How should the tension be adjusted when using the electromagnetic brake?
Release time:
2022-08-03
The electromagnetic brake is equipped with an excitation coil. The soft magnetic data and the coil around the air gap form a magnetic circuit. The electromagnetic brake is mainly composed of an automatic rotor, a driven rotor and a fixed bracket. Some soft magnetic powder is filled between the automatic rotor and the driven rotor of the electromagnetic brake. When the electromagnetic brake coil is energized, the current forms a magnetic field in the magnetic circuit.
The electromagnetic brake is equipped with an excitation coil. The soft magnetic data and the coil around the air gap form a magnetic circuit. The electromagnetic brake is mainly composed of an automatic rotor, a driven rotor and a fixed bracket. Some soft magnetic powder is filled between the automatic rotor and the driven rotor of the electromagnetic brake. When the electromagnetic brake coil is energized, the current forms a magnetic field in the magnetic circuit. So how to adjust the tension when using the electromagnetic brake?
1. The greater the excitation current, the greater the magnetic induction intensity and electromagnetic attraction in the working gap. When the excitation current is disconnected, the magnetic powder will be in a non-excited state and separated from the control of the brake. Conversely, the transmitted torque will be smaller. Adjusting the size of the excitation current can adjust the size of the transmission torque.
2. The magnetic powder between the automatic part of the electromagnetic brake and the driven part is connected into a chain. At this time, torque can be transmitted due to friction between the components, and the transmitted torque becomes large. Due to the centrifugal force, the magnetic powder is pressed on the inner wall of the cylinder, there is a gap between the magnetic powder and the rotor, and the clutch does not generate idle torque, so there is almost no heat.
3. When the electromagnetic brake coil is not energized and the cylinder rotates, the key to the quality of the electromagnetic brake is the quality of the magnetic powder function. The higher the magnetic permeability of the magnetic powder, the smaller the remanence, and the better the control characteristics of the electromagnetic brake.
4. Because the automatic part of the electromagnetic brake runs at high speed, it will generate a lot of heat, so the magnetic powder needs better heat resistance and wear resistance. So how to control the voltage of the magnetic powder clutch during use? When the electromagnetic coil of the electromagnetic brake and the electromagnetic clutch is energized, the coil is excited to generate the attraction force required by the clutch and brake and perform work.
The varistor may be used as a discharge element. Its function is to limit the voltage when the electromagnetic brake and the electromagnetic clutch are properly controlled. The varistor can easily set the limit voltage. The volume of the element is very small and can fully cope with the surge energy. Through the reasonable choice of rheostat, electromagnetic brake and electromagnetic clutch, it can be used without destroying the original characteristics. If the selected voltage is higher than the appropriate limit voltage, the control contacts will burn out and the power supply will be damaged. On the contrary, when the lower limit voltage is selected incorrectly, the power supply voltage will burn out the varistor or damage the power supply equipment. In addition, even if this phenomenon does not occur sometimes, it is easy to cause the armature to become longer when the armature is released.
It should be noted that the torque of the electromagnetic brake can be changed, but it cannot be changed by itself. It needs to be used in conjunction with the controller (manual tension controller/fully automatic tension controller) to change the input current of the electromagnetic brake through the controller to change the tension of the electromagnetic brake.
