To meet the growing demand for high-precision, heavy-load, and efficient drives, researchers have innovatively integrated liquid cooling technology and dual-axis output design within the technical framework of AC permanent magnet synchronous servo motors, giving rise to liquid-cooled dual-axis AC permanent magnet synchronous servo motors. With their superior heat dissipation performance and outstanding mechanical adaptability, this motor has become a key element in modern industrial production lines and plays an irreplaceable role.

[0003] The liquid-cooled double-axle permanent magnet synchronous servo motor disclosed in the patent application with reference publication number CN217159438U is a liquid-cooled double-axle permanent magnet synchronous servo motor. A cooling channel is set in the base, and the heat generated by the internal components of the base is cooled by the coolant flowing in the cooling channel. Compared with the existing air cooling and natural cooling methods, the motor power density can be further improved, and the motor performance and efficiency can be improved.

[0004] Comprehensive analysis of the above reference patents shows the following defects: Existing liquid-cooled double-axle AC permanent magnet synchronous servo motors and use methods usually use flowing coolant to cool the heat generated by the motor.

[0025] Through the mutual cooperation among the gear ring 52, the first large gear 73, the pinion 74, the second large gear 76, the cam 77 and the coolant pumping mechanism 78, the gear ring 52 and the fan blade 53 are driven to rotate during the rotation of the two rotor shafts of the dual-axis synchronous rotor body 51.

[0026] The embodiment of the present invention further provides a method for using a liquid-cooled double-axle-extended AC permanent magnet synchronous servo motor, using a liquid-cooled double-axle-extended AC permanent magnet synchronous servo motor, and the specific method includes the following steps: Step 1: After the stator mechanism 4 is energized, a rotating magnetic field is formed, and the dual-axis synchronous rotor mechanism 5 rotates to output torque. During the operation of the motor, since coolant flows between the cooling pipe mechanism 8, the spiral heat dissipation pipe 9 and the two liquid cooling mechanisms 7, as the dual-axis synchronous rotor mechanism 5 rotates, the two rotor shafts of the dual-axis synchronous rotor mechanism 5 rotate to drive the two liquid cooling mechanisms 7 to work respectively; Step 2: The liquid cooling mechanism 7 is operated to extract and discharge the coolant, so that the coolant circulates between the cooling pipe mechanism 8, the spiral heat pipe 9 and the two liquid cooling mechanisms 7. During the operation of the liquid cooling mechanism 7, as the two rotor shafts of the dual-axis synchronous rotor body 51 rotate, the gear ring 52 and the fan blades 53 are driven to rotate. The gear ring 52 rotates to drive the first large gear 73 and the small gear 74 to rotate, thereby driving the second large gear 76 and the cam 77 to rotate. Through the transmission deceleration effect between multiple gears, the purpose of reducing the rotation speed of the cam 77 is achieved. As the cam 77 rotates, the bottom plate 784 is intermittently pushed downward. Under the elastic action of the spring 785, the bottom plate 784 moves up and returns to its original position.

During the rapid rotation of the fan blade 53, the hot air in the casing 1 is quickly drawn out to achieve the effect of air cooling inside the casing 1. At the same time, the speed of air flow around the spiral heat exchange tube 711 is accelerated, thereby accelerating the cooling speed of the coolant in the spiral heat exchange tube 711 and improving the overall heat dissipation efficiency. The two fan blades 53 on the two rotor shafts of the dual-axis synchronous rotor mechanism 5 are symmetrically arranged, which can respectively draw the air inside the casing 1 to the outside. During the flow of the coolant inside the cooling tube mechanism 8 to the right liquid cooling mechanism 7, the heat generated by the motor when working is taken away by heat exchange, thereby reducing the temperature inside the casing 1. Step three, during the process of the coolant in the spiral heat dissipation tube 9 flowing into the left liquid cooling mechanism 7, since the spiral heat dissipation tube 9 is in contact with the inner wall of the casing 1, and the outer wall of the casing 1 has multiple annular heat dissipation fins 10, the spiral heat dissipation tube 9 transfers the heat in the internal coolant to the annular heat dissipation fins 10, and then the annular heat dissipation fins 10 are used to transfer the heat to the external air, further reducing the temperature of the coolant, so that the coolant circulates and brings out the heat generated by the operation of the motor, wherein the stator mechanism 4 has tooth slots and three-phase AC windings therein, these windings will generate a rotating magnetic field after being energized, the dual-axis synchronous rotor body 51 is composed of multiple permanent magnets, punching sheets and two rotor shafts, and the magnetic field waveform is a sine wave, these permanent magnets will rotate synchronously under the action of the rotating magnetic field generated by the stator mechanism 4, and detection mechanisms are arranged on the left and right sides of the casing 1, the detection mechanisms are used to detect the position and speed of the dual-axis synchronous rotor body 51, and realize high-precision servo control of the motor, and the detection mechanisms belong to the prior art known to technicians in this field.
