Description

Technical Field

[0001] This utility model relates to the field of motor simulator technology, specifically to a motor simulator host and casing. Background Technology

[0002] The common control logic of a DC motor is as follows: the controller receives the control signal and then outputs voltage / current to control the motor's operation. The motor's output (position / angle / current) is collected by the controller as a negative feedback signal. The controller compares the motor's output with the control signal and then adjusts the output current / voltage to make the motor's output more precise.

[0003] A motor simulator is a device used to simulate the dynamic behavior of a motor, primarily for performance testing of motor-driven frequency converters. Its working principle is based on a precise mathematical model of motor dynamics, using sampled motor port voltage as an input variable, combined with a control system to achieve zero steady-state error tracking of the commanded current. The basic principle of a motor simulator.

[0004] Sampling port voltage: The motor simulator samples its port voltages as input variables for the motor's dynamic mathematical model. This step is to obtain the motor's real-time operating status and ensure the accuracy of the simulation.

[0005] Model-based current calculation: Based on the sampled voltage data, the motor port current is obtained through mathematical model calculation and used as the command current of the inverter current loop.

[0006] Control system tracking: The control system enables zero steady-state error tracking of the command current, ensuring that the simulator can accurately reflect the actual working state of the motor.

[0007] Currently, motor simulator hosts typically house multiple modules. If the modules are too close together, it will affect the overall heat dissipation of the host and make it inconvenient to switch between multiple modules. Therefore, we provide a motor simulator host and its casing. Utility Model Content

[0008] To address the shortcomings of existing technologies, this utility model provides a motor simulator host and housing, which can achieve more efficient host heat dissipation.

[0009] To achieve the above objectives, this utility model is implemented through the following technical solution: a motor simulator host, wherein the motor simulator host is composed of multiple simulation motherboards, and each simulation motherboard is provided with a heat dissipation unit at its bottom;

[0010] The heat dissipation unit includes a heat dissipation bracket detachably connected to the bottom of the simulated motherboard. A heat dissipation fin is snapped onto one side of the heat dissipation bracket, and a heat conduction strip is fixedly connected to the top of the heat dissipation fin. The heat conduction strip extends to the center of the heat dissipation bracket and abuts against the simulated motherboard.

[0011] A cooling fan is provided in the middle of the heat dissipation bracket, and the operation of the cooling fan creates an airflow channel between the heat conduction strip and the heat dissipation fins.

[0012] Optionally, the sidewall of the heat-conducting strip is provided with a positioning plate, and the positioning plate and the heat dissipation bracket are respectively fixedly connected to the simulated motherboard after being inserted with fixing bolts.

[0013] Optionally, the heat dissipation bracket has a hollow internal structure.

[0014] A housing for a motor simulator host includes a cabinet, with doors rotatably connected to both the front and back of the cabinet. The doors have ventilation holes, which are sealed by magnetically attached baffles. The housing also includes:

[0015] The fan assembly is connected to the top of the cabinet for the convergence of airflow inside and outside the cabinet;

[0016] The simulated motherboard mounting assembly is connected to the side wall of the cabinet to simulate the fixed support of the motherboard.

[0017] Optionally, the magnetic baffle is a plate-shaped structure with magnetic strips on the edge, and two magnetic baffles can be stacked and attracted to each other. The door is provided with a lock for fixing the door.

[0018] Optionally, the fan assembly includes a cabinet top frame with two through holes, on which two fan frames are mounted along the through holes, and an exhaust fan is fixedly connected to the inner side wall of the fan frame.

[0019] Optionally, the simulated motherboard mounting assembly includes two vertical frames fixedly connected to the inner side wall of the cabinet. The side wall of the vertical frame has a slot, and a fixed crossbeam is engaged in the slot.

[0020] Optionally, the crossbeam includes a spring fixedly connected to the inner wall of the crossbeam, one end of the spring being fixedly connected to a hook, the hook being slidably installed on the inner wall of the crossbeam, and restricting the crossbeam from sliding up and down relative to the vertical frame when the hook is engaged with the inner wall of the slot.

[0021] This utility model provides a motor simulator host and casing, which has the following beneficial effects:

[0022] The main unit and housing of this motor simulator utilize multiple heat dissipation units. During heat dissipation, heat is first transferred from the heat conduction strips to the heat dissipation fins. The cooling fan then drives airflow to converge, providing air cooling to the heat dissipation fins and heat conduction strips. A certain number of ventilation holes can be opened as needed during heat dissipation. When heat dissipation is not required, magnetic baffles can be placed over the ventilation holes to block them, thereby reducing the risk of dust entering the cabinet. Different numbers of simulation motherboards can be installed according to usage requirements, and the spacing between the simulation motherboards can also be adjusted. Specifically, pressing the hooks compresses the springs, disengaging them from the vertical frame, allowing the crossbeam to slide. After adjustment, the springs automatically extend and engage with the hooks in the slots to fix the crossbeam in place. Attached Figure Description

When the following description relates to the drawings, unless otherwise indicated, the same numerals in different drawings denote the same or similar elements. The embodiments described in the following exemplary embodiments do not represent all embodiments consistent with this disclosure.

All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the scope of protection of the present utility model.

[0033] Please see Figures 1 to 7 The present invention provides a technical solution: a motor simulator host, which is composed of multiple simulation motherboards 10, and each simulation motherboard 10 is provided with a heat dissipation unit 20 at the bottom.

[0034] The heat dissipation unit 20 includes a heat dissipation bracket 21 that is detachably connected to the bottom of the analog motherboard 10. A heat dissipation fin 22 is snapped onto one side of the heat dissipation bracket 21. A heat conduction strip 23 is fixedly connected to the top of the heat dissipation fin 22. The heat conduction strip 23 extends to the center of the heat dissipation bracket 21 and abuts against the analog motherboard 10. The heat dissipation fin 22 is formed by multiple heat conduction plates connected with gaps. The heat conduction strip 23 covers the top of the heat dissipation fin 22.

[0035] A cooling fan 24 is provided in the middle of the heat dissipation bracket 21. When the cooling fan 24 works, an airflow channel is formed between the heat conduction strip 23 and the heat dissipation fins 22. The airflow can converge when passing through the heat conduction strip 23 and the heat dissipation fins 22, thereby achieving the effect of heat dissipation.

[0036] As a preferred embodiment, based on the above method, the side wall of the heat conduction strip 23 is further provided with a positioning piece 25. The positioning piece 25 and the heat dissipation bracket 21 are respectively fixedly connected to the simulation motherboard 10 after the fixing bolts 26 are inserted through them. The heat dissipation bracket 21 has a hollow structure inside. The fixing bolts 26 inserted through the positioning piece 25 and the heat dissipation bracket 21 are fixedly connected to the simulation motherboard 10, which can facilitate the disassembly and maintenance in the later stage.

[0037] A housing for a motor simulator host includes a cabinet 30. The cabinet 30 has doors 31 rotatably connected to both its front and back. Each door 31 has ventilation holes 32. The doors 31 are sealed to the ventilation holes 32 by magnetically attached baffles 33. The magnetic baffles 33 can be removed to open the housing, and can be placed over the ventilation holes 32 to seal them. The housing also includes:

[0038] Fan assembly 40 is connected to the top of cabinet 30 for the convergence of airflow inside and outside cabinet 30;

[0039] The simulated motherboard mounting component 50 is connected to the side wall of the cabinet 30 to provide fixed support for the simulated motherboard 10.

[0040] As a preferred embodiment, based on the above method, the magnetic baffle 33 is a plate-shaped structure with magnetic strips on the edge. Two magnetic baffles 33 can be stacked and attracted together. The door 31 is provided with a door lock for fixing the door 31. The door lock makes it easy to fix the door 31. The operation of the magnetic baffle 33 is convenient.

[0041] As a preferred embodiment, based on the above method, the fan assembly 40 further includes a cabinet top frame 41 with two through holes. Two fan frames 42 are installed on the cabinet top frame 41 along the through holes. An exhaust fan 43 is fixedly connected to the inner side wall of the fan frame 42. When the exhaust fan 43 is working, it can draw out the heat flow inside the cabinet 30, and the airflow on the outside can then enter through the heat dissipation hole 32.

[0042] As a preferred embodiment, based on the above method, the simulated motherboard mounting assembly 50 further includes two vertical frames 51 fixedly connected to the inner side wall of the cabinet 30. The side wall of the vertical frame 51 is provided with a slot 52, and a fixed crossbeam 53 is engaged in the slot 52. The crossbeam 53 includes a spring 54 fixedly connected to the inner side wall of the crossbeam 53. One end of the spring 54 is fixedly connected to a hook 55. The hook 55 is slidably installed on the inner wall of the crossbeam 53. When the hook 55 is engaged in the inner wall of the slot, it restricts the crossbeam 53 from sliding up and down relative to the vertical frame 51.

[0043] In summary, the motor simulator host and housing, during use, dissipate heat through multiple heat dissipation units 20. During heat dissipation, the heat-conducting strips 23 first transfer heat to the heat dissipation fins 22. The cooling fan 24 drives airflow to converge, providing air cooling to the heat dissipation fins 22 and the heat-conducting strips 23. A certain number of heat dissipation holes 32 can be opened according to usage requirements. When heat dissipation is not needed, the magnetic baffle 33 can be placed over the heat dissipation holes 32 to block them, thereby reducing the risk of dust entering the cabinet. Different numbers of simulation motherboards 10 can be installed according to usage requirements, and the spacing between the simulation motherboards 10 can be adjusted. Specifically, pressing the hook 55 compresses the spring 54, disengaging it from the vertical frame 51, allowing the crossbeam 53 to slide. After adjustment, the spring 54 automatically extends to engage with the hook 55, locking it into the slot 52 to fix the crossbeam 53. The simulation motherboards 10 and the crossbeam 53 are fixed together with bolts.
