersects with the auxiliary support rib 1032, the position of the auxiliary support rib 1032 is adjusted accordingly to avoid the mounting hole. Therefore, the width of the auxiliary support rib 1032 is less than or equal to that of the main support rib 1031, but the weight of the auxiliary support rib 1032 can be appropriately reduced, thereby reducing the weight and production cost of the motor end cover 100.

[0052] Specifically, at least one main support rib 1031 is connected to an adjacent auxiliary support rib 1032 via a support portion 110, and the support portion 110 is in contact with the first side of the end portion 102. The mounting hole includes a first mounting hole 111, which is a blind hole provided on the second side of the end portion 102, and the bottom of the first mounting hole 111 is located inside the support portion 110.

[0053] The mounting holes of some control devices may partially coincide with the main support rib 1031. If the main support rib 1031 is widened further, it may cause the main support rib 1031 to become overweight, thereby affecting the balance and weight of the motor end cover 100. Therefore, a support part 110 can be provided between the main support rib 1031 and an adjacent auxiliary support rib 1032, so that the first mounting hole 111 partially passes through the support part 110 to realize the installation of the control device.

[0054] The mounting hole may also include a second mounting hole 112, the axis of which does not intersect with the support rib 103 and passes through the end 102. The mounting hole may also include a third mounting hole 113, the third mounting hole 113 passing through the support rib 103 whose width is greater than the diameter of the third mounting hole 113.

[0055] Specifically, the thickness of the support portion 110 is greater than the thickness of the multiple support ribs 103.

[0056] Since the mounting holes partially pass through the support portion 110, and some mounting holes may need to pass through the support ribs 103, it is known that the length of the connector is at least greater than the sum of the thickness of the support ribs 103 and the thickness of the end portion 102. Therefore, the thickness of the support portion 110 needs to be greater than the thickness of multiple support ribs 103 to ensure that the mounting holes do not pass through the support portion 110.

[0057] Specifically, the connecting part 101, the end part 102, the supporting rib 103, the fixing claw 107, and the supporting part 110 are integrally formed. Integral forming can improve the structural strength of the motor end cover 100.

[0058] Figure 5 This is a schematic diagram of a motor end cover according to another embodiment of this application, as shown below. Figure 5 As shown, the motor end cover 100 also includes a sensor mounting component 108 and a wiring fastener 109. The sensor mounting component 108 and the wiring fastener 109 are disposed on a first side of the end portion 102. The wiring fastener 109 has a first through hole, and the end portion 102 has a second through hole at a position corresponding to the first through hole. The sensor mounting component 108 is used to mount the sensor on the end portion 102. The wiring fastener 109 is used to fix a transmission line passing through the first and second through holes. The transmission line is used to connect the sensor to an external device.

[0059] The sensor can be a temperature sensor, vibration sensor, or other sensor. The sensor is mounted on the sensor mounting bracket 108. The sensor's transmission line, such as a communication line or power supply line, passes through the first through hole and the second through hole in sequence to connect with external devices, such as a power supply or switch.

[0060] In this embodiment of the application, by setting the sensor mounting part 108 and the wiring fixing part 109, a corresponding sensor can be set on the first side of the end 120 to monitor the motor status, thereby improving the safety of the motor.

[0061] Figure 6 This is a front view of a motor according to an embodiment of this application. Figure 7 This is a side view of a motor according to an embodiment of this application, as shown. Figure 6-7 As shown, the motor 200 includes a motor end cover 100, a motor base 201 and a rotor 202 as in any of the first aspects of the embodiments. The motor end cover 100 is mounted on the motor base 201, the shaft of the rotor 202 passes through the motor end cover 100, and the motor base 201 is sleeved on the rotor 202.

[0062] The rotor 202's shaft is the motor shaft described above. The specific implementation of the motor end cover 100 in the motor 200 can be found in the corresponding description in the aforementioned motor end cover embodiments, and will not be repeated here. Those skilled in the art will clearly understand that, for the sake of convenience and brevity, the specific structure and function of the motor end cover 100 described above can be referred to the corresponding description in the aforementioned motor end cover embodiments, and will not be repeated here.

[0063] A third aspect of this application provides a drive and control device 300, including a motor 200 as described in the second aspect of the embodiment and a control device, wherein the control device is mounted on the motor end cover 100 of the motor 200. As mentioned above, the control device is an encoder 401, a brake 402, or an integrated encoder 403, such as... Figure 8-13 As shown, drive and control devices 300 including encoder 401, drive and control devices 300 including brake 402, and drive and control devices 300 including super-encoder 403 are shown respectively. It can be seen that the motor end cover 100 in the drive and control device 300 can be adapted to the installation of various types of control devices. By using different types of control devices, different operating functions of motor 200 can be realized.

[0064] It should be noted that not all modules in the above structural diagrams are necessary, and some modules can be omitted according to actual needs. The structures described in the above embodiments can be physical structures or logical structures. That is, some modules may be implemented by the same physical entity, or some modules may be implemented by multiple physical entities, or they may be jointly implemented by certain components in multiple independent devices.
