ELECTROMAGNETIC BRAKE

If the COMBINORM B standard flange does not fit the installation situation, it can be adapted in KEB’s in-house production process.

Changes can be made e.g. to the geometry, bore hole pattern, through holes, bolt circle arrangement, mounting slots and a bearing seat recess can be added.

If it is intended that the end products will also be used on the Canadian or American market, the relevant certification can be obtained for the COMBINORM B.

If the COMBINORM B is flange-mounted, the magnet is mounted directly on the mounting surface, e.g. the motor endshield, and the armature is attached to the shaft. 

If the COMBINORM B has a shaft-mounted design, the magnet, including the mounted armature part, is secured to the shaft. In this case, the magnetic part is fastened to the housing or bearing assembly via the mounting slots in the flange.

In the process, the magnetic part is mounted on the shaft.

The COMBINORM B version with a hub on the outside is the version that is easiest to install.

In this case, the armature is attached to the shaft outside the magnet casing.

At the customer’s request, the hub can be designed both with and without a continuous keyway and threaded holes, with threaded pins in the hub.

The COMBINORM B with hub in the magnet is used for a shorter setup than with the hub on the outside.

At the customer’s request, the hub can be designed both with and without a continuous keyway and threaded holes, with threaded pins in the hub.

The COMBINORM B without a hub is the version with the shortest axis.

In this case, the armature part is mounted directly on the mounting surface, e.g. the pinion, belt pulley or shaft end.

The torque of the COMBINORM B operating current brake can be continuously adjusted by controlling the voltage. An added advantage of this brake is that it enables energy to be saved as the torque depends on the field current and therefore power is also reduced when the torque is lower.

If the application requires a modified voltage, a customised coil with the corresponding voltage can be realised in the internal production process.

If the assembly process of the brake has to be simplified, our products can be equipped with ready-to-connect cables with plugs, contacts or even wire end ferrules.

A factory certificate 2.1 according to DIN EN 10204 that the delivered products comply with the agreements at the time of order can be provided at the customer's request. This certificate is issued based on non-specific testing. Also, an acceptance test certificate 3.1 according to DIN EN 10204 can be issued at the customer's request. In this case, the confirmation is given with the results of specific tests, such as the torque test.

Especially in the case of small brakes, energisation can lead to independent magnetisation, which means that the armature no longer detaches from the solenoid when de-energised.This should be avoided, especially in applications such as fire curtains or safety valves. KEB offers special anti remanence versions of the brake for this case.

If the standard torque of the COMBINORM B is not sufficient, the brake can be produced by KEB as a toothed version. In the case of a form-fit connection, it should be noted that these are designed for static applications and dynamic braking should be minimised.
