Permanent Magnet Brakes - Power-Off
Product Details
KEB permanent magnet brakes have unlimited ON time and are designed for 100% duty.
Optimized Performance:
- 2nd Generation Magnetic Design: Features rare earth magnets and an efficient magnetic circuit layout for best-in-class torque density.
- Application Fit: Ideal for robotic arms, medical devices, and servo applications requiring precise positioning and secure holding. It is designed to operate across a wide temperature range.
Precision and Safety:
- Failsafe Braking: The brake engages in the absence of power, delivering reliable holding for vertical axes and emergency-stop situations.
Backlash-Free Holding: Armature and hub are riveted together, eliminating play in static or dynamic applications.
Zero Residual Torque: Engineered air gap and membrane spring design ensure complete disengagement, even under high switching frequency.
Flexible Mechanical Integration:
- Available with round or square flanges and internal or external hub options to suit tight mechanical envelopes or ease of assembly.
Class F insulation is standard (H is available upon request).
