Magnetic Particle Brakes is based on the electromagnetic principle and uses magnetic powder to transmit torque. It has the advantages of excitation current and transmission torque that are basically linear. It can transmit a certain torque regardless of slip, has fast response speed, and simple structure.
Magnetic Particle Brakes are widely used in braking, loading, and unwinding tension control in winding systems for different purposes in various machines. They are a multi-purpose automatic control component with superior performance.
In the dynamic realm of robotics, where precision and control are paramount, engineers constantly seek innovative solutions to enhance performance. Magnetic Particle Brakes have emerged as a crucial component in the robotics landscape, offering a unique set of advantages that contribute to their widespread adoption.
Magnetic Particle Brakes operate on the fundamental principles of magnetism and rheology. The core of these brakes contains ferromagnetic particles suspended in a fluid. When a magnetic field is applied, these particles align themselves with the field, creating a network that restricts the movement of the brake’s rotating elements. The strength of the magnetic field determines the braking torque, providing a precise and controllable means of regulating motion.
Top 2 Advantages of Magnetic Particle Brakes in Robotics
