The principle of the electronic rocker arm is to provide ±12V stable DC power supply through the power supply, and transmit the operation intention of the operation handle to the executive drive device through the controller and cable to complete the control action.
The driving device of the electronic rocker arm is 12V DC gear motor, which rotates through the gear, of which 12V motor is a high-speed high-performance motor without inertia, characterized by fast start, high speed, no rotational inertia, that is, turn and stop. The principle of the horizontal and pitch electric control of the head boom unit is that when the handle is operated (horizontal and pitch rotation), the potential of X point deviates from 0 reference, and the operational amplifier is passed. The Y point outputs positive or negative voltage to drive the motor D to turn or reverse, so that the head appears horizontal or pitching rotation, until the handle is returned to the center position, the voltage disappears, the motor D stops rotating, and the head stops at the current position. The size of the output Y point voltage can be adjusted by the controller to control the motor speed and adjust the horizontal and pitch execution speed.
The electron rocker arm is a probe tool used in scanning electron microscopy. Its principle is to detect the topological morphology and electrical properties of the sample surface by using the magnetic field generated by the tiny current passing through the probe to interact with the magnetic field generated by the reflected electrons on the sample surface.
The probe of the electronic rocker arm has a very small tip and its size can reach the nanometer level, so it has excellent performance such as high resolution and sensitivity.
By rapidly moving the distance between the probe and the sample, three-dimensional images can be generated, enabling precise detection and analysis of tiny regions in the sample. Therefore, the electronic rocker arm can be widely used in nanomaterials, biology, chemistry and other fields.
The electronic rocker arm consists of a curved elastic beam and a small tip attached to one end. When the electronic rocker arm approaches the surface of the sample, due to the van der Waals interaction force, the beam vibrates slightly, and when the tip touches the surface of the sample, the tip bends to form a tiny elastic pit, which is the basis of atomic resolution imaging.
The scanner controls the electronic rocker arm to scan the surface of the sample, receiving the signal and amplifying it to form an image.
This high-resolution scanning microscopy technique is mainly used for the study of surface morphology, surface reaction, surface structure and electronic structure in the fields of surface physics, chemistry and materials science.
The electronic rocker arm is composed of a vertical arm and a horizontally fixed flat arm, using a magnetic head to read data on the hard disk. The movement of the arm is realized by the motor and the transmission device. When the electronic signal controls the motor, the arm moves to the designated track and sector to read the data. In the process of reading, the reading speed and progress of data are controlled by changing the position of the reading head.
The electronic rocker arm uses magnetic materials to read data by shifting between magnetic poles. Millions of data points are stored on the hard drive, and the electronic rocker arm is able to access these data points quickly and efficiently, thus enabling the reading and storage of data.
The Electronic Rocker arm (EFM) is a scanning probe technology that detects surface topography and chemical composition by scanning the position of the probe on the surface of a sample. During scanning, the distance between the probe and the sample changes as the probe moves.
EFM uses this distance change to detect the impedance change of the scanning probe, thereby obtaining topological and electrical properties of the sample surface. EFM technology can be applied to the research of biomedicine, materials science, electronics and other fields.
