introduction：A brake that uses electromagnetic effects to achieve braking，Divided into electromagnetic powder brake and electromagnetic eddy current brake two forms（See picture[Electromagnetic brake diagram]）。①Electromagnetic powder brake：An exciting coil forms a magnetic field when it is energized，Magnetic particles are magnetized by a magnetic field,Forming a magnetic powder chain,And polymerized between the fixed magnetic conductor and the rotor，Braking is achieved by the binding force and friction force of magnetic particles。When the excitation current disappears, the magnetic powder is in a free and loose state，Release of braking。This brake is small in size，Light weight,Low excitation power,And the braking torque has nothing to do with the rotating speed，But magnetic particles can cause parts to wear out。It facilitates automatic control，apply
