Electromagnetic power-off brake (power-off brake) has the advantages of compact structure, convenient installation, wide adaptability, low noise, high working frequency, sensitive action, and reliable braking. It is an ideal automatic actuator. It is widely used in metallurgy, construction, chemical industry, food, machine tools, printing, packaging and other mechanical equipment, and in the event of power failure (risk prevention) braking and other occasions.
Electromagnetic power-off brake (power-off brake) has the advantages of compact structure, convenient installation, wide adaptability, low noise, high working frequency, sensitive action, and reliable braking. It is an ideal automatic actuator. It is widely used in metallurgy, construction, chemical industry, food, machine tools, printing, packaging and other mechanical equipment, and in the event of power failure (risk prevention) braking and other occasions.
The electromagnetic power-off brake is also called the power-off brake. Its working principle is that when the excitation coil is connected to the rated voltage DC24V, the electromagnetic force attracts the armature to separate (release) the armature from the brake disc. The disc is running or starting normally. When the transmission system is separated or powered off, the brake is also powered off at the same time. At this time, the spring presses the armature, forcing friction torque between the brake disc and the armature and flange to stop quickly. When the brake heat dissipation environment is poor and the drive shaft is working continuously for a long time, if conditions permit, the voltage can be converted to 70%-80% of the rated voltage after the brake is working to reduce heat generation.Electromagnetic power loss brake is widely used in metallurgy, construction, chemical industry, food, machine tools, printing, packaging and other machinery, and in the power failure (anti-risk) braking and other occasions. This kind of brake has the advantages of compact structure, convenient installation, wide adaptability, low noise, high working frequency, sensitive action, reliable braking, etc., and is an ideal automatic actuator.
The rated parameters of electromagnetic power loss brake: rated torque, rated power, on time, off time, working air gap, rated voltage, etc.
The main material of electromagnetic power-off brake: iron core and armature are mostly made of No. 10 steel. For large brakes, No. 8 steel is mostly used. The winding generally uses F-grade heat-resistant grade. The friction disc generally requires a friction coefficient of more than 0.5. There are also springs.
The brake is externally connected with a half-wave rectifier to rectify single-phase alternating current into direct current. After the winding is energized, a magnetic field is generated, which attracts the armature back, and the armature compresses the spring fixed in the core. When the power is lost, the winding discharges, the spring ejects the armature, and the armature generates braking torque on the friction disc to stop the motor.
