What are the applications of electromagnetic brakes in motors?
Release time:
2022-08-19
Electromagnetic brake is a common additional device for motors, and there are two types of power-on braking and power-off braking. The electric braking method is fast and accurate in positioning, and is used for automatic intelligent control equipment that requires precise positioning. It has certain limitations in application occasions; electromagnetic power loss brakes (hereinafter referred to as brakes) are widely used.
Electromagnetic brake is a common additional device for motors, and there are two types of power-on braking and power-off braking. The electric braking method is fast and accurate in positioning, and is used for automatic intelligent control equipment that requires precise positioning. It has certain limitations in application occasions; electromagnetic power loss brakes (hereinafter referred to as brakes) are widely used. Mechanical transmission systems with positioning and braking requirements, such as machine tools, metallurgy, motors, chemicals, construction, packaging and printing, textiles, and automated production lines, have been widely used. In addition to the advantages of convenient operation and fast braking speed, power-off braking also means that the equipment can be safely braked in the event of accidental power failure and out of control to ensure the safety of personnel and facilities.
The structural advantages and characteristics of electromagnetic brake:
1. Compact structure. Although the axial size of the power loss brake is small, the braking torque is large enough.
2. Fast response power-off braking adopts spring energy storage device to form braking torque, and the reset time of spring and arrow is the braking response time.
3. Long service life. New friction materials are used for power-loss braking to determine the performance of high service life.
the working principle of electromagnetic brake:
Electromagnetic power loss The electromagnetic brake is mainly composed of magnetic choke, armature, connecting plate, spring, friction plate, gear sleeve and other parts equipped with coils. The spring is installed in the magnetic choke, and the armature can move in the axial direction. The magnetic choke is fixed on the base by mounting screws and the gap is adjusted. After reaching the specified value, the gear sleeve is connected with the drive shaft through a key, and the outer teeth of the gear sleeve mesh with the inner teeth of the friction disc.
When the coil is de-energized, the friction plate generates friction with the armature and base (or coupling plate) under the action of the spring force, and the drive shaft is braked by the gear sleeve. When the coil is energized, the armature is attracted to the magnetic choke under the action of electromagnetic force, thereby releasing the friction plate and releasing the brake.
working conditions of electromagnetic brake:
1. The relative humidity of the surrounding air is not more than 85%(20±5 ℃).
2. There is no corrosive metal and gas or dust that damages insulation in the surrounding medium.
3. Class B insulation shall be adopted around the brake, and the voltage fluctuation shall not exceed + 5% and-15% of the rated voltage. Its working mode is the continuous working system installation control requirements.
4. The matching accuracy of the drive shaft and the brake should be ensured during installation.
5. The brake must be cleaned before installation, and there must be no oil and dust on the friction surface and inside the brake.
6. The gear sleeve must be axially fixed.
The choice of the type of electromagnetic brake depends to a large extent on the required braking torque. In addition, the moment of inertia, relative speed, braking time, working frequency and other factors should be considered. The following are the modeling rules recommend by brake manufacturers. Different manufacturers will have some differences, but the principle is similar.
maintenance of electromagnetic brake:
1. After the brake is used for a period of time, due to the wear of the friction parts, it is necessary to readjust the gap value by adjusting the screw, nut, adjusting sleeve, etc. to make it meet the specified value.
The friction surface should always be clean and free of impurities.
