Description

The PM Line includes permanent magnet brakes in which the braking force is generated by a permanent magnetic field. The brake thus works in a de-energized condition and fulfill the following functions: Holding, positioning and emergency stop. The neutralization of the braking force is effected by the counteracting electric field, granting a high degree of security, even in the case of power failure. Permanent magnet brakes are characterized by a secure, residual-moment-free lifting in any position, and by a backlash-free transfer of the braking torque. Operating principle The permanent-magnet single-surface brake is designed to operate dry. The force generated by a permanent magnetic field is utilised to produce the braking effect. To neutralise the braking action, the magnetic flux of the permanent magnets is cancelled by an alternate electromagnetic field (electromagnetically released system). The zero backlash connection between the armature and flange hub ensures zero backlash transmission of the brake torque to the machine shaft (e.g. motor shaft) and reliable release of the permanent-magnet single-surface brake with zero residual torque. Thanks to these features, permanent-magnet single-surface brakes are ideal for servo motor applications.
