Description

Technical Field

[0001] The utility model relates to the field of servo motors, and more specifically, to a servo motor with convenient heat dissipation. Background Art

[0002] The servo motor can control the speed and position with high accuracy. It can convert the voltage signal into torque and speed to drive the controlled object.

The side wall of the transmission rod 31 is installed with staggered heat-conducting copper 6 and fan blades 11, and the side wall of the transmission rod 31 is installed with a blocking piece 7.

[0026] An exhaust port 10 is provided on the side wall of the shell 1, and the exhaust port 10 is arranged in the inner cavity of the side door plate 8, and the side wall of the side door plate 8 is provided with an auxiliary hole, and the side wall of the sealing plate 7 is close to the side wall of the exhaust port 10, so as to facilitate the gas in the inner cavity of the shell 1 to be discharged through the exhaust port 10.

[0027] A rotation hole is provided on the side wall of the housing 1 , and the transmission rod 31 is rotatably connected to the rotation hole, so that the stator 2 drives the transmission rod 31 to rotate through the rotor 3 .

[0028] An air inlet hole is provided on the side wall of the shell 1 in the inner cavity of the tail shell 4 . The air inlet hole is arranged in the inner cavity of the L-shaped plate 5 , so that the external air can enter the inner cavity of the shell 1 through the tail shell 4 .

[0030] During use, a technician in this field energizes the stator 2, and then the stator 2 generates a magnetic field and prompts the rotor 3 to drive the transmission rod 31 to rotate, and then the transmission rod 31 drives the gas in the inner cavity of the shell 1 to circulate through the fan blades 11, so as to facilitate the gas to be introduced into the tail shell 4 through the bottom of the tail shell 4, and the gas is blown into the inner cavity of the shell 1 through the inner cavity of the tail shell 4, and then the gas in the inner cavity of the shell 1 discharges the heat carried by the heat-conducting copper 6 through the exhaust port 10.
