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.
Main rated parameters
Rated torque, rated power, on-time, off-time, working air gap, rated voltage, etc.
Main materials
The iron core and armature are mostly made of No. 10 steel. For large brakes, No. 8 steel is mostly used. The windings generally use F-grade heat-resistant grades. The friction disc generally requires a friction coefficient of more than 0.5. There are also springs.
Working principle
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.
The electromagnetic power-off brake can operate reliably under the following conditions
The electromagnetic power-off brake is mainly composed of a magnetic yoke, armature, connecting plate, coil, spring, abrasive plate, gear sleeve, manual release installation and other secondary parts. The magnetic yoke is installed on the base or connecting plate by a device screw. After adjusting the air gap δ to the specified value, the coil and spring are installed in the magnetic yoke. The armature can move along the axial direction. The gear sleeve meshes with the internal teeth of the abrasive disc. When the coil is powered off, under the action of the spring force, the abrasive disc and the armature, the base or the connecting plate have a rubbing force, which is transmitted to the drive shaft through the gear sleeve for braking. When the coil is energized, under the action of electromagnetic force, the armature is attracted to the magnetic yoke, The abrasive disc is released, and the drive shaft is released from braking, which is in a free form.Main performance parameters and installation dimensions
