Sunrise Group (Dongguan) Industrial Co., Ltd has been working on the speeding and improving air clutch's design, testing, and optimization for years so that it is now of stable quality and of reliable performance. Also, the product becomes popular and is known for its durability and dependability in the market for it has been supported by our professional and experienced technical R&D team.
Through our own R&D efforts and stable partnerships with many big brands, Sunrise has expanded our commitment to revive the market after we carried out a series of experiments to work on our brand establishment through honing our techniques of manufacturing our products under the Sunrise and through delivering our strong commitment and brand values to our partners with sincerity and responsibility.
The minimum order quantity of air clutch at SUNRISE is required. But if the customers have any demands, it can be adjusted. The customization service has become mature since establishment with endless efforts placed.
The Leaf type air shaft is suitable for a full range of converting and web production operations, with a fixed leaf design for greatest core and web concentricity. It is ideal for core or coreless winding, and features a 360¡ã radial expanding grip. Its rugged construction and design is available for any diameter or length, in steel, aluminum or lightweight carbon, with special designs available for heavy duty and extra lightweight applications. Shaft weights for your specific application are available upon request.
Structure and working principle
The magnetic powder clutch is composed of active rotor (input shaft) and Yoke with excitation coil. The three parts are assembled relative concentric and form a system which can rotate relatively. The annular gap between active rotor and driven rotor is full of alloy powder which has high magnetic conductivity.
The magnetic powder will be in the state of loose when the current do not pass the excitation coil. The magnetic powder will be thrown on the inner wall of active rotor. In this case, there will not exist the interaction force between the active and driven rotor. So the magnetic powder clutch is in the state of separation, no torque transmission exits.
The magnetic powder in the working chamber will link in a link state under the action of the magnetic flux generated from the Yoke when the current pass the excitation coil. The magnetic powder clutch can transfer torque relying on the shear force generated from magnetic chain and the friction generated from the magnetic powder and working face. In this case, the magnetic powder clutch is in the state of combination.
When the current is cut off, the magnetic flux will disappear with the disappearance of the magnetizing current, the magnetic powder will be in the state of loose under the action of gravity again, and will be thrown on the inner wall of active rotor under the action of the centrifugal force. In this case, the magnetic powder clutch will be in the state of separation again.
The magnetic powder clutch and brake have the same principle, the magnetic powder brake will form as long as the driven rotor of the magnetic powder clutch is fixed.

Basic structure of Clutches
The basic structure of Clutches contains stator of Built-in coil, rotor which filled with Lining and armature plate & spring sheet fixed on the armature cam. The stator is mounted and fixed on a static components directly, such as bracket; the rotor is fixed on rotary shaft by a key; the stator and the rotor are combined to form a magnetic armature by a narrow air signal as a part of the magnetic circuit; the armature plate is opposed to the rotor and maintain a certain clearance; the armature unit for the through shaft is mounted on the shaft through a bearing.
Working principle of Clutches
When the magnetic field coil is energized, the stator generates a magnetic field, the armature plate is sucked and connected, meantime, the spring sheet stretching, other parts remain motionless, the connection action has been generated. When the power is off, the magnetic field disappears, and the armature plate is pulled back to the original position by the spring sheet due to the absence of the magnetic field, meantime, the clearance is formed, and connection disconnected.

In a magnetic particle clutch, an energized coil applies magnetic flux to magnetic particles in a powder cavity causing them to bind together. The binding of the particles causes the driving (rotor) and driven (armature) components to experience drag which causes torque to be transmitted from one to the other via the particles. The strength of the binding (and accordingly, the deceleration torque generated) can be finely controlled by the varying the amount of current provided to the coil.
