Description

Technical Field

[0001] This utility model relates to the field of servo motor testing technology, and in particular to a servo motor simulated loading test device. Background Technology

[0002] The servo motor simulation loading test equipment is a set of equipment that uses a high-precision Siemens servo motor to load a brushless motor and a KISTLER dual-range torque sensor. At the same time, it uses a multi-functional high-precision power analyzer to read the brushless motor's torque, speed, output power, phase current, phase voltage, phase power, input power, voltage, current, input power of the brushless motor controller, motor efficiency, driver efficiency, and overall efficiency.

[0003] It can simultaneously detect various motor characteristics such as: temperature rise test, forward and reverse speed difference, continuous stall, peak stall data, operating range, back EMF constant, torque fluctuation, torque fluctuation coefficient, speed regulation rate test, torque change time, corresponding speed change time, corresponding position tracking error, static friction torque, cogging torque, electrical time constant, thermal resistance and thermal time constant, overload test, inertia adaptation range, T / N curve test, and B-method efficiency curve.

[0004] During the actual operation of the servo motor simulation loading test equipment, a large amount of heat is generated internally due to prolonged high-load operation, causing the temperature of the core components to rise sharply. Although the test device's casing is designed with a heat dissipation vent structure, this passive cooling method has significant limitations. Hot air stagnates within the confined chassis, making it difficult to form effective convection circulation, which exacerbates the heat accumulation problem. This insufficient heat dissipation efficiency is particularly prominent in high-temperature environments during summer or under continuous operation conditions, not only affecting the accuracy of test data but also potentially triggering overheat protection mechanisms and causing test interruptions.

[0005] Even more problematic is that open ventilation holes become the main channels for external contaminants to enter. Fine dust suspended in the air is adsorbed onto the circuit board surface by airflow, while water molecules in humid air condense at metal contacts. Long-term corrosion from these impurities and moisture can trigger a series of chain reactions, such as contact oxidation and decreased insulation performance. In severe cases, it can even cause measurement deviations in precision sensors or malfunctions in control systems. The conductive substances formed by the mixture of oil and dust accumulated inside the testing equipment can also pose a short circuit risk, while the humid environment accelerates the electrochemical corrosion process of metal components. These potential threats are constantly shortening the service life of the testing equipment.

[0006] Chinese patent discloses an ultra-high-speed servo motor testing device (authorization announcement number CN216595421U). The patent technology mainly consists of a base plate, a servo motor on top of the base plate, and a moving structure on top of the base plate. The moving structure includes a curved plate, a vertical rod, a threaded rod, and a vertical cylinder. The bottom of the threaded rod is rotatably connected to the top side of the base plate through a bearing, and the curved plate is threadedly connected to the upper outer wall of the threaded rod.

[0007] However, this patent still has shortcomings. When testing a servo motor using this simulated load testing device, it can cause excessive load and increased internal temperature. While the testing device typically has ventilation holes on both sides, relying on natural heat dissipation through these holes is inefficient and ineffective. Furthermore, it easily allows dust, impurities, and moisture from the air to enter, potentially damaging the testing device. Therefore, those skilled in the art have provided a servo motor simulated load testing device to address the problems mentioned in the background section. Utility Model Content

[0017] Furthermore, a pipe is installed on the other side of the testing device, and four pillars arranged in a rectangular array are fixed on the lower surface of the testing device.

[0018] Specifically, once the pipeline is connected, it facilitates the exhaust of air blown into the testing device, which helps to dissipate heat from the testing device. The four pillars can support the testing device, making the overall device stable.

[0019] Furthermore, a second pipe is installed on one side of the upper end of the outer wall of the spiral heat exchanger tube, a third pipe is installed on one side of the lower end of the outer wall of the spiral heat exchanger tube, an installation hole 1 is opened on one side of the upper end of the outer wall of the circular sleeve 1, an installation hole 2 is opened on one side of the lower end of the outer wall of the circular sleeve 1, the top end of the second pipe passes through the first installation hole and is fixed, and the bottom end of the third pipe passes through the second installation hole and is fixed.

[0027] 2. Beneficial effects

[0028] Compared with existing technologies, the advantages of this utility model are:

[0029] This utility model adds a heat exchange component to the test component. When the test device tests the servo motor and heat dissipation is required, cooling water is introduced into pipe two. The cooling water enters the spiral heat exchange tube and then exits from pipe three for circulation. Air is blown into the through hole one. After heat exchange and cooling through the spiral heat exchange tube, it is blown into the test device for heat dissipation and cooling, thereby improving the heat dissipation effect of the test device.

[0030] Simultaneously, a heat dissipation component is added. When the test device is testing the servo motor, if heat dissipation is required, activated carbon or water-absorbing material is filled between filter screen one and filter screen two as needed. Then, the motor body is started, causing the fan blades to rotate and blowing outside air into the through hole two. The air blown into the through hole two is treated by activated carbon or absorbent material before being blown into the test device for heat dissipation. This achieves the effect of dust removal or dehumidification of the air blown into the test device as needed.

[0031] Of course, any product implementing this utility model does not necessarily need to achieve all of the advantages described above at the same time. Attached Figure Description

[0057] Example 2

[0058] Please see Figures 5-7 As shown, and;

[0059] The heat dissipation component 300 is located on one side of the heat exchange component 200;

[0060] The heat dissipation assembly 300 includes a second round sleeve 330 installed on one side of the first round sleeve 210, a second through hole 331 opened on one side of the second round sleeve 330, a first round disk 380 fixed to the inner wall of the second through hole 331, a threaded disk 390 threadedly connected to the first round disk 380, a round cover 320 installed on one side of the second round sleeve 330, and a fan blade 324 rotatably connected to the round cover 320.

[0061] One side of the round sleeve 210 has an annular screw groove 211, and one side of the round sleeve 330 has a threaded ring 340. The threaded ring 340 extends into the annular screw groove 211 and is threaded. The front and rear ends of the outer wall of the round sleeve 330 are respectively fixed with handles 350.

[0062] A threaded groove 381 is provided on one side of the disc 380. A mounting hole 382 is provided on one side of the inner wall of the threaded groove 381. A filter screen 383 is fixed on the inner wall of the mounting hole 382. The threaded disc 390 extends into the threaded groove 381 and is threadedly connected. A mounting hole 4 391 is provided on one side of the threaded disc 390. A filter screen 2 392 is fixed on the inner wall of the mounting hole 4 391. A handle 393 is fixed at both the front and rear ends of one side of the threaded disc 390.

[0063] The other side of the round sleeve 330 has an annular screw groove 332. The round cover 320 has a threaded ring 370 fixed on one side. The round cover 320 has a round groove 323 on one side. The other side of the round cover 320 has a vent hole 321 and a round hole 322. The motor body 310 is fixed on the other side of the round cover 320. The drive shaft of the motor body 310 extends into the round hole 322. The drive shaft of the motor body 310 is fixed with a fan blade 324 on one side. The threaded ring 370 extends into the annular screw groove 332 and is threaded. The front and rear ends of the round cover 320 are respectively fixed with handles 360.

[0064] The motor body 310 has a drive shaft that fixes the fan blades 324, providing power for the rotation of the fan blades 324, so that air can be blown into the test device 120 for heat dissipation.

[0065] The 310 motor body is a three-phase asynchronous motor, whose structure and working principle are closely related. The motor mainly consists of two parts: the stator and the rotor. The stator is the stationary part, composed of a stator core and stator windings. The stator core is made of laminated silicon steel sheets with slots inside, where the three-phase symmetrical windings are embedded. When three-phase alternating current is applied, a rotating magnetic field is generated. The rotor is the rotating part of the motor, and there are two types: squirrel-cage rotors and wound-rotor rotors. A squirrel-cage rotor consists of a rotor core and embedded conductor bars, resembling a squirrel cage in shape. A wound-rotor has three-phase symmetrical windings wound on the rotor core, connected to an external resistor via slip rings.

[0066] The working principle of an electric motor is based on the interaction between electromagnetic induction and a rotating magnetic field. When three-phase alternating current is applied to the three-phase stator windings, a rotating magnetic field is generated in space. The rotational speed of this rotating magnetic field is called the synchronous speed, which is determined by the power supply frequency and the number of poles of the motor. The rotating magnetic field cuts the rotor bars, inducing electromotive force and current in the rotor. The induced current interacts with the rotating magnetic field to generate an electromagnetic force, thereby forming an electromagnetic torque that drives the rotor to rotate.

[0067] Use of heat dissipation component 300;

[0068] When the testing device 120 tests the servo motor, and heat dissipation is required, threaded ring 340 is inserted into annular groove 211 and threaded, and threaded ring 370 is inserted into annular groove 332 and threaded. Activated carbon or absorbent material is filled between filter screen 392 and filter screen 383 as needed. The motor body 310 is started, causing the fan blade 324 to rotate. Outside air is introduced into the circular groove 323 through the vent 321, and then into the through hole 331. After being treated by activated carbon or absorbent material, it is blown into the testing device 120 for heat dissipation and cooling. This achieves the effect of preventing dust, impurities, or large amounts of moisture from entering the testing device 120 during heat dissipation.
