The electromagnetic brake is a kind of ideal of modern industrial automation equipment, main power transmission and motion control function in the mechanical transmission. Has the advantages of compact structure, simple operation, quick response, long service life, reliable operation, easy to realize remote control.
A electromagnetic eddy current brake: magnetic field excitation coil is energized. Brake shaft armature of rotary cutting magnetic field lines generated vortex. Eddy current and magnetic field of the armature in the interaction between the formation of braking torque. The electromagnetic eddy current brake durable, convenient repair, wide range of speed regulation; but low efficiency and low, Wen Shenggao, must take the cooling measures. The brake is commonly used in a vertical load machinery.
B electromagnetic powder brake: magnetic field excitation coil is energized, the magnetic powder under the action of magnetic field, magnetization, magnetic particle chain formation, and polymerization in the magnetizer is fixed between the rotor and the braking is realized by magnetic particle, adhesion and friction. The excitation current vanishes when the powder is in free loose state, brake release. The brake has the advantages of small volume, light weight, small excitation power, and brake torque and rotating speed has nothing to do, by adjusting the current to adjust the brake torque, but will cause parts wear particle. It is suitable for automatic control, drive system is suitable for various kinds of machines.
C electromagnetic friction brake: electromagnetic brake excitation coil generates magnetic field, the magnetic yoke can attract the armature, an armature system through connecting pieces.
