Structure And Function Characteristics Of Electromagnetic Power Failure Brake
Release Date:11/12/2019
The electromagnetic power failure brake is composed of a yoke, an excitation coil, a spring, a brake disc, an armature, a spline sleeve, and a mounting nail. The brake is installed at the rear end of the flange (or motor) of the equipment; the drive shaft is connected with the spline sleeve and the brake disk.
When the excitation coil of the electromagnetic power failure brake is connected to the rated voltage (DC), the electromagnetic force attracts the armature and disengages (releases) the armature from the brake disc. At this time, the drive shaft normally runs or starts with the brake disc. When disconnected or powered off, the brake is also powered off at the same time. At this time, the spring presses on the armature, forcing a friction torque between the brake disc and the armature and the flange to stop the drive shaft quickly.
The power failure brake has the advantages of simple structure, wide adaptability, low noise, and reliable braking. It is widely used in the transmission of various machinery. It is an ideal actuator in industrial modernization. The power failure brake can be used safely under the condition that the relative humidity of the surrounding air is not more than 85%. The B-type insulation is used around the brake, and the voltage fluctuation does not exceed + 5% and -15% of the rated voltage. Its working mode is continuous operation.
Tianji Transmission, a professional manufacturer of electromagnetic power failure brakes, especially reminds you that after installing the power failure brake, you must screw out the hollow bolt and lock it on the motor rear cover or flange. Welcome to call for detailed inquiry and online selection!
