Description

Technical Field

[0001] This utility model relates to the fields of automatic control technology such as new energy vehicles, industrial automation, aerospace, and robotics, and in particular to a pump motor control component and a lightweight automated device. Background Technology

[0002] In existing permanent magnet motor applications, the motor and controller are typically designed separately. While this design offers some flexibility in certain applications, it also introduces several problems, primarily the following two aspects:

[0003] (1) Energy Loss. Transmission loss due to long-distance cable connections: In a split design, power transmission between the motor and controller requires long cables. These cables inevitably introduce resistance losses, especially under high current conditions, where cable resistance leads to significant energy loss. Electromagnetic Interference (EMI): Long-distance cables are also susceptible to external electromagnetic environments, generating EMI. This not only increases additional energy loss but may also interfere with other electronic devices, affecting the overall system performance.

[0004] (2) Control Delay. Signal transmission delay: The separate structure means there is a physical distance between the motor and the controller, resulting in a time delay in the transmission of signals from the controller to the motor and in the return of feedback signals to the controller. This delay affects the dynamic response speed of the motor, especially in applications requiring rapid response, such as servo systems or robot control. The signal transmission delay prevents the motor from responding to controller commands in a timely manner, thus reducing the overall dynamic performance and control accuracy of the system.

[0005] With the increasing demand from modern industry for efficient, compact, lightweight, highly reliable, and intelligent equipment, traditional discrete designs are no longer sufficient to meet these requirements. Utility Model Content

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0059] It should be noted that, unless otherwise specified, the embodiments and features described in these embodiments can be combined with each other.

[0065] A motor control module is provided on the motor drive control circuit board assembly (20), and the motor control module is electrically connected to the filter module;

[0066] Hall effect components (41) are integrated on the Hall circuit board assembly (40).

[0067] Specifically, the motor (50) is a permanent magnet motor.

[0068] Specifically, both the Hall effect circuit board assembly (40) and the motor drive control circuit board assembly (20) are PCBA (Printed Circuit Board Assembly) assemblies.

[0069] This utility model's integrated design enables rapid replacement through a modular structure, reducing the use of connectors and cables, lowering energy loss, improving overall system efficiency, simplifying assembly processes, reducing labor costs, and minimizing potential failure points. Shortening the signal transmission path and integrating a shielding layer significantly reduces EMI issues and eliminates signal transmission delay. More efficient heat dissipation is achieved by sharing a heat dissipation channel (such as a liquid cooling system) or optimizing the heat conduction path between the motor and control components.

[0070] See Figure 10 The diagram illustrates the working principle of the pump motor control component. The 28V DC power generated is filtered by the filter component and then used to power the motor drive control circuit board component, providing positive and negative signals. The motor drive control circuit board component generates inverted AC power, which is supplied to the stator component of the motor. The rotor component and stator component interact to generate speed and torque. Hall effect sensors (41) detect the rotor's position information and feed it back to the motor control module, thereby helping the motor control module achieve more precise and efficient control of the motor.

[0071] This utility model provides an integrated structural design that installs the motor control components inside a permanent magnet motor, in order to improve the efficiency, compactness, lightweight, and high reliability of the control components.

[0072] See Figure 2Specifically, the mounting surface of the outer casing (10) is set to be square and at least four casing mounting through holes (11) are evenly distributed, and the outer casing (10) and the rear end cover (51) of the motor (50) are fixed through the four casing mounting through holes (11).

To ensure integration and reliability, the filter assembly integrates a shielding housing, a filter circuit, a reverse power-on protection circuit, and an overcurrent protection circuit. The filter circuit, the reverse power-on protection circuit, and the overcurrent protection circuit are installed inside the shielding housing.

[0079] The reverse polarity protection circuit is a protective circuit used in filter components. Its main function is to prevent damage caused by reverse polarity connection of the power supply circuit, and to provide a smooth voltage rise process when the power is turned on to avoid damage to electronic components from instantaneous large current surges.

[0080] Overcurrent protection circuits play a crucial role in filtering components, preventing current from exceeding safe limits and thus protecting electronic equipment from damage.

[0081] Filtering circuits are mainly used to remove noise, spurious signals, and unwanted frequency components from direct current, ensuring the purity of the electrical signal.

[0082] The shielding housing of the filter component is mainly used to prevent external electromagnetic interference (EMI) from affecting the internal circuitry, and also to prevent internally generated electromagnetic interference from affecting other devices or circuits.

[0086] Specifically, the motor drive control circuit board assembly (20) includes a motor drive control circuit board, which is mounted to the top of the filter assembly (30) through the mounting threaded hole inside the first mounting boss (330).

[0087] The height of the first mounting boss (330) needs to be considered in relation to the fixing studs and component safety spacing of the motor drive control circuit board assembly (20), maintaining a certain gap to prevent structural interference and component short circuits. Therefore, setting the first mounting boss (330) provides a clear mounting position for the motor drive control circuit board, ensuring consistent positional accuracy with each installation. The first mounting boss (330) effectively isolates the motor drive control circuit board assembly from other sensitive circuits within the shielded housing, reducing the impact of electromagnetic interference (EMI). Furthermore, the boss provides a fixed mounting reference point for the motor drive control circuit board assembly (20), making the assembly process simpler and faster, reducing the possibility of human error, and facilitating disassembly and maintenance.
