2022-03-16
Electromagnetic brake is an ideal automation actuator in modern industry. It mainly transmits power and controls motion in the mechanical transmission system. It has the advantages of compact structure, simple operation, sensitive response, long service life, reliable use, and easy remote control.
Classification knowledge of electromagnetic brake
Brakes are mechanical parts that stop or decelerate moving parts in machinery. They are commonly known as brakes and brakes. They are mainly composed of brake frames, brake pads and operating devices. Some brakes are also equipped with automatic brake clearance adjustment devices to reduce braking Torque and structural size, the brake is usually installed on the high-speed shaft of the equipment, but large equipment with high safety requirements, such as mine hoists, elevators, etc, it is installed on the low-speed shaft near the working part of the equipment. The brake has been standardized and serialized, and is manufactured by a professional factory for selection.
Electromagnetic brake is an ideal automation actuator in modern industry. It mainly transmits power and controls motion in the mechanical transmission system. It has the advantages of compact structure, simple operation, sensitive response, long service life, reliable use, and easy remote control.
Electromagnetic brakes are mainly matched with series motors and are widely used in metallurgy, construction, chemical industry, food, machine tools, stages, elevators, ships, packaging and other machinery, as well as braking during power outages. The resistance torque that must be applied to stop or decelerate the running parts of the machinery is called braking torque. The braking torque is the basis for designing and selecting brakes, and its size is determined by the type of machinery and working requirements, the performance of the friction material (brake parts) used in the brake directly affects the braking process. The main factors affecting its performance are the working temperature and temperature rise rate. The friction material should have a high and stable friction coefficient and good wear resistance. The friction material It is divided into metal and non-metal. The former is commonly used cast iron, steel, bronze and powder metallurgy friction materials, and the latter is leather, rubber, wood, asbestos and non-asbestos.
Brakes using electromagnetic effects can be divided into electromagnetic powder brakes, electromagnetic eddy current brakes and electromagnetic friction brakes
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 to form a magnetic powder chain, which gathers between the fixed magnetizer and the rotor. 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 released. This brake is small in size, light weight, low in excitation power, however, magnetic powder can cause component wear, which is convenient for automatic control and is suitable for the drive system of various machines.
2. Magnetic eddy current brake: After the excitation coil is energized, a magnetic field is formed. The armature on the brake shaft rotates, cutting the magnetic lines of force, and generating eddy currents. The eddy current in the armature interacts with the magnetic field to form a braking torque. The eddy current brake is durable and easy to maintain., Wide speed range, but low efficiency at low speed, temperature rise, heat dissipation measures must be taken. This kind of brake is often used in machinery with vertical load.
3. Electromagnetic friction braking: The excitation coil is energized to generate a magnetic field, the armature is attracted by the yoke, and the armature is braked by the coupling. In addition, it is subdivided into dry single-plate electromagnetic brakes, dry multi-plate electromagnetic brakes, and wet multi-plate Electromagnetic brakes and so on.
