SPRING-ACTUATED BRAKES ELECTROMAGNETIC CLUTCHES & BRAKES BXR Models Items Checked for Design Purposes ■ Precautions for Handling Most electromagnetic braking systems are made using flexible These brakes are holding brakes. Do not use them for ordinary braking, materials. Be careful when handling such parts and materials as except for emergency braking in the event of a power outage or the like. striking or dropping them or applying excessive force could cause them to become damaged or deformed. ■ Lead Wires Be careful not to pull excessively on the brake lead wires, bend them at sharp angles,...

351 ■ Precautions for Mounting ■ Affixing the Rotor Hub Affix the rotor hub to the shaft with bolts, snap rings, or the like such that the rotor hub does not touch the armature or stator. Leave at least ■ Recommended Power Supplies and Circuit Protectors Recommended power supplies dimension J/J1on spline hub types, since the rotor hub may contact Brake voltage ■ Mounting the Brake Implement screw-locking measures such as use of an adhesive threadlocking compound to bolts and screws used to install brakes. If using a spring washer to prevent loosening, use a conical spring washer, and ensure that...
