tension control brake system is one of the artistic works of our designers. They have strong innovation and design capabilities, endowing the product with an exceptional appearance. Having been produced under the strict quality system, it has been certified to be superior in its stability and durability. Before being shipped out by Sunrise Group (Dongguan) Industrial Co., Ltd, it must pass several quality tests performed by our professional QC team.
In the survey conducted by the company, customers praise our Sunrise products from different aspects, from the trending design to the refined workmanship. They tend to repurchase our products and think highly of the brand value. However, the products are stilled updated as we stick to improve its flaw mentioned by the customers. The products have maintained the leading status in the global market.
We have a serious and responsible attitude toward tension control brake system. At SUNRISE, a series of service policies are formulated, including product customization, sample delivery and shipping methods. We make it a point of satisfying every customer with the utmost sincerity.
Magnetic particles (very similar to iron filings) are located in the powder cavity. When electricity is applied to the coil, the resulting magnetic flux tries to bind the particles together, almost like a magnetic particle slush. As the electric current is increased, the binding of the particles becomes stronger. The brake rotor passes through these bound particles. The output of the housing is rigidly attached to some portion of the machine. As the particles start to bind together, a resistant force is created on the rotor, slowing, and eventually stopping the output shaft.
Electromagnetic clutch & brake set Key Features
Dual shaft structure. Without idel torque. It's easy to assemble with wide band belt pulley in variable speed. Air GAP adjustment, when surface close the effective friction life, can be adjust on line no need to exchange.
Web guiding controller function:
1. support three operation modes: edge-following, line-following and center-alignment.
2. support photoelectric sensor, ultrasonic transducer and CCD Sensor
3. detect sensor’s parameters intelligently, no need to correct the sensor under most circumstances
4. automatic travel measurement, no need to limit the switch mechanically.
5. no overshot integral variable PI algorithm, high accuracy, fast reaction and less error.
Powder Clutch and Brake Application
Due to the feature of the magnetic powder
clutch and brake, they have been widely used in paper making, printing, plastic
items, rubber industry, textile industry, printing and dyeing, wire and cable,
metallurgy industry and tension control of winding and unwinding in roll
material processing industry. A complete set of schematic of tension control
system is as follows.
Note:
The magnetic powder clutch can be also used
in buffering start, overload protection, speed adjustment; the magnetic brake
can also be used in test loading and braking of transmission machinery.
Design reference
First, let us learn the meaning of the
following words:
1. Slip rotational speed: the speed
difference between input shaft and output shaft is magnetic powder clutch, the
rotational speed of output shaft for magnetic powder brake.
2. Slip powder: the powder generated from
the slip rotational speed when the magnetic powder clutch or brake transfer
torque.
The selection of the magnetic powder clutch
or brake rely on the maximum required torque and rotational speed. Because the
temperature of all parts will rise when the slip power is converted into heat,
it is guaranteed that the actual slip power is less than the rated value.
