SEB-Max™ Operation:
The magnet body is attached to a fixed surface that can react the shaft torque and the friction disk interfaces directly with the shaft with the provided drive feature. When the coil is energized the electromagnetic field attracts the armature plate and compresses the springs. This allows the friction disk to rotate freely with the shaft.
After about one second of energization at the pull in voltage the brakes should be reduced to the holding voltage. This voltage will maintain the disengaged state while reducing power consumption and heat generation. Most applications will need to utilize the hold voltage to prevent thermal stresses in the brake but specific duty cycles can be reviewed by SEPAC.
When power is turned off, the electromagnetic field dissipates, allowing the springs to push the armature plate into contact with the friction disk. This squeezes the friction disk between the pressure plate and the armature plate, thus transmitting torque, and stopping/holding the friction disk and shaft.
