british interlock hose fittings electro-hydraulic block brake classification valve manifold

The braking effect of the electromagnetic brake is divided into electromagnetic powder brake and eddy current brake, electromagnetic brake friction and other forms. ① electromagnetic powder brake: parher british interlock hose fittings excitation coil is energized, a magnetic field, magnetic magnetization in the magnetic field, the formation of magnetic chains and the fixed magnet and the rotor guide polymerized by the magnetic binding force and the braking friction. Disappears when the excitation current loose powder in a free state, the braking effect lifted. This brake small size, light weight, excitation power, and the braking torque and rotor speed is nothing but powder can cause parts to wear. It is for automatic control for the drive system of a variety of machines.
② electromagnetic eddy current brake: excitation coil is energized, a magnetic field. Brake armature shaft rotary cutting vortex magnetic field lines. Armature and the magnetic field inside the vortex formed by the interaction braking torque. Electromagnetic eddy current brake durable, easy maintenance, speed range; but low aging rate, temperature rise, parher braided hose fittings cooling measures must be taken. This brake commonly used in machines with vertical load.

  Electromagnetic friction brake
③ electromagnetic friction brakes: excitation coil is energized, the magnetic field generated by the magnetic yoke pull the armature, the armature through the coupling member to achieve braking.
Also subdivided into a single dry multi-disc dry electromagnetic brake electromagnetic brake wet multi-plate electromagnetic brake and so on.
There braking power can be divided into power-brake and brake.
Qian Dai electromagnetic brake torque is communicated to the driving side to the driven side of the connector that can be combined according to the free, cut off or braking, to make the use of electromagnetic force action, known electromagnetic clutches, brakes, a response prher british fittings speed fast, and simple structure.
Qian Dai electromagnetic brake function: electromagnetic brake is to stop the machine in a very short period of time and not move live gate means; brakes can also be used in the short term to reduce or adjust the machine's operating speed.
