Description

Technical Field

[0002] In existing permanent magnet motor applications, the motor and the controller usually adopt a separated design. Although this design has a certain degree of flexibility in some application scenarios, it also brings many problems, mainly including the following two aspects:

[0003] (1) Energy loss. Transmission loss caused by long-distance cable connection. In the separated design, the power transmission between the motor and the controller needs to be connected through a long cable. These cables will inevitably introduce resistance loss. Especially in the case of high current, the resistance of the cable will cause significant energy loss. Electromagnetic interference (EMI). Long-distance cables are also easily affected by the external electromagnetic environment and generate electromagnetic interference, which not only increases additional energy loss but may also interfere with other electronic devices and affect the overall performance of the system.

[0004] (2) Control delay. Signal transmission delay. The separated structure means that there is a physical distance between the motor and the controller, and time delay will occur during the process of the signal being transmitted from the controller to the motor and the feedback signal returning to the controller. This delay will affect the dynamic response speed of the motor, especially in application scenarios that require fast response, such as servo systems or robot control. Affecting the dynamic response speed. Due to the existence of signal transmission delay, the motor cannot respond to the instructions issued by the controller in a timely manner, thus reducing the overall dynamic performance and control accuracy of the system.

[0060] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention.

[0061] It should be noted that, without conflict, the embodiments in the present invention and the features in the embodiments can be combined with each other.

[0062] Next, the present invention will be further described in conjunction with the accompanying drawings and specific embodiments, but it is not a limitation of the present invention.

[0063] Refer to Figure 1 , the present invention provides a motor control component for a pump, including:

[0064] A Hall circuit board assembly (40), a filtering assembly (30), and a motor drive control circuit board assembly (20) are arranged in sequence from bottom to top;

[0065] A housing (10) is fixed on the rear end cover (51) of a motor (50), and the Hall circuit board assembly (40), the filtering assembly (30), and the motor drive control circuit board assembly (20) are inside the housing (10);

[0066] The filtering assembly (30) includes a filtering module for filtering the input direct current;

[0067] A motor control module is arranged on the motor drive control circuit board assembly (20). The motor control module is electrically connected to the filtering module and is used for forming a motor drive signal from the filtered direct current to drive and control the motor (50);

[0068] Hall components (41) are integrated on the Hall circuit board assembly (40), and the Hall components (41) are used for collecting the position information of the rotor of the motor (50).

[0069] Specifically, the motor (50) is a permanent magnet motor.

[0070] Specifically, both the Hall circuit board assembly (40) and the motor drive control circuit board assembly (20) are PCBA (Printed Circuit Board Assembly) assemblies.

[0071] The integrated design of the present invention can be realized by a modular structure for quick replacement, reducing the use of connectors and cables, reducing energy loss, improving the overall system efficiency, simplifying the assembly process, reducing labor costs, and reducing failure points. By shortening the signal transmission path and integrating the shielding layer design, the EMI problem is significantly reduced, and the signal transmission delay is eliminated. By sharing a heat dissipation channel (such as a liquid cooling system) between the motor and the control component or optimizing the heat conduction path, more efficient heat dissipation is achieved.

[0072] See Figure 10 , as the working principle diagram of the pump motor control component. After filtering the generated 28V direct current through the filtering component, it supplies power to the motor drive control circuit board assembly and provides positive and negative signals. The motor drive control circuit board assembly generates an inverted alternating current and supplies it to the stator assembly of the motor. The rotor assembly and the stator assembly of the motor interact to generate speed and torque. The Hall components (41) detect the position information of the rotor and feedback it to the motor control module, so as to help the motor control module achieve more precise and efficient control of the motor.

[0073] The present invention provides an integrated structure design for installing a motor control component inside a permanent magnet motor to meet the requirements of high efficiency, compactness, light weight, and high reliability of the control component.

[0074] See Figure 2 , specifically, the mounting surface of the outer housing (10) is set to be square and evenly distributed with at least four outer housing mounting through holes (11), and the outer housing (10) and the rear end cover (51) of the motor (50) are fixed through the four outer housing mounting through holes (11).

[0076] Furthermore, the filter assembly (30) further includes a shielding housing, the filter module is arranged inside the shielding housing, and the shielding housing includes an upper shielding housing (33) and a lower shielding cover plate (31);

[0079] Specifically, the bottom of the upper shielding housing (33) and the top of the lower shielding cover plate (31) are fixedly connected by countersunk head screws (32).

[0080] The filter assembly (30) is designed to meet the requirements of product electromagnetic compatibility related tests. To ensure integration and reliability, the filter assembly includes an integrated shielding housing, filter circuit, reverse - connection and slow - power - on protection circuit, and over - current protection circuit, etc. The filter circuit, reverse - connection and slow - power - on protection circuit, and over - current protection circuit are installed inside the shielding housing.

[0081] The reverse - connection and slow - power - on protection circuit is a protection circuit used in the filter assembly. Its main function is to prevent damage to the circuit caused by incorrect power supply polarity and provide a smooth voltage rise process when the power supply is turned on to avoid damage to electronic components caused by instantaneous large - current impact.

[0082] The over - current protection circuit plays a crucial role in the filter assembly. It can prevent the current from exceeding the safe range, thereby protecting electronic devices from damage.

[0083] The filter circuit is mainly used to remove noise, clutter, and unwanted frequency components in direct current to ensure the purity of the electrical signal.

[0088] Specifically, the motor drive control circuit board assembly (20) includes a motor drive control circuit board, and the motor drive control circuit board is installed on the top of the filtering component (30) through the installation threaded hole inside the first mounting boss (330).

[0089] The height of the first mounting boss (330) needs to be considered in relation to the fixing studs of the motor drive control circuit board assembly (20) and the safety distance of components, maintaining a certain gap to avoid structural interference and component short - circuit. It can be seen that setting the first mounting boss (330) provides a clear installation position for the motor drive control circuit board, ensuring consistent position accuracy for each installation. The first mounting boss (330) can effectively isolate the motor drive control circuit board assembly from other sensitive circuits inside the shielding housing, reducing the influence of electromagnetic interference (EMI). In addition, the boss provides a fixed installation reference point for the motor drive control circuit board assembly (20), making the assembly process more simple and fast, reducing the possibility of human operation errors, and being easy to disassemble and repair.
