When the exciting coil of the brake is connected with the rated voltage (DC), the electromagnetic force pulls in the armature, which makes it separate (release) from the brake disc, and then the drive shaft runs normally or starts with the brake disc. When the transmission system is separated or powered off, the brake is powered off at the same time, and the spring puts pressure on the armature, which forces the friction torque between the armature disc and the flange disc. Stop the drive shaft quickly. In the brake heat dissipation environment, the drive shaft is in continuous operation for a long time. If conditions permit, the brake work can maintain the voltage conversion to 70%–80% of the rated voltage to reduce heat.
Four thousand Dai electromagnetic brakes
chain-tail electromagnetic brake
A mechanical part that stops or slows down a moving part in a machine Commonly known as brake, brake. The Qian Dai electromagnetic brake is mainly composed of a brake frame, brake parts, and a control device. Some electromagnetic brakes are also equipped with an automatic adjustment of the brake gap. In order to reduce the braking torque and structural size, electromagnetic brakes are usually installed on the high-speed shaft of the equipment, but large equipment with high safety requirements (such as mine elevators, elevators, etc.) should be installed on the low-speed shaft near the working part of the equipment.
Some electromagnetic brakes have been standardized and serialized and are manufactured by professional factories for selection.
The Qiandai electromagnetic brake is an ideal automatic actuator in modern industry. It mainly plays the roles of power transmission and motion control in mechanical transmission systems. It has the advantages of a compact structure, simple operation, sensitive response, long life, reliable use, easy remote control, and so on.
It is mainly matched with a series of motors. Widely used in metallurgy, construction, the chemical industry, food, machine tools, stage, elevator, ship, packaging, and other machinery, and in power failure (risk) braking and other occasions.
The moment of resistance that must be applied to stop or slow down the mechanically moving parts is called the braking moment. Braking torque is the basis of the design and selection of brakes, and its size is determined by the type of machinery and working requirements. The performance of friction materials (brake parts) used on the brake directly affects the braking process, and the main factors affecting its performance are working temperature and temperature rise rate. The friction material should have a high and stable friction coefficient and good wear resistance. Friction materials can be classified into metal and non-metal categories. The former commonly used cast iron, steel, bronze, and powder metallurgy friction materials, the latter leather, rubber, wood, and asbestos.
The use of electromagnetic effect brakes is divided into electromagnetic powder brakes, electromagnetic eddy current brakes, electromagnetic friction brakes, and other forms.
1: Electromagnetic powder brake: when the excitation coil is energized, a magnetic field is formed. The magnetic powder is magnetized under the action of the magnetic field, forming a magnetic powder chain and polymerizing between the fixed magnet and the rotor. The braking is realized by the binding force and friction force of the magnetic powder. When the excitation current disappears, the magnetic powder is in a free and loose state, and the braking effect is relieved. The brake is small in size, light in weight, and small in excitation power, and the braking torque has nothing to do with the rotating speed, but the magnetic powder will cause parts to wear. It is easy to automate and suitable for all kinds of machine drive systems. 2: Electromagnetic eddy current brake: the magnetic field is formed when the excitation coil is energized. The armature on the brake shaft rotates and cuts the magnetic lines of force, creating eddy currents. The eddy current in the armature interacts with the magnetic field to form the braking torque. Electromagnetic eddy current brakes are durable, easy to maintain, and have a wide speed range. However, at low speeds, the efficiency is low and the temperature rise is high. Therefore, heat dissipation measures must be taken. This brake is often used on machines with vertical loads. (3) Electromagnetic friction brake: the excitation coil is energized to generate a magnetic field, which absorbs the armature through the magnetic yoke, and the armature realizes the braking through the connecting parts.
In addition, it is subdivided into dry single-disc electromagnetic brakes, dry multi-disc electromagnetic brakes, wet multi-disc electromagnetic brakes, and so on.
And the braking mode can be divided into energized braking and power-off braking.
Qian Dai electromagnetic brake is a kind of active side torsion to the passive side of the connector that can be free according to the need to combine, cut off, or brake because of the use of electromagnetic force to act, called the electromagnetic clutch, brake, with fast response speed, simple structure, and other advantages.
Qian Dai's electromagnetic brake function:
Electromagnetic brakes are used to make the machine stop running in a very short time and brake the movement of the device. Brakes can also be used in the short term to reduce or adjust the speed of the machine.
The brake is composed of a magnetic yoke, an excitation coil, a spring, a brake disc, an armature, a spline sleeve, mounting screws, etc. The brake is installed on the rear end of the flange of the equipment (or motor); the drive shaft and spline sleeve are connected with the brake disc.
When the exciting coil of the brake is connected with the rated voltage (DC), the electromagnetic force pulls in the armature, which makes it separate (release) from the brake disc, and then the drive shaft runs normally or starts with the brake disc. When the transmission system is separated or powered off, the brake is powered off at the same time, and the spring puts pressure on the armature, which forces the friction torque between the armature disc and the flange disc.
