The PM Line On the point – Fail-safe permanent magnet brake – Holding brake with emergency stop function – In total 10 different sizes available – Torque range from 0.01 Nm to 240 Nm – Temperature range from -5°C to +120°C Robotics & Automation Machine Building Medical Tech

Massive power needed? Due to their high power density, wear- and residual torque-free operation and short switching cycles permanent magnet brakes are in most cases the optimum solution in robotics and machine building. Above all, permanent magnet brakes convince by their compact dimensions and their relatively low weight. Thanks to the high power density of the permanent magnets, the torque achievable with the given installation space is twice as high as usual with spring-applied brakes. Furthermore, due to their design principle permanent magnet brakes are backlash- and wear-free. Thus,...

Ideal for integration into servomotors – Designed for integrated installation in the motor – A- and B-side mounting position on the fixed bearing possible – Integration in non-motor applications possible e.g. hand-guided tripods Technical highlights – High variance due to modular design – Extended lifetime up to 2,000 emergency stops – Torque transmission without backlash – Residual torque-free opening regardless of mounting position – Wear-free with dynamic changes of

Brake types The PM Line was especially designed for integration into servomotors and offers different options for the brake configuration. Depending on the size, it is possible to combine the stator system with different coil and armature systems. Please see the table on page 8 for different combination options. We will be pleased to discuss your individual requirements and develop your specific solution. Stator types Type 611 Front side mounting Flange side mounting Armature types Type 200

Armature types We have compiled a selection of our different armature systems for you. The armature systems depend on the brake type and size. Armature type 200 Without hub – Hub in responsibility of customer – Armature-hub interface acc. specifications – Air gap adjustment by customer Armature type 300 Manual air gap adjustment – Short hub – Fixing thread outside brake – Air gap adjustment by feeler gauge Armature type 400 Manual air gap adjustment – Short hub – Fixing thread inside brake – Air gap adjustment by component position Armature type 800 Automatic air gap adjustment – Long hub...

Modular system Integrated brake systems as used in servomotors usually require customized solutions. The PM Line with its modular system – consisting of stator, armature and coil system – offers the necessary flexibility. Our goal is to configure a customised brake quickly and efficiently with a minimum of development effort to adapted the customer's requirements. Furthermore, we also offer solutions outside of the modular system in coordination with our customers.

Permanent magnet brakes from KENDRION High performance density and precision Permanent magnet brakes are primarily used in applications in which high performance density is essential. Typical examples are powerful servomotors, high-quality machine tools, robots, and wind turbines. Wherever precision matters or high demands on ambient temperatures need to be met, permanent magnet brakes are our customers’ first choice. It is the primary task of the brake to hold high loads. The backlash-free shaft-hub connection ensures that a very high positioning and holding precision can be achieved by...
