2022-10-18
Electromagnetic brakes are mainly matched with series motors and are widely used in the metallurgical industry. Construction. The chemical industry. Food. Machine tools. Phase. The elevator. Vessels. Packaging machinery and braking in the event of electrical failure.
This paper introduces the characteristics and application of electromagnetic brake, the mechanical parts that stop or slow down the moving parts of the machine. Commonly known as automatic brake, brake. The brake is mainly composed of automobile brake frame, brake parts and control device. Some electromagnetic brakes are also equipped with brake components that automatically adjust the gap. In order to reduce the braking torque and structural design size, the brake is usually installed on the high-speed shaft of a device, but large mechanical equipment (such as mine hoists, elevators, etc.) with high technical requirements for enterprise safety should be installed on the low-speed shaft close to the equipment management part.
Some broken bridge aluminum doors and windows have been standardized and serialized, and manufactured in professional factories for selection. The electromagnetic brake is mainly matched with the motor of the product series. Widely used in metallurgy, construction, chemical, food, machine tools, stage, elevators, ships, packaging and other machinery, as well as in the power (insurance) braking and other occasions.
The resistance torque that must be applied to stop or slow down the running parts of the mechanical equipment can be called the braking torque. The braking torque is the basis for the design and selection of electromagnetic brakes, and its magnitude depends on the type of machinery and work requirements. The performance of the friction material (brake parts) used in the electromagnetic brake can directly affect the braking process, and the main economic factors affecting its performance are the working environment temperature and temperature rise speed. The main friction material should have a high and stable coefficient of friction and good wear resistance.
The electromagnetic brake has the advantages of compact design, simple operation, sensitive response, long service life, safe and reliable use, and easy to realize remote control in China. It is an ideal automatic actuator in modern industry and plays a role in driving and controlling motion in the mechanical transmission system.
Electromagnetic brakes are mainly matched with series motors and are widely used in the metallurgical industry. Construction. The chemical industry. Food. Machine tools. Phase. The elevator. Vessels. Packaging machinery and braking in the event of electrical failure. The resistance torque when the mechanical moving parts stop or slow down is called the braking torque. The braking torque is the basis for the design and selection of electromagnetic brakes, and its size is determined by the mechanical type and working requirements.
Electromagnetic brake can be divided into electromagnetic powder electromagnetic brake, electromagnetic eddy current electromagnetic brake and electromagnetic friction electromagnetic brake. Electromagnetic powder brake: When the excitation coil is energized, a magnetic field is formed, and the magnetic powder is magnetized by the magnetic field to form a magnetic powder chain, which is gathered between the fixed magnetizer and the rotor. Braking is achieved by magnetic particle binding force and friction. When the excitation current disappears, the magnetic powder is in a free loose state, and the braking system function can be released. This electromagnetic brake is small in size. Light weight, low excitation power, braking torque and speed are independent of components, but magnetic particles will cause component wear, easy to automatically control, suitable for various mechanical transmission systems.
Electromagnetic eddy current electromagnetic braking: When the excitation coil is energized, a magnetic field is formed. The armature on the brake shaft rotates, cuts off the magnetic lines of force, generates eddy currents, and the magnetic field can promote each other to form a braking system torque. The electromagnetic eddy current brake has the characteristics of sturdiness, durability, easy maintenance, and wide speed range, but in the case of low speed, low efficiency, and high temperature, heat dissipation measures must be taken. This kind of electromagnetic brake is usually used for vertical load machinery. Electromagnetic technology friction for braking: the excitation coil system is energized to generate a magnetic field, the armature is attracted by the yoke, and the armature is braked by the connector. In addition, dry single-disc electromagnetic brakes, dry multi-disc electromagnetic brakes, wet multi-disc electromagnetic brakes, etc.
