Permanent magnet brake Slim PM

The Slim PM Line is a compact, lightweight and cost-efficient permanent magnet brake for servo motors with low to medium braking torque requirements.

How much brake does your servo motor need?

Servomotors must meet high standards for performance, precision, and compact design. The sizing of the integrated brake also plays a crucial role here. After all, not every servomotor requires the same braking torque.

Brakes are often used whose performance exceeds the actual requirements. Especially for servomotors with low and medium torque requirements, this oversizing can lead to unnecessary weight, additional installation space, and higher costs.

More compact. Lighter. More economical.

With the Slim PM Line, Kendrion offers a compact permanent magnet brake specifically designed for servomotors with low to medium braking torque requirements. It combines high power density with a cost-effective design and enables brake sizing tailored to specific needs. As a fail-safe holding brake with an emergency stop function, it ensures maximum operational reliability—even under demanding conditions ranging from -40°C to +120°C.

With six sizes and a braking torque range from 2.7 to 17 Nm, the Slim PM Line meets the diverse requirements of modern servo drives. Its compact design reduces weight and overall length, paving the way for smaller and more cost-effective drive solutions.

One interface. More possibilities for your motor platform.

The Slim PM is a permanent magnet brake that has been specially developed for servo motors in the low and mid-torque range. It complements the High Torque Line, which is designed for larger servo motors with its enormous braking force of up to 280 Nm. The Slim PM Line has the same interface, but is significantly more compact and highly cost-effective. Thanks to the identical interface of both lines, designers benefit from maximum flexibility – without any adjustments to the motor design.

FAQs: Slim PM Line

What is the Slim PM Line?

The Slim PM Line is a series of compact permanent magnet brakes specifically developed for servo motors in the low- and mid-torque range. It complements the High Torque Line, and together they form the perfect duo for servo motor applications – sharing the same mechanical and electrical interface.

How does the Slim PM differ from the High Torque Line?

Both brake lines share the same mechanical and electrical interface, making them fully interchangeable. The Slim PM, however, is optimized for smaller and medium torque ranges and stands out for its exceptionally compact design and attractive price-performance ratio.

What advantages does the Slim PM offer compared to spring-applied brakes in low and mid-torque motor sizes?

The Slim PM Line delivers significantly higher torque than conventional spring-applied brakes at the same size, enabling more compact and powerful servo drives. With its cost-efficient design, it matches spring-applied brakes in price while offering the superior performance of permanent magnet technology. Mechanically and electrically identical to Kendrion’s High Torque Line, it allows the use of a unified interface across different motor power classes. Its compact design reduces installation space by up to 25 % and allows motors up to 5 % shorter. The Slim PM is maintenance-free, backlash-free, and wear-free, ensuring high precision, fast switching times, and energy-efficient operation.
