CKLASER 3D Galvanometer
The fundamental structure of the vibrating lens: The vibrating lens is composed of three parts: stator, rotor, and detection sensor. The galvanometer adopts a permanent magnet as the magnetic core, and the detection sensor imitates the galvanometer as a capacitive sensor. The digital galvanometer is a grating ruler detection sensor. A capacitance sensor detects a small change in the capacitance of the sensor when the motor swings, converts the change in capacitance into an electrical signal, feeds it back to the controller, and then performs closed-loop control. The grating ruler sensor measures the actual deflection viewpoint through the grating ruler, and then converts it into an electrical signal, which is fed back to the controller for closed-loop control. Due to the fact that the rotor is a coil, while the coil is relatively large in volume and has a large moment of inertia, it is not conducive to rapid response, so it is not currently used at all. The dynamic magnetic type has excellent rapid response function due to its small volume and small inertia, as the hollow cylindrical magnetic core is tightly installed on the rotating shaft.
The principle of laser galvanometer: When a position signal is input, the swinging motor (laser galvanometer) will swing a certain angle according to a certain voltage and angle conversion ratio. The entire process adopts closed-loop feedback control, which is jointly operated by five control circuits: position sensor, error amplifier, power amplifier, position discriminator, and current integrator. The principle of digital laser galvanometer is to convert analog signals into digital signals based on the principle of analog laser galvanometer.
The galvanometer,for vinyl cutting, silicon cutting,Lettering film cutting, also known as the laser marking machine galvanometer, high-speed optical scanning galvanometer, scanning head, etc., is an important component of the laser marking machine.for vinyl marking, silicon marking, letter film marking.
The fundamental operating principle of electric motors: Electric motors use magnetic fields as the medium and electromagnetic induction to complete energy transformation, so there must be a magnetic circuit for conducting magnetic flux and a circuit for conducting current inside. When an electric motor undergoes energy transformation, it should have two major components for relative motion: the component that establishes the excitation magnetic field and the induced component. The moving component is called the rotor, and the stopped component is called the stator. The generator absorbs mechanical power from the mechanical system and outputs electrical power to the electrical system; Electric motors absorb electrical power from the electrical system and output mechanical power to the mechanical system. During the internal energy transformation process of the motor, there is electrical energy, mechanical energy, magnetic field energy, and thermal energy. During this process, thermal energy is generated by the internal energy loss of the motor, and should be minimized in design. For an electric motor, the electrical energy input from the power source=energy storage increment in the coupled electromagnetic field+internal loss energy of the motor+output mechanical energy. For a generator, the mechanical energy input from the mechanical system=energy storage increment in the coupled electromagnetic field+internal loss energy of the motor+output electrical energy.
