Description

This product combines the well-known properties of permanent magnet brakes - Due to a re-design of the magnetic circuit, it features further advantages such as a higher torque at identical size and power consumption, high torque constancy throughout the complete service life and an extended temperature range. Operating principle The High Torque 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 High Torque brake with zero residual torque. Thanks to these features, High Torque brakes are ideal for servo motor applications. Brake design The firmly fitted field coil is installed between the housing and flange of the High Torque brake. The flying leads required to connect the field coil exit at defined positions on the brake. The permanent magnets installed in axial direction between the housing and flange generate the magnetic field required to produce the braking action. The armature is connected with the flange hub by means of segmental springs and rivet fasteners to establish an axially movable, torsion-proof and friction-free connection. This ensures zero residual torque during horizontal or vertical brake operation.
