[0002] Electric motors are a very common type of power machinery, used in all aspects of production and life, serving as power equipment for machinery, vehicles, household appliances, ships, and more. Due to the compact and narrow interior space of motors, the controllers used to control the motors are typically located externally, adopting a split design. To ensure heat dissipation, these controllers are typically large. Furthermore, this split design requires separate installation and connection to the motor during on-site installation, making on-site installation complex, time-consuming, and labor-intensive, with extremely low labor efficiency. Summary of the Invention

[0032] The following will be combined with the drawings in the embodiments of this application to clearly and completely describe the technical solutions in the embodiments of this application. Obviously, the embodiments described are only part of the embodiments of this application, not all of the embodiments. Based on the embodiments in this application, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of this application.

[0033] Example

[0034] Figure 1 This is a schematic diagram of an exploded view of an integrated motor provided in this embodiment.

[0035] like Figure 1 As shown, the integrated motor provided in this embodiment includes a motor body 100 and an extension housing 200. The extension housing is disposed at the rear end of the motor body. The rear end refers to the end of the motor body opposite the end where the power output shaft is located. The two have the same cross-sectional appearance, so the extension housing can be considered an axial extension of the motor body.

[0036] The controller is located within the extended housing and is configured to receive control commands from the outside and output power to the stator coils within the motor body according to the control commands, thereby driving the motor body. The controller includes a control component 10 and at least one power component 20.

[0037] The motor body is equipped with an internal end cap 101, which isolates the motor's electrical components from the controller and provides mechanical support for the motor's rotor and position sensor. A collector plate 102 is located between the internal end cap and the stator coils. The stator coils within the motor body are connected to the collector plate, where they are then combined to a first AC terminal (not shown). The internal end cap has corresponding holes for connecting the first AC terminal to the controller's second AC terminal (not shown). The second AC terminal consists of three AC conductive posts. The first and second AC terminals are connected by a flexible connection. This connection method reduces overall cost and power loss by 7%, as it eliminates cable harnesses.

[0038] In addition, a heat insulating pad (not shown) is provided between the controller and the internal end cover to prevent the high temperature generated inside the motor body from causing damage to the controller.

[0039] As can be seen from the above technical solution, this embodiment provides an integrated motor, which includes a motor body, a controller, and an extension housing. The cross-sectional shape of the extension housing is the same as the cross-sectional shape of the tail end of the motor body, and is arranged on the tail end so that the extension housing constitutes a natural extension of the motor body; the controller is arranged in the extension housing and is electrically connected to the electrical components of the motor body, and is used to receive external power and control signals, and use the external power and drive the motor body according to the control signals. Because the controller is arranged in the extension housing that naturally extends from the motor body, it forms an organic whole with the motor body, and no layout, wiring, etc. are required during installation, which can effectively solve the complex on-site installation problem of split motors.

[0040] The extension housing of the present application may be a liquid-cooled extension housing 210 cooled by liquid cooling, such as Figure 2 As shown, the liquid-cooled extension housing is provided with a second liquid flow channel 211 that matches the first liquid flow channel in the motor body. The two channels are connected, allowing the motor body and controller to be cooled using a single liquid cooling system. To prevent leakage between the first and second liquid flow channels, a sealing ring is provided between the motor body and the extension housing.

[0041] The extension housing of the present application can also adopt an air-cooled extension housing 220, such as Figure 3 As shown, the air-cooled extension housing is provided with tooth-shaped heat dissipation ribs 221 on the outside, which is conducive to heat dissipation to the air by increasing the heat dissipation area. A sealant is applied between the motor body and the extension housing to prevent water from entering between the extension housings.

[0042] The extended housing in this application includes a hexagonal interior cavity, which houses a hexagonal controller. The controller specifically includes a circular control component and a hexagonal power component. The power component is supported at six points within the hexagonal interior cavity, with a support point 212 located at the intersection of every two sides.

[0043] The control component includes a circuit board and a single chip microcomputer, a driving circuit, a signal acquisition circuit and a plurality of sensors arranged on the circuit board.

[0044] The power assembly includes a multi-layer thick copper circuit board 21 and a plurality of power devices 22 arranged on the multi-layer thick circuit board, such as semiconductor power switches, capacitors, AC conductive columns and DC conductive columns, etc., and also includes a capacitor bracket 23 arranged close to the multi-layer thick copper circuit board. The capacitor bracket is a porous structure with a plurality of holes 231 arranged on it, such as Figure 4 As shown, the holes are used to accommodate corresponding power devices. Each side of the hexagon secures a set of semiconductor power switches, dissipating the generated heat evenly outside the extended housing. After the power devices are housed in the holes, thermally conductive adhesive is filled between the inner wall of the holes and the power devices.

[0045] The power module's multilayer thick copper circuit provides a conductive path for the power devices. Spring clips support the capacitor bracket and the multilayer thick copper circuit board, and an interference fit is employed between the outer edge of the capacitor bracket and the inner edge of the extended housing. The DC terminals within the power module and the DC lead wires are crimped, while the DC lead wires and the controller's end caps are crimped to meet IP68 protection. Conventional connectors are used for signal cables.

[0046] In addition, according to the requirements of power output capacity, multiple power components can be stacked. When multiple power components are used, they can be fixed and connected using a stepped shaft + bolts.

[0047] The various embodiments in this specification are described in a progressive manner, and each embodiment focuses on the differences from other embodiments. The same or similar parts between the various embodiments can be referenced to each other.

Therefore, the appended claims are intended to be interpreted as including the preferred embodiments and all changes and modifications that fall within the scope of the embodiments of the present invention.
