The Advantages And Disadvantages Of Magnetic Powder Brakes Can Be Reflected In These Aspects

The magnetic powder brake uses magnetic powder to transmit torque according to the electromagnetic principle, and the transmitted torque is substantially linear with the exciting current. Therefore, as long as the magnitude of the exciting current is changed, the magnitude of the torque can be easily controlled. Under normal conditions, the excitation current is proportional to the torque it communicates in the range of 5% to 100% of the rated torque.

Magnetic particles are small, highly magnetized and wear-resistant iron particles. Each iron particle has a volume of about 40 microns. When the magnetic coil is not conductive, the torque is not transmitted to the clutch or the magnetic powder brake. Due to the action of the magnetic force, the hardening phenomenon occurs, and the magnetic powder is attracted. The continuous slip will transmit torque from the clutch or the brake. Ingredients: main components - iron, cobalt, nickel Use: Suitable for slitting machine, laminating machine, coating Magnetic powder clutches, brakes, single shaft, double shaft, hollow shaft, etc. for machines, printing machinery, food machinery, bag making machinery, etc., can restore tension and balance torque.

Do you know where you can distinguish the pros and cons of the magnetic powder brake? . The magnetic powder brake is provided with an excitation coil, and the soft magnetic material has a friendly gap around the coil to form a magnetic circuit. The tension consists of the active rotor, the driven rotor, and the three units that are firmly supported. Some soft magnetic magnetic powder is added between the active rotor and the driven rotor.

Magnetic powder brake:

1. The active department of the magnetic powder brake is to operate at high speed, which will inevitably generate a lot of heat. Therefore, the magnetic powder must have good heat resistance and wear resistance.

2. When the current is disconnected, the magnetic powder is in an unexcited state, leaving the control of the brake. Determining the advantages and disadvantages of the magnetic powder brake is the performance of the magnetic powder. The higher the magnetic permeability of the magnetic powder and the less the residual magnetism, the better the control characteristics of the magnetic powder brake.

3. When the coil is energized, the current creates a magnetic field in the magnetic circuit. The magnetic powder between the active member and the driven member is connected in a chain shape, and the torque can be transmitted due to the friction between the members. The larger the current is encouraged, the more the magnetic strength in the gap is increased, the electromagnetic attraction is increased, and the torque transmitted is increased; otherwise, the torque transmitted is reduced. By adjusting the magnitude of the excitation current, the magnitude of the relay torque can be adjusted.
