Friction brake COMBIPERM P2

Product description
The COMBIPERM P2 is a very compact and powerful permanent magnet brake with a frictionally engaged, backlash-free effect. Compared with the COMBIPERM P1, the brake has a shorter assembly space and requires less power for increased performance. Due to its construction, it is suitable for use at temperatures down to -40°C. When energised, the magnetic field of the permanent magnet is cancelled and the connected component can rotate without residual torque. In the event of an emergency stop or power loss, the safety brake engages, brakes and holds the drive securely in position. Short switching times and the compact design make these brakes ideal for servo motors and the medical sector.

Product range
The torque range of the high-performance brake is 2.8 Nm to 20 Nm and it is available in sizes 03, 04, 05, 06 and 07.

Options

• Cable protector: The COMBIPERM P2’s connection cable can optionally be fitted with a cable protector to prevent damage; recommended where the cable is routed axially in confined spaces.
• Felt ring: To protect the COMBIPERM P2 and the braking torque against oil leaking from adjacent bearings, a felt ring can be optionally fitted.
• Rear screw connection: For extremely small assembly spaces, a rear screw connection is available so that no additional flanges are needed.
• Round flange: For round assembly spaces or round bearing plates, a version with a round flange can be supplied.
• Adapted screw connection / customised mounting: If the standard screw connection does not fit the mounting situation, the brake can be customised with a flange, a modified borehole pattern and bearing seat recess.
• Customised bearing seat insert: If a bearing is to be used between the brake and motor bearing shield, a bearing seat insert can be produced internally.
• Hub in the magnet: The hub is located in the magnet as standard to achieve the shortest possible assembly length.
• Customized cable assemblies: Products can be supplied with ready-to-connect cables with plugs, contacts or wire end ferrules to simplify assembly.
• Certificates: A factory certificate 2.1 (DIN EN 10204) can be provided on request; an acceptance test certificate 3.1 (DIN EN 10204) with specific test results (e.g. torque test) is also available on request.
