Description

Technical Field

[0001] The utility model relates to the technical field of servo motors, in particular to a servo motor with good dust-proof effect. Background Technique

[0002] A servo motor refers to an engine that controls the operation of mechanical components in a servo system. It is an auxiliary motor indirect speed-changing device that can control speed and position accuracy very accurately. It can convert voltage signals into torque and speed to drive the control object. The rotor speed is controlled by the input signal and can respond quickly. It is used as an actuator in an automatic control system and has a small electromechanical time constant, high linearity, generates electromagnetic interference, and has requirements for the environment. Therefore, it can be used in ordinary industrial and civil occasions that are sensitive to costs.

[0003] The prior art discloses an explosion-proof stepper motor with the application number CN202110854185.2. The invention includes a motor main body and heat dissipation fins. A cleaning component is arranged outside the motor main body. The cleaning component is in contact with the heat dissipation fins in a matching manner, and a linkage component is arranged at the end of the motor main body. The linkage component is docked with the output shaft of the motor main body, and the cleaning component is driven to move on the heat dissipation fins to clean dust through the output shaft of the motor main body. In this explosion-proof stepper motor, through the combined use of the arranged cleaning component and the linkage component, during the continuous use of the motor main body, the dust accumulated on the heat dissipation fins of the motor main body can be automatically cleaned, effectively ensuring the continuous and effective heat dissipation use of the motor main body and ensuring its service life.

[0004] In the first embodiment of the invention during dust removal treatment, the swing amplitude of the second connecting rod is relatively large. Therefore, sufficient swing space needs to be reserved for it during installation, which affects its application range. Although the installation space of the second embodiment of the invention has been improved, when the cleaning brush roller is cleaning, it can only remove dust from the adjacent fins of two groups of heat dissipation fins, and the top of the uppermost heat dissipation fin and the bottom of the lowermost heat dissipation fin cannot be in contact with the cleaning roller, so dust removal treatment cannot be carried out, and the dust removal effect is poor. Moreover, both embodiments one have a common drawback, that is, they ignore that the cleaning component will generate heat due to continuous friction with the heat dissipation fins, which greatly reduces the heat dissipation effect of the heat dissipation fins.
