Description

Technical Field

[0001] This utility model relates to the field of vacuum servo motor technology, and in particular to a rear end cover device for a vacuum servo motor. Background Technology

[0002] A servo motor is a motor that controls the operation of mechanical components in a servo system; it is a type of auxiliary motor with indirect speed control. Servo motors enable accurate speed and position control, converting voltage signals into torque and speed to drive the controlled object. For ease of monitoring and control, components such as a stroke encoder and / or brake are typically installed at the rear end of the servo motor. Currently, in existing technologies, the brake and encoder are directly connected to the rear end of the motor shaft. The brake, in particular, cannot be disconnected when not in use, increasing resistance and energy consumption; therefore, braking can only be achieved through electrical control.

[0003] Therefore, there is a need to propose a rear cover device for a vacuum servo motor that is simple in structure and has reliable connection. Utility Model Content
