The magnetic powder brake is magnetic, ensuring the working operation stability. It has always been used to adjust the stop and loading of the drive speed stop in industrial applications and can control torque tension without other equipment. The power magnetic powder brake will not cause equipment wear loss.
What Is The Magnetic Powder Brake
The magnetic powder brake, also known as magnetic particle brake, is based on the electromagnetic principle, transmitting torque by magnetic particle, which means that the brake operation can be managed and adjusted, to achieve excellent power transmission, no friction and no wear. It has the advantages of fast response speed, simple structure, no pollution, no noise, no impact vibration, energy-saving, etc. It has been widely used in papermaking, printing, plastic, rubber, textile, metallurgy, and other unwinding and winding tension control in coil industries.
Working Characteristics Of The Magnetic Powder Brake
The torque is increased. Even if the drive end and the driven end are not fully connected, the torque will rise to the set torque set by the current setting, and then accelerate at a certain torque. This function will greatly match the thermal capacity of the clutch, suitable for buffering start. If the starting current is controlled, the starting torque will also change rapidly. At the same time, due to use of the magnetic powder with advantages of heat-resistant and wear-resistant, the permissible connection power is large, and continuous slip can be used in the allowable continuous slip power range.
Winding And Unwinding Principle Of The Magnetic Powder Brake
Unwinding
The tension of the unwinding is controlled by the brake torque of the magnetic powder brake. As the continuous reduction of the winding diameter, the braking torque must be continuously reduced. The torque of the magnetic powder brake is automatically controlled by the tension controller so that the tension is constant.
Winding
The final winding speed is normally higher than the line speed of the material, so the magnetic powder clutch working in a slip state, the tension is controlled by the torque of the powder clutch. In order to keep the tension, The torque of the powder clutch brake must be increased or decreased according to the size of the web.
How To Lengthen The Service Life Of The Magnetic Powder Brake
In order to ensure the working quality of the magnetic powder brake, the high-quality magnetic powder must be adopted, which has the advantages of highly magnetic, high magnetic inductance strength, large transmission torque, etc.
The magnetic powder brake should not be operated in a humid environment, so as not to damage the magnetic powder. Relevant maintenance is required to ensure long service life.
The installation environment of the magnetic powder brake should be selected in a dry, ventilated environment, avoiding moisture and dust.
When the magnetic powder clutch and magnetic powder brake are applied to continuous sliding in the winding and unwinding process, the life of the magnetic powder will vary depending on the condition of the use and relative sliding speed, such as the high surface temperature, heavy load, damp, etc. However, when it is usually used under the allowable continuous slip power, the service life of the magnetic powder brake clutch can achieve about 5000 to 8000 hours when the torque is reduced at the rated current. If used at rated torque, since the magnetic powder brake and the magnetic powder clutch can be continuously sliding used, the service life can be extended. In addition, even if at the same slip power, when the sliding speed and the relative rotation speed continue to be in a high state, the lifetime of the magnetic powder is shortened, so it is recommended to set a smaller relative speed. Generally, relative to the allowable continuous slip power, if it can be used under relatively good conditions, it is also possible to lengthen the service life of the magnetic powder.

Magnetic powder brake
The magnetic powder brake is a novel transmission element, adopting powder as the medium, magnetic particle chain formed to transmit torque when energized, which is mainly composed of inner rotor, outer rotor, magnetic coil and magnetic powder. When the coil is not powered, the active rotor rotates. Due to the centrifugal force, the magnetic powder is smashed on the inner wall of the active rotor, and there is no contact between the magnetic powder and the driven rotor. After the DC power is turned on, the electromagnetic field is generated, and the working medium magnetic powder forms a magnetic powder chain with the magnetic line action, which connects the inner rotor and the outer rotor, thereby achieving the purpose of transmitting and brake torque.
Air shaft
The air shaft is based on the principle of air compression. The outer diameter of the shaft is changed and the roll core is privileged, facilitates the transmission of the material on the production line. It is not necessary to unload the whole shaft for unloading materials of the air shaft and the materials can be taken away after direct venting. Since its width is not large, the natural operation is also more convenient. The air shaft is selected for the machine with a lightweight and small width.
All-in-one web guide system
The servo all-in-one web guide system is working, when the web guide sensor transmits the infrared light, ultrasonic, particle beam, or monochromatic light-detecting the web, sending the signal to another sensor. After the sensor finds the web offset, according to the commands set in advance, the controller makes the web guide steering structure swaying and correct the web edge position. The automatic web guide system adopts a photoelectric sensor, ultrasonic sensor, or CCD sensor to detect the edge of the web, and the measured portion deviation signal will be sent into the sensor, and the motor is controlled by the manipulation module.
Web Tension control system
The servo web tension control system is mainly used for automatic folding mask machine. According to the loop tension control, a servo tension control system is divided into open loop and closed loop. Open-loop tension control system is composed of a tension sensor, a tension controller and a tension controller, with no tension value feedback. Closed-loop tension control system is composed of a tension sensor, a tension controller, a magnetic powder brake, a magnetic powder clutch, which has a tension value feedback, according to the feedback tension value, adjusting the control, making the result in a right state. The closed loop control system is more stable. Nowadays, the automatic tension control system is generally adopted, and the generated additional tension will change reversely with the change of unwinding tension, compensating the tension to keep the tension constant.
