Description

Technical Field

[0001] This utility model belongs to the field of automation technology, and in particular relates to a servo motor with good dustproof effect. Background Technology

[0002] Servo motors are actuators widely used in automatic control systems. Their function is to convert received electrical signals into angular displacement or angular velocity output on the motor shaft. Their main characteristics are fast response, precise control of position, speed and torque, and advantages such as high efficiency, high precision and good controllability.

[0003] In many industrial environments, such as manufacturing, mining, and construction, the air often contains a large amount of dust. Servo motors contain precision electronic components and mechanical parts, such as encoders and bearings. If servo motors lack effective dust protection measures, dust or dirt will penetrate into the motor, causing wear, jamming, or damage to electronic components and mechanical parts, thus affecting the motor's performance and lifespan. However, existing dustproof components such as dust covers are all integrally molded, which is not only inconvenient for transportation and storage, but also difficult to modify or replace locally. Therefore, a servo motor with good dustproof performance is needed to solve the above problems. Utility Model Content
