PB1 Permanent Magnet Brake with Long Hub

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. 

• Structure

• 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.
