ELECTROMAGNETIC BRAKE
COMBINORM B
The operating current brake COMBINORM B opens when the power supply is switched off or in the event of a power failure. The electromagnetic brake is particularly suitable for precise positioning and reliable holding. It is also used in safety and access technology, e.g. in the area of access barriers or fire doors. The electromagnetic brake is designed for a 100 % duty cycle and can optionally be certified to VdS.
The electromagnetic brake has a torque range of 0.5 Nm to 500 Nm.

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.
