Description
Technical Field
The application relates to the technical field of galvanometer motors, in particular to a galvanometer motor with a centrally-mounted load.
Background
The galvanometer motor is also called a galvanometer scanning galvanometer (galvanometric scanner), is a special swinging motor, and is used for deflecting a load, and the basic principle is that an electrified coil generates moment in a magnetic field, and the load is controlled to rotate by a certain angle through the moment. Referring to fig. 1, the galvanometer system is a high-speed, high-precision servo control system consisting of a control system and a galvanometer motor, sensors, and a load.
The scanning galvanometer motor structure consists of a stator part, a rotor part and a signal feedback part. The load is typically a mirror or imaging device, often used as an actuator in the optical field to change the angle of the light path. The deflection angle of the scanning galvanometer is limited, usually-20 degrees, and is limited by the size and the manufacturing process of the rotor permanent magnet, the output power of the scanning galvanometer motor is generally smaller, when the rotational inertia of a load is larger, the size parameter of the electromagnetic part needs to be adjusted, so that the external size of the motor is correspondingly increased, and meanwhile, the size of the electromagnetic part is relatively complex to adjust due to the limitation of a structure and an outsourcing piece. Referring to fig. 2 and 3, in the related art, the motor profile of the scanning galvanometer is generally that the front end of the motor is connected to a load by a clamping assembly, and the position sensing part is connected to the rear end of the motor.
For the above related art, the inventor has found that the medium load (transmitting lens) and the clamping assembly are typically bonded by glue using a single-sided clamping groove, and this bonding method has the following drawbacks: 1. when the rotational inertia of the lens is increased, the bonding area of the clamping assembly and the lens needs to be increased synchronously to ensure enough bonding strength, but the clamping assembly is usually made of metal materials, and the load of the motor is increased when the size of the clamping assembly is increased; 2. the single-side lens bonding mode is easy to lead the lens to displace and deform when the motor is vibrated and impacted, thereby reducing the reflection precision; 3. when the motor is vibrated and impacted, the bonding part of the single-side bonding lens needs to bear the feedback impact force of the whole lens, so that the lens is easy to fall off and crack; 4. the lens, the clamping component and the glue expand under the high-low temperature environment to generate stress, and the structure of the single-side clamping groove type lens is easy to crack under the action of local stress;
and the motor body part and the position sensing part are designed on the same side in the related art, the following problems exist in the position relation: 1. when the length and the size of the motor are large, the application with hard requirements on the space on two sides of the motor load is difficult to popularize, namely the applicability of the motor is not high; 2. the scanning galvanometer motor is easy to be interfered by signals, has high requirements on structural design and device model selection, and has high design difficulty; 3. the existing feedback scheme needs to use protective measures in a targeted manner, such as selecting anti-interference cables, shielding materials and the like; 4. when the scanning galvanometer motor fails, the motor body and the position sensing part are integrated, so that failure reasons are not easy to check and analyze.

one end of the load is coaxially bonded with the rotor part through one rotating mechanism, and the other end of the load is coaxially connected with the stator part through the other rotating mechanism; one end of the rotor part, which is far away from the load, is connected with a position sensing part for feeding back the position of the load; and one end of the stator part, which is far away from the load, is connected with an electromagnetic part.
Further, the rotor part comprises a shell and a rotating shaft, wherein the peripheral surface of the rotating shaft is fixedly connected with a limiting pin which is coaxially arranged, the shell is provided with a limiting groove for the limiting pin to move, and the shell is fixedly connected with the base; one end of the rotating shaft is coaxially bonded with the load through the rotating mechanism, and the other end of the rotating shaft is fixedly connected with the position sensing part.

When the rotating shaft of the rotor part is a hollow shaft with built-in magnetic steel, the permanent magnets (magnetic steel) in the rotating shaft are wrapped by the non-magnetic conductive rotating shaft (hollow shaft) more stably, and are not easy to be influenced by external force; and the structure of the rotating shaft does not increase the moment of inertia of the rotor portion. The electromagnetic part and the position sensing part are structurally separated, so that mutual electromagnetic interference between the electromagnetic part and the position sensing part is reduced;
compared with the original galvanometer motor, the single-side motor has longer length, the electromagnetic part and the position sensing part are separated, the motor body at one side of the load is only provided with the stator part and the electromagnetic part, the length of the single-side motor body part is reduced, and the application range of the galvanometer motor is widened; the technical scheme of the application can be suitable for large-size loads; the applicability of the vibrating mirror motor is improved. The electromagnetic part and the position sensing part are arranged separately, so that the electromagnetic part is more convenient to design and easier to manufacture.
The scheme of the application reduces the interference resistance selection requirements of materials such as components, cables and the like, namely the interference resistance of the vibrating mirror motor can be obviously improved by using conventional materials. The vibrating mirror motor has reasonable structure and high reliability, and is more suitable for occasions with high and low temperature, vibration and impact application requirements; and can effectively improve the investigation and the repair of unusual problem, only need open the part of corresponding bad position and just can accomplish the change work.
In summary, the vibrating mirror motor with the centrally-mounted load can effectively reduce the possibility of load falling, cracking, deformation and displacement, improve the applicability of the motor and improve the convenience for checking the failure reasons of the motor.
