Non-excited operation type permanent magnet brake
A permanent magnet electromagnetic brake that achieves high-speed response through backlash-free design.
The 【CPB/PB1/PB2 series】 generates braking force through the magnetic force of permanent magnets, unlike spring-type brakes. The armature uses a leaf spring drive system, resulting in no backlash in the rotational direction and no drag torque. 【Features】 1. High-speed response: The magnetic force of the permanent magnets attracts the armature to the magnet side, providing quick responsiveness. 2. No backlash: The armature's leaf spring drive system ensures there is no backlash when transmitting torque. 3. Quiet operation: The armature is directly connected to the leaf spring, resulting in no noise during rotation and no drag torque. 4. Compact: By using high-quality permanent magnets, it achieves higher torque even with the same size. Torque range: 0.4 Nm to 140 Nm Smallest outer dimensions: 19.5 × 39 The PB1/PB2 series comes with a hub. *For more details, please refer to the materials available by downloading the catalog.
basic information
- The armature is attracted to the magnet side by the magnetic force of the permanent magnet, and the response is quick. - The leaf spring drive system transmits torque without backlash. - The armature is directly connected to the leaf spring, resulting in no noise during rotation and no drag torque. - By using high-quality permanent magnets, it achieves higher torque even with the same size and has a longer lifespan.
