Magnetic Powder Brakes For Use With Air Expanded Shafts

The structure of the magnetic particle brake is as follows:
Magnetic particle brakes typically include components such as a main structure, coils, power controllers, and sensors. The main structure includes stator, rotor and brake disc, which is the basic component of magnetic particle brake. The stator is the fixed part of the brake that contains the coil and the magnetic powder to fill the gap. The rotor is the rotating part of the brake that is fixed to the inflatable shaft and connected to the motor or other transmission. The brake disc is a metal disc on the rotor that realizes the braking or braking function through the work of the brake.

The working principle of magnetic particle brake:
It is based on the magnetorheological effect of magnetic particles. When an electric current is passed through the brake coil, the resulting magnetic field causes the magnetic particles that fill the brake gap to become magnetorheological. The rheological properties of magnetic particles make them have the properties between fluids and solids, that is, in the state of no current or low current, magnetic particles behave as fluids and cannot provide braking force; When the current increases, the magnetic particle behaves as a solid, which can provide braking force and achieve a braking effect. By controlling the magnitude and direction of the current, the braking and braking functions of the magnetic particle brake can be realized.

Advantages of magnetic particle brakes:
1) Stepless speed regulation: By adjusting the size of the current, the viewer can achieve stepless speed regulation to meet different work needs.
2) Instantaneous braking: In situations where rapid stop or deceleration is required, the magnetic particle brake can respond quickly and provide instantaneous braking.
3) Low noise: Compared with the traditional braking system, the noise of the magnetic particle brake is lower, making it suitable for environments where noise is required.
4) Simple maintenance: less mechanical part, less wear, low failure rate of magnetic powder brake, and relatively simple daily maintenance.
5) Excellent control: Able to adapt to a variety of different working environments, especially in the scene of frequent start and stop.

Magnetic powder brakes are mainly widely used in the following fields:
1) Textile industry: used for tension control and braking of textile machinery to ensure the stability of fabric production.
2) Printing industry: Achieve precise conveying and tension control in printing equipment to ensure printing quality.
3) Machinery manufacturing: It is widely used in the power control of various mechanical equipment, especially high-precision equipment such as CNC machine tools.
4) Packaging industry: Provide stable operation and control in packaging machinery to ensure the efficiency of the packaging process.
5) Motor drive: In motor applications, magnetic powder brakes can be used to regulate speed and protect the motor.

In general, the following key characteristics need to be considered when selecting a magnetic particle brake:
1) Braking force range: Different types of magnetic particle brakes have different braking force range, and enterprises need to choose according to actual needs.
2) Response time: The response time of the magnetic particle brake affects the speed regulation ability of the equipment. The high-response brakes are able to brake in a very short time.
3) Temperature resistance and corrosion resistance: The industrial environment is complex and changeable, and choosing a magnetic particle brake with high temperature resistance and corrosion resistance can effectively prolong the service life.
4) Ease of installation: Magnetic particle brakes that are easy to install and maintain can save labor costs and time for enterprises.

There are a few things to keep in mind before using a magnetic particle brake:
1) During transportation and installation, pay attention not to let the clutch and brake be subjected to strong impact, vibration and unreasonable impact force.
2) The inside of the product is equipped with magnetic particles, so please do not hit or tilt; The input and output shaft ends of clutches and brakes should not be struck with hard objects, and their bodies should not be placed upright.
3) Before installation, the magnetic powder inside the machine may slide to the side or accumulate due to vibration such as packaging and transportation, which may cause inflexible rotation or difficult rotation.
4) When not used for a long time, do not place the clutch and brake in a wet place for a long time, as the internal moisture will cause rust and cannot be used, or lead to reduced performance.
