Release Date:23/08/2019
Single-axis magnetic powder brake working principle:
1. The coil static magnetic powder brake and the magnetic powder clutch are automatic devices that control the input current and change the output transition.
2. When the coil is not energized, the input shaft rotates, and the magnetic powder is pressed against the inner wall of the clamp ring under the action of centrifugal force, and the output shaft is not in contact with the input shaft. At this time, it is in an idling state.
3. When the coil is energized, the magnetic powder generates a magnetic flux under the action of the magnetic force line, so that the output shaft and the input shaft become a rigid body and rotate, and a slip occurs when the overload occurs, and the working state is at this time. Thereby achieving the purpose of transmitting torque. The magnetic dielectric undergoes a change in physical properties under the influence of an electromagnetic field, and the main driven portions of the magnetic powder brake are coupled together.
The structure of the magnetic powder brake:
1. Mechanical body: The mechanical body includes the frame, mechanical connection, mechanical transmission, etc. It is the basis of mechatronics, plays the role of supporting other functional units in the system, transmitting motion and power. Compared with pure mechanical products, the technical performance of the mechatronic system is improved and the function is enhanced. This requires the mechanical body to be compatible with mechanical structure, material, processing technology and geometric size. Versatile, reliable and energy efficient, small, lightweight and beautiful.
2. Detection and sensing part: The detecting and sensing part includes various sensors and signal detecting circuits, and its function is to detect changes in the parameters related to the environment and the external environment during the working process of the mechatronic system, and transmit the information to the electronic control unit. The electronic control unit issues corresponding control to the actuator based on the checked information.
3. Electronic control unit: The electronic control unit also calls the corresponding command with the rhythm to control the entire system to be carried out purposefully.
4. Actuator: The function of the actuator is to drive the movement of the mechanical components according to the instructions of the electronic control unit. Actuators are moving parts and are usually powered by electric drive, pneumatic drive and hydraulic drive.
5. Power source: The power source is the energy supply part of the mechatronics product. Its function is to provide energy and power to the mechanical system to make the system operate normally according to the system control requirements. The way to provide energy includes electrical energy, gas energy and hydraulic energy, mainly based on electrical energy.
