Description

Technical Field

[0001] This utility model relates to the field of servo motor technology, specifically a dustproof servo motor. Background Technology

[0002] A servo motor is a type of motor used in servo systems to control the operation of mechanical components; it belongs to the category of auxiliary motors and indirect speed-changing devices. It converts voltage signals into torque and speed to drive the controlled object, and its rotor speed is controlled by the input signal, enabling rapid response. In automatic control systems, servo motors are used as actuators, possessing characteristics such as low electromechanical time constant, high linearity, and low starting voltage. They convert received electrical signals into angular displacement or angular velocity output on the motor shaft. Servo motors are mainly divided into two categories: DC and AC servo motors. Their main characteristic is that they do not rotate when the signal voltage is zero, and their speed decreases uniformly as the torque increases. Servo motors have advantages such as high precision, high speed performance, programmability, reliability, and energy efficiency, and are therefore widely used in industrial automation, electronic equipment, transportation, printing and packaging, and robotics. When selecting a servo motor, factors such as the parameters of the mechanical components, the type of controller, the motor model, the type of driver, and the control method need to be considered. Simultaneously, when using a servo motor, attention must be paid to its maintenance and upkeep, such as regularly inspecting the servo motor's fixed components, output shaft, encoder connection cable, and power connector, and promptly cleaning dust and oil.

[0003] According to patent number CN206422625U published on the China Patent Network, this utility model provides a dustproof servo motor, belonging to the field of motor technology. It solves the problem of data transmission failure caused by dust accumulation at the interface of existing servo motors. This dustproof servo motor includes a body and a drive shaft. The front end of the body has an integral flange. One end of the drive shaft extends horizontally out of the body and has a flat key. Several parallel heat dissipation grooves are formed on both sides of the body. The rear end of the body is fixed with a rear end cover corresponding to the shape of the body by an internal hexagonal nut. A convex component is provided on the top of both the body and the rear end cover, and the convex component is fixed by an internal hexagonal nut. The interior of the convex component is a hollow structure and communicates with the interface inside the servo motor. A power connection hole and a feedback connection hole are respectively formed on one side of each of the two convex components. This utility model achieves better dustproof performance by fixing two convex components to the body.
