Permanent magnet brake CPB Series

discelectromagnetic releasesafety

Braking force of Permanent Magnet Brake is generated by a permanent magnet instead of a spring, thus it is different from a general type of spring-applied safety brake. The permanent magnet brake is composed of a spring plate and an armature, so there is no backlash on the moment of braking while power is off and no drag torque while idling during the current is supplied. While the current is cut off, the magnetic force of the permanent magnet engages an armature plate and produces rated torque. While a coil is energized, upon the excitation voltage reaches a certain level of reading, the magnetic force of the permanent magnet will be neutralized by the reverse pole of magnetic force generated from a coil. The induction force between an armature plate and the yoke will also disappear which releases the brakes. Features Quick response：Use a permanent magnet to induce an armature plate for braking force which solidifies and speeds up movement. Zero backlash：The armature plate is driven by a spring, thus torque is transmitted without backlash. Low number of decibels：As the armature plate directly connects to the spring plate, there is almost zero decibels of noise and drag torque while parts are rotating. Small volume and high torque：The use of superior quality of permanent magnet generates greater effect of torque than other types at the same size.
