The working principle of electromagnetic brake
Release time:
2022-10-09
The electromagnetic brake is a connector that transmits torque from the active side to the passive side. Any combination of cutting or braking can be required. The electromagnetic brake has compact structure, simple operation, sensitive response and easy to realize remote control.
The electromagnetic brake is a connector that transmits torque from the active side to the passive side. Any combination of cutting or braking can be required. The electromagnetic brake has compact structure, simple operation, sensitive response and easy to realize remote control. This article will focus on the working principle of electromagnetic brakes and how to choose electromagnetic brakes.
The working principle of the electromagnetic brake When the current of the electromagnetic brake is cut off, the brake pads are separated from the brake disc, and the drive shaft is used to generate the friction torque between the brake disc, the brake pads and the flange to quickly stop. When current passes through the magnetic coil of the electromagnetic brake, the electromagnetic force attracts the brake pads, and the brake pads are used to release the brake disc. Then the drive shaft runs normally or the brake disc starts.
Similar to the principle of electromagnetic braking and motors, the magnetic induction wire cutting magnet or electromagnet coil in the electromagnetic braking process will generate an induced current coil or an induced electromotive force according to the law. The result will convert the kinetic energy of the rotor into electrical energy (power generation). It is usually used in electric locomotives. In the case of high-speed braking, the low-speed braking effect is not ideal, and it is usually used in combination with traditional friction braking.
The performance of the friction material used in the electromagnetic brake directly affects the braking process, and the main factors affecting its performance are the working temperature and temperature rise speed. The friction material should have a high and stable friction coefficient and good wear resistance. Friction materials are divided into metal and non-metal two categories. The former commonly used cast iron, steel, bronze and powder metallurgy friction materials, the latter commonly used leather, rubber, wood and asbestos.
How to choose the model of electromagnetic brake When the load of electromagnetic brake accelerates, the dynamic friction torque must be greater than the sum of the mechanical load torque and the acceleration torque, and the static friction torque must be greater than the torque when the load rotates. Therefore, please refer to the user's simple selection column to calculate the torque multiplied by the safety factor, which is a reasonable torque.
The heating of the electromagnetic brake is caused by mutual friction, which is the main heat source, followed by no-load torque and coil power. Therefore, when the user finds that the product is overheated, the cause should be analyzed in time. It is often due to the difference in heat that causes the torque to drop., Causing the coil to burn. Under normal circumstances, as long as the product temperature of reasonable torque does not exceed the requirements of the E insulation level allowed by the coil, the above situation will not occur. However, continuous operation under high-frequency power combination may result in erroneous operation because the accumulated heat cannot be released. At this time, the product with larger torque value should be improved.
In view of the problem of electromagnetic brake, this paper focuses on the working principle of electromagnetic brake and how to choose electromagnetic brake. It can be seen that the electromagnetic brake has many advantages, but it needs to be selected in combination with the actual situation.
