What is the torque transmission principle of the dry single-piece electromagnetic power loss brake?
Release time:
2021-11-19
The dry single-piece electromagnetic power-loss brake can be divided into two types. One is to use the elasticity of the brake to generate unpowered braking force on the motor rotor. After the power on the excitation coil is turned on, the brake disc and rotor are fixed on the rotor shaft by electromagnetic force.
The dry single-piece electromagnetic power-loss brake can be divided into two types. One is to use the elasticity of the brake to generate unpowered braking force on the motor rotor. After the power on the excitation coil is turned on, the brake disc and rotor are fixed on the rotor shaft by electromagnetic force. The separation of the friction plate is to eliminate the braking state, that is, power-off braking; second, when there is no power, there is no braking force. The shaft can rotate freely, but the braking force will only move after the excitation coil is energized.
When the electromagnetic brake coil is charged, the armature is pressed against the friction plate or the brake yoke of the rotor by electromagnetic force, thereby realizing the combination of the driving side and the driven side to transmit power. When the coil is cut off, the electromagnetic force disappears, the armature returns to its original position under the action of the spring resilience, the armature is separated from the rotor or the brake yoke, and the power transmission effect disappears.
As a kind of automatic actuator in modern industry, electromagnetic power loss brake mainly plays the role of transmitting power and controlling motion to mechanical equipment. It has the advantages of fast response, simple operation, compact structure, reliable use and easy remote control.
The dry single-piece electromagnetic power-loss brake is a connector that transmits torque from the active side to the passive side. It can be freely combined, cut off or braked as needed. Start with the electromagnetic force. This ideal automatic actuator mainly transmits power and controls movement in the mechanical transmission system.
In order to ensure the uninterrupted operation of the electromagnetic power-off brake, the electromagnetic power-off brake must be maintained frequently:
1. Always add lubricant to the moving parts of the engine.
2. If the worn brake surface is replaced, the small gap between the brake surface and the turntable should be properly adjusted again.
3. Regularly check the length of the armature stroke. Because during the operation of the electromagnetic brake, the stroke length of the armature will increase due to the wear of the cutting surface. When the armature stroke length cannot reach the normal value, adjustments must be made to restore the small gap between the braking surface and the turntable. If the armature stroke length increases beyond the normal value, the suction force may be greatly reduced.
4. Regularly check the fastening degree of bolts, especially electromagnet bolts, electromagnet and shell bolts, yoke bolts, electromagnet coil bolts, and terminal bolts.
5. Regularly check the mechanical wear of the moving parts and remove the dust, flower hair and dirt on the surface of the electromagnet parts.
The electromagnetic power-off brake also has the following functions:
1. Non-contact torque transmission: The air gap of the brake or clutch of the mechanical part is constantly changing, and then becomes constant to avoid any wear.
2. Continuously adjustable torque: The braking torque or transferable torque depends only on the current and is largely independent of speed. It is continuously effective from zero to speed.
3. High power continuous mode, overload: power optimized braking series can withstand high power continuously. It can withstand overload in a short time.
4. High speed, up to 15000rpm.
