Introduction

In the industrial control industry, for some strip-shaped and linear-type products, it is often necessary to control the tension to meet production requirements. The tension controller is a type of instrument that controls such tension. It can directly set the required controlled tension value and then directly input the signal from the tension sensor (generally at the millivolt level) as the tension feedback value. After comparing, the deviation is input into PID and other controllers for processing, and it is preferably output to the peripheral actuator to control, ultimately achieving the goal of minimizing the deviation and having the fastest system response. The tension controller also has the so-called manual control function, which generally means that humans can give a certain output value to the actuator (often the electrical current of the motor) through the tension controller; some tension controllers also have roll diameter calculation function, which is generally applied in winding equipment, with winding and unwinding distinctions; in addition, there is the taper adjustment function, which can directly set some process requirements for the winding taper inside the controller.

Magnetic powder clutch/brake description:
The magnetic powder clutch and brake are composed of the transmission unit (input shaft) and the driven unit (output shaft). In the space between the two units, there is granular magnetic powder (volume approximately 40 micrometers). When the magnetic coil is not conducting electricity, the torque will not be transmitted from the transmission shaft to the driven shaft. However, if the coil is electrified by electromagnetic induction, due to the magnetic force, the magnetic powder will be attracted and a hardening phenomenon will occur. In the continuous sliding process, the torque will be transmitted.
A. Magnetic powder clutch series
* The magnetic powder clutch is a superior automatic control element. It uses magnetic powder as the working medium and the excitation current as the control means to achieve the purpose of controlling braking or transmitting torque. The output torque has a good linear relationship with the excitation current and is independent of the speed or slip. It has the advantages of fast response and simple structure. It is widely used in tension automatic control systems of related winding devices such as wires, cables, packaging, printing, papermaking and paper product processing. The magnetic powder clutch is also used for buffer starting, overload protection, speed regulation, etc.
* Working principle:
* Static coil type magnetic powder clutch and magnetic powder brake are control input current to achieve the automation of changing output torque.
* When the coil is not electrified, the input shaft rotates, and the magnetic powder is pressed against the inner wall of the clamp ring under the action of centrifugal force. The output shaft is not in contact with the input shaft, and this is the idle state.
* When the coil is electrified, the magnetic powder generates magnetic chains under the action of magnetic lines of force, thereby making the output shaft and the input shaft become a rigid body and rotate. In the case of overload, a slip occurs, and this is the working state. Thus, the purpose of transmitting torque is achieved. Characteristics
1. Torque is directly proportional to the excitation current within the specified torque range, and can be used as a linear regulating element.
2. The output torque is constant because the magnitude of the torque depends solely on the magnitude of the excitation current and is independent of the slip speed.
3. The commutation is frequent, the response is fast, the frequency is high, reaching 40-60 times per minute, and it can be widely applied in rapid working conditions and high-frequency scenarios.
4. The power amplification factor is high, and a small excitation current can control a large transmission power, making it easy to achieve automatic control.
5. The operation is stable, with no vibration, no shock, and no noise during startup, operation, and braking.
6. Overload protection: in the case of torque overload, the automatic slip operation plays the role of overload protection.
7. Small in size, light in weight. Installation is convenient, and the service life is long. Purpose
1. It can be used for the clutch effect and torque braking during the torque transmission process.
2. It is applicable to constant tension control systems, such as printing machines, slitting machines, laminating machines, coating machines, paper machines, drawing machines, cable winding machines, as well as metal sheet, strip, film processing equipment and textile machinery, etc.
3. It can replace ordinary clutches and be used in the rapid disengagement of machine tools, numerical control devices, computers, wide-format printers and various precision positioning machinery.
4. As an overload device, it can be applied in mining hoisting machinery, lifting machinery and cement, steel and other mechanical equipment, enabling the prime mover to start without load, gradually load, and improve the load capacity of the equipment.
5. Stepless speed regulation, with sensors and control circuits, can achieve stepless speed regulation, especially for fine adjustment of speed at high rotational speeds and speed regulation systems with small power.
6. In overload protection, when an accident occurs in the working system and the torque exceeds the limit, the clutch automatically slips, thereby protecting the mechanical equipment and the prime mover.

B. Magnetic Powder Brake Series
* The magnetic powder brake is a superior automatic control component. It uses magnetic powder as the working medium and the excitation current as the control means to achieve the purpose of controlling braking or transmitting torque. The output torque has a good linear relationship with the excitation powder current and is independent of the speed or slip, and has the advantages of fast response speed and simple structure. It is widely used in tension automatic control systems of related winding devices such as printing, packaging, paper making and paper product processing, textile, dyeing, wires, cables, rubber and leather, metal foil and strip, etc. The magnetic powder brake can also be used as an analog loader and is widely used for power and efficiency measurement of motors, internal combustion engines, gearboxes and other power and transmission machinery.
* Working principle
* The magnetic powder brake is a new type of transmission element that uses magnetic powder as the medium and forms a magnetic powder chain to transmit torque under the condition of energization. It mainly consists of an inner rotor, an outer rotor, an excitation coil and magnetic powder.
* When the coil is not energized, the driving rotor rotates. Due to the centrifugal force, the magnetic powder is thrown onto the inner wall of the driving rotor, and there is no contact between the magnetic powder and the driven rotor. The driving rotor rotates idly.
* After connecting the DC power supply, an electromagnetic field is generated, and the working medium magnetic powder forms a magnetic powder chain under the action of the magnetic force lines, connecting the inner and outer rotors, thereby achieving the purpose of transmitting and braking torque.
